Bethany Leone: Welcome everyone to another episode of Heat Treat Radio. We are sitting down with Rick Kaletsky. He has a lot of experience, as a consultant, with occupational safety. Rick, can you tell our listeners and viewers a little bit more about yourself, your background, and anything else you want?

Rick Kaletsky: Thank you. I’ve been in occupational safety for 50 years. I live in Connecticut, always have. The main parts of my career were 20 years with U.S. Department of Labor (OSHA) in Connecticut. As a compliance officer, I conducted hundreds of inspections. As assistant area director, I assigned and reviewed thousands, and held informal conferences. On many days, I acted as area director for the whole state, but still through the federal office.

Rick is an expert on Muhammad Ali.

I’ve been on my own as a self-employed safety consultant for 30 years. Although I’ve done a wealth of inspections in that situation, I’ve pretty much gotten into now, in almost all cases, working for attorneys. These very serious occupational injuries, and occasionally nonoccupational, like  trips and falls in a mall, etc. I testified either by deposition or in court more than 60 times, and I’ll provide information about a book I wrote (see end of transcript, or purchase book here). Sidenote, the book I wrote about Muhammad Ali is even better than the OSHA book!

Bethany Leone: We’re here with Rick to specifically navigate osha.gov.

Rick Kaletsky: It is osha.gov. It’s important for everyone to know, please do not use .com, .net, or .edu. You’ll get something else.

United States Department of Labor Occupational Safety and Health Administration

I have the screen in front of me now. This is United States Department of Labor Occupational Safety and Health Administration. You all should see a red banner across the top. It’s quite user friendly. You can use it for many, many purposes. It’s free — why not use it? You can use it to find OSHA standards. You can use it to find directives and interpretations which give you an idea of what are some special things about standards that do not appear in them:

  • For instance, an interpretation is generally when Johnny Smith from the ABC company in Nebraska writes to OSHA and wants to know, “Regarding this standard, am I in violation if . . . Or what are alternative means, etc.?” OSHA will answer. But those answers are not in the standard, so there are some special things there.
  • A directive is a similar thing that the national office of OSHA communicates to its people in the field, mainly for compliance officers who do inspections, on how to view certain situations, how to look at what might be a violation or what is not a violation.

You can also use this site for tutorials, for finding publications, downloading them, printing them, and certainly to find the records of companies. You will find, not their injury and illness record, but rather, when they were they cited by OSHA for allegations, and which particular standards.

In roughly half the states, the federal government enforces the standards. Now, there is a Nuclear Regulatory Commission; there is a railroad administration — there are a few things that aren’t covered and few people working absolutely alone.

Just figure: If you have an employer-employee relationship, barring some unusual exceptions, they’re covered by OSHA. If you figure we have a small family heat treating business of 6 people, yes, you’re in.

In about half the states, the federal government does the enforcing. In the other half, the state does the enforcing. A few states have even addressed standards and come up with rules (laws) that federal OSHA doesn’t cover, like ergonomics.

If you’re in a federal state, you are dealing with 29 CFR (Code of Federal Regulations, 1910 ). Some iterations of CFR 1910 refer to exits, some to powered industrial trucks or vehicles, some to lock out/tag out, some to personal protective equipment, some to ladders, etc.

Some of the states that do their own enforcing and use the exact same standards as OSHA. For the heat treating industry, it is going to be 1910 point. There are a few that begin with something like 1902 or 03, regulating injury/illness records and posters. Just about everything else is 1910. So, that tells you a lot about standards.

In Maine, there’s a federal OSHA office in Augusta, Maine and in Bangor, Maine. You might have to figure out which one covers you if you have a question.

Now, every state has a consultation program. As a relatively small company, you can get the state to come in for free as long as you’re not in the middle of an enforcement inspection. You could say, “I don’t want to pay a private consultant.” The state comes in, and they tell you what they think is wrong. If you’re concerned that they’ll run back to federal OSHA — no, no; they know that that would freeze your interest.

They will tell you what needs to be done, where you may be breaking the law, and they give you a while to deal with it. There is no penalty. Will they run back to the enforcement people, whether it be the federal people or the state people? They will not . . . unless you steadfastly refuse to correct something even with extensions of time.

"Standards" and "Law and Regulations"
Source: OSHA

We’re going over to “Standards," and you see the arrow that points down. When you hit that, you see “Law and Regulations." For now, let’s try that.

When we hit “Law and Regulations” on the left there should be a column where it says “General Industry." These are the federal numbers for standards, but they often apply to states anyway. Here we find specific standards. I’ll try to stop on a few.

On the left, you’ll see “Ladders” and that goes back into 1910 point 20. You’ve got to know whether you’re talking about a stepladder or an extension ladder or a fixed ladder.

“Walking/working surfaces” applies to anything to do with fall protection. In your industry, that could mean you may a mezzanine that doesn’t have perimeter protection or a tie-off to a person. And sometimes you have somebody working on top of a furnace, more than four feet high. If that person isn’t protected, there is a problem.

Where in these standards do I find heat treating?
Source: OSHA

Where in these standards do I find heat treating?

Well, it’s possible those particular words are somewhere, but there is no particular section here just for heat treating. There are very, very few specific industries that have a section that is dedicated to them. But pretty much all of 1910 can apply whether you manufacture submarines or bowling balls, or you just have a store or a warehouse or an ice cream factory.

Let’s look at “133 Eye and Face Protection”. This is what I really wanted to show you. See it says “Standard Interpretations”?

"Here you're right in the standard."
Source: OSHA

Now, there are other ways you could have done that by just the general OSHA search bar “Interpretations” or “Eye protection interpretations” perhaps. But here you’re right in the standard. So, when you hit “Standard interpretations”, we see “Request to provide” list of corrosive materials and concentrations requiring use of emergency eyewashes and showers. That actually applies to another standard also, it’s not just eye protection. It’s the fountains. Let’s hit “Request to provide”.

Here someone wrote to OSHA and said, “When do I need an eye fountain or eye protection or both?” And OSHA wrote back and said, “Well, there might be some twists, this isn’t all encompassing. This is where we try to answer your questions.”

Many years ago, a heat treater comes to me and says their company got cited for a problem with dip tanks. Now, this standard has been changed since. Dip tanks are an example, when you read that standard, you should always see what the application and scope are.

Does this apply to me? But with dip tanks, it gets so specific that you’ve got to have this kind of substance, and this is only if dip tanks have so much volume or so much surface area, etc. Well, they got cited for a few things.

I said, “Let’s look at the standard. Not just the way it applied and is shown on the citation but the complete writeup of the standard.” Is your dip tank this size or bigger? Yes. Does it have this much stuff in it? Yes. Is it flammable? Yes. Well, they got you. You’re going to have to do what it says.

The heat treater said, “But, Rick, we’re not even concerned about this penalty, but to correct that is going to cost us well over $100,000 because of permits and  outside location.” I said, “I don’t know what I can do for you.” They said, “Do something!”

So, I found an interpretation or directive which did not get added to the standard that indicated an alternative abatement to what I said. Not even all the compliance officers get to remember these things.

It said as long as you also have a written plan, and you have redundant extinguishing automatically, even though that, in itself, is not required by a standard. If you do these special things, don’t sweat the reservoir.

I went into the office with him, in Massachusetts, and even the assistant area director said, “What are you showing me? I’ll get back to you.” And he looked it up and said, “Well, the[blocktext align="left"]And according to this company, it saved them tens and tens and tens of thousands. So, you do need to know where that kind of thing is in the whole body of the standards.[/blocktext] citation stands, but abatement will be considered complied with if you just do this other thing which is a lot easier.”

And according to this company, it saved them tens and tens and tens of thousands. So, you do need to know where that kind of thing is in the whole body of the standards.

Now, before I go too much further on the standards, when I mentioned application and scope, don’t forget to look at definitions. Sometimes, very close to a particular standard, it will literally say definitions. Other times, at the beginning of a subpart, it has sets of standards, and this is not as complicated as you might think. You’ll see this when you go in. It might have the definitions up front. So, somebody might say, “Well, aren’t most things obvious?”

Just to give you an example: In the world of OSHA, “a hole” and “an opening” are not necessarily the same. So, sometimes whether you have to do something or whether you supposedly violated a standard, it has to do with the definitions.

Definitions help you follow the standards.
Source: OSHA

You will also see exceptions sometimes. You’ve got to read carefully.

“Topics” is the next one. It has some, but not all, topics.

You can also use the “Search OSHA” option with key words. There is also an A-Z index.

“Help and Resources” and “News” are also available.

Under “News,” — on March 9, 2023 — we have an item about an auto parts seller. The point is, they got a bill for 1.2 million dollars. Are they going to argue that? Sure. I want you to know there are some serious penalties out there. The penalties went up again in January of 2022. That is the maximum allowable for OSHA to cite under different categories.

Now let’s look at the A-Z index.

A-Z Index
Source: OSHA

There are publications under “P”. You don’t have to get them sent to you, and they print less. Now they want you to download them, or they’re in English or  Spanish. They’re not all-encompassing. They might say that this is not a substitute for a standard. But there are other things under there.

There is something I really want to show everybody in the A-Z list. Look under says “Data and Statistics” and the “Establishment Search”. “Establishment Search” means a particular company and specifically where they are, where OSHA visited. It doesn’t matter if corporate was in another state.

Now look at “Search Inspections” by NAICS (North American Industry Classification System). It shows that near the bottom of this list. A SIC code is a standard industrial classification.

What does that mean?

Every company has given them a SIC number.

"What the federal government likes to use now is an NAICS number."
Source: OSHA

What the federal government likes to use now is an NAICS number.

Metal treating is generally 332811. You can find that with key words on the left.

Now, everybody who makes pillows, let’s say, could be a 35062. Everybody who is primarily a septic tank service is a 17682, and every department store is a 48605.

When the government does that, it can start to get close to figuring out in what industries there are the most problems of certain sorts. And you can find here, where is says “Frequently Cited OSHA Standards”, what is most commonly found in your industry.

Here is a major caution in your particular business. There are certain kinds of factories that are all over the place, certain kinds of warehouses and stores. OSHA is shorthanded, and in the particular coding for metal treating and heat treating, the sampling for a year isn’t that large.

So, when you see these citations, they could be skewed. OSHA might have only gone into a few places, and they may find different things at your place.

Now, let’s go to “Establishment Search”. I went ahead on this so I could give you an example. See where it says “Establishment”? I’m not picking on anybody; as a matter of fact, I found a couple companies that don’t have a lot of stuff, and nobody should be embarrassed or anything like that.

Bethany Leone: We're typing the name of a company into the search engine and reviewing what other items one ought to refine when searching the company records.

Rick Kaletsky: You see where it says 2017–2022? I would not go back more than five years for this reason: This system has a problem with large bites.

So, for this example company, you’ll see the OSHA inspection started September 13th. It was a planned inspection. So, OSHA did not go in to just look at where something bad happened, or just look at a very particular area of concentration that OSHA was doing a priority on.

It gives that NAICS of 332811. It indicates three violations. It was mainly safety.

A safety person could find a little something with industrial hygiene or vice versa — that wasn’t their main reason why they were in. The safety person might have wondered about some hygiene stuff and did an intraoffice referral; a hygienist could come in later. There was a closing conference in October. The case closed in January of 2020.

Let’s look at the violation summary for this company. The only confusion here, is they group citations sometimes. You may wonder how can that say “3” or “1” but below it looks like you see more? I’ll explain how they group some items but overall make all that 1 item.

Originally, OSHA found what they allege to be 3 serious violations, but something happened where it was either contested or they made a deal with the OSHA office. They went in and said, “Look, we’ll be good. It’s a mistake. Here are the extra things that happened.” Or they said, “You’re wrong OSHA. Can we work it out that way? Can you fix this?” So, they had an informal settlement agreement. The initial penalty was $26,000, and it was cut to $7,000.

The way it stands now is this: OSHA doesn’t usually have that many “others”, it’s usually a lot of “serious”, but they made a deal with the company.

Violations chart
Source: OSHA

The most important thing here is you don’t have “willful”, “failure to abate”, or “repeated”. Those have a stigma to them. And those dollar amounts could be things you don’t want to get involved in.

So, in the end, here’s what the IT people in DC should fix: Under standard — you see something that looks like, “What? What is that? Is that 19 million or 1 million 900 thousand?” No, no, no  we should fix this. 1910.28(B)(3)(ii).

If a person doesn’t have experience with OSHA, they could say, “What is B03, etc.? What is 1 million 900?” It means 1910 point, not a dollar amount. It means the current penalty is nothing, even though the initial was more by informal settlement agreement, and it explains it.

They then group two things. Now what is the 28? We could look it up, but it has something to do with fall protection. 178? Two things to do with power industrial vehicles, probably meaning fork trucks or something similar. 219 has to do with power transmission equipment, belts, chains gears, etc.

That’s how this works. You can look up any company to see how your competitors are doing or to really find out what your history was with OSHA.

Bethany Leone: We are back to the “Establishment Search” and searching another company and scrolling through those results.

Rick Kaletsky: In this example, we’ve dates here. They had an initial penalty of $50,000 and a current penalty of $16,000 — that’s just on “Serious”. Then they had some other things change. The penalty went from $50,000 to $20,000.

I do not want to leave the impression that as you walk into an OSHA office in 2022 and you say, “We’re sorry, can you take $30,000 off?” Don’t bet on it.

You better have a darn good reason to say we really should have a break, you shouldn’t have cited us for it, or there were mitigating circumstances you didn’t know about, or we really would appreciate it if you didn’t call this a “repeat” but called this a “serious”. You’ve got to have something to say.

"OSHA completely took out that 132A."
Source: OSHA

In one case here, you see “deleted” for number 2. So, OSHA completely took out that 132A that way. They left off this personal protection one. Now, sometimes they take one out, and they add one. So, this company was cited for 1910.28 and change, that is 28B1i, something to do with fall protection. 132A, that’s not there anymore though, personal protection 147 is lockout/tagout, 215 is abrasive wheel machinery (usually meaning a grinder), and 219 is power transmission equipment.

All this was dealt with by an informal settlement agreement. The company did not contest; it was done by a deal with the office.

CTRL+ F is a great tool for the OSHA website. You may not want to read 80 pages, and with this tip, you can get to these things in a hurry.

Bethany Leone: For heat treaters, this is really important. If you know you’re being cited for something, or if you’re interested to see what type of standards might be pertinent to you. For the heat treat industry, it’s not going to be that particular, but you might find that there are things that you do repeatedly that you need to know about. For example, working on top of a big furnace, this is how you navigate this site.

Rick Kaletsky: There are two things I want to say:

It’s one thing if you call me, we’re going to go on for an hour or so. Then, somewhere along the line I would tell you what I’m going to charge.

However, as kind of special to Heat Treat Today, if any of you want to call me and say, “Rick, this isn’t going to take too long, but I don’t know where find this, I don’t know where to navigate. What did you mean about this?” No charge! Just call me and ask me. If it’s not too long, done! We’ll take care of it right up front.

Bethany Leone: Nice. Thank you!

Is there an email address or a website that they could visit?

Rick Kaletsky: In the end, the most important thing is going to be the phone. There are times when I get an email, and they’ll say something like, “When’s a good time to talk next week?” If you call me now, I’d either say, “If you can’t talk now, let’s set it up right now.” I’m not going to send you an Excel sheet and tell you what blocks I have available. I can maybe give you the answer right now or if you want to do it tomorrow, we’ll have a conversation. To have a lot of back and forth and emails, no. If we’re on the phone, we take care of it. Efficiency.

Bethany Leone: If there’s anything I’ve learned about Rick in the past time that we’ve been able to talk is you like to get things done NOW. And you’re helpful. If anyone is listening -- please take advantage. This is really great of Rick to be offering this to us. Give him a call. He’s a great explainer and great teacher, but also has a wealth of knowledge.

Rick Kaletsky: I appreciate the opportunity to do this. I hope it’s helpful.

Staying Safe on the Floor: 8 Safety Tips for Heat Treaters

OCWe've assembled some of the top 101 Heat Treat Tips that heat treating professionals submitted over the years into today’s original content. Read on for 8 tips that will keep you and your team safe!

4 Reasons Not to Overlook Combustion System Maintenance

Anyone who has operated a direct fired furnace, especially one that relies on pressure balance ratio regulators for ratio control, knows that regular tuning is needed to keep the process running with the proper air to fuel ratio.

Here are 4 reasons not to skip regular combustion system tuning:

  1. It can cost you money: Operating with more air than needed will reduce your furnaces efficiency and require you to burn more fuel. Conversely, operating air deficient, unless necessary for the process, results in unburned fuel being released with the exhaust gasses. In most cases the unburned fuel going up your stack is energy that you paid for.
  2. It can decrease product quality and yield:  For many ferrous metals too much excess air will result in excess scale formation at high processing temperatures. On the contrary other materials such as titanium need to be processed with excess air to prevent Hydrogen pickup.
  3.  It can reduce your furnace’s reliability:  The burners on your direct fired furnace will have a defined range of acceptable air to fuel ratios for proper operation. If your system wanders outside of this range, which can be fairly tight with today’s ultra-low NOx burners, you could start to see flame failures that result in unplanned shutdowns.
  4. It can be a safety hazard: Apart from the possibility of causing burner instability, running with too little air will increase CO emissions. Unless your furnace is designed to safety exhaust CO you could end up exposing personnel working near your furnace to this deadly gas.

Alarm Your Eye Fountains & Deluge Showers

For emergency eye fountains and deluge showers, I recommend that each plumbed unit be equipped with an audio and visual alarm on a spring-loaded bypass. The purpose of the alarm is to alert others of the emergency. It is important that employees promptly respond to assist the employee who has been sprayed, splashed, or otherwise contacted by the dangerous substances. The bypass allows employees to easily test the units without setting off the alarm. If there is no bypass, employees might be reluctant to conduct the test, feeling it takes too much effort to alert all relevant persons that there is a test. As a result, an inadequacy of the flushing system could go undetected. With the bypass on a spring-loaded system, the person who conducts the test cannot fail to reset the alarm; it is reset automatically.

(Rick Kaletsky)


Gauge Those Gauges

It is quite common, in my experience during inspections, to find gauges that are missing bezels or have severely broken bezels. This can be a hazard if the stylus or general mechanism is damaged. I have found stuck styluses. A false reading may be given. Such a reading may result (for example) in an employee boosting air pressure, or the level of liquid in a tank or a temperature, far beyond the safe limit. I have also noted gauges where the stylus had been broken-off, and an employee merely made an assumption of what the proper “numbers” were. When conducting preventive maintenance tasks, check those gauges and replace missing or damaged bezels.

Check Your Quench Oil

Safety – Performance – Oxidation

Safety

  • Water content should not exceed a maximum of 0.1% in the quench oil.
  • Flash point should be checked to ensure no extraneous contamination of a low flash point material (i.e. kerosene) has been introduced into the quench tank.

Performance

  • Cooling curve analysis or GM Quenchometer Speed should be checked to confirm the quench oil is maintaining its heat extraction capabilities. Variances in heat extraction capabilities could possibly lead to insufficient metallurgical properties.

Oxidation

  • TAN (total acid number) and Precipitation Number should be checked to ensure the quench oil is thermally and oxidatively stable. Oxidation of the quench oil can lead to staining of parts and possible changes in the heat extraction capabilities.
  • Sludge content should be checked . . . filter, filter, filter . . . sludge at the bottom of the quench tank can act a precursors for premature oxidation of the quench oil.

Work with your quench oil supplier on a proactive maintenance program . . . keep it cool . . . keep it clean . . . keep it free of contamination to extend the life of your quench oil.

(Quaker Houghton)


Compliance Issues? Try On-Site Gas Generation

On-site gas generation may help resolve compliance issues. Growth and success in thermal processing may have resulted in you expanding your inventory of reducing atmosphere gases. If you are storing hydrogen or ammonia for Dissociated Ammonia (DA), both of which are classed by the EPA as Highly Hazardous Materials, expanding gas inventory can create compliance issues. It is now possible to create reducing gas atmospheres on a make-it-as-you-use-it basis, minimizing site inventory of hazardous materials and facilitating growth while ensuring HazMat compliance. Modern hydrogen generators can serve small and large flow rates, can load follow, and can make unlimited hydrogen volumes with virtually zero stored HazMat inventory. Hydrogen is the key reducing constituent in both blended hydrogen-nitrogen and DA atmospheres—hydrogen generation (and optionally, nitrogen generation) can be used to provide exactly the atmosphere required but with zero hazardous material storage and at a predictable, economical cost.

Use Fall Protection Systems to Reduce Construction-Related Falls

Most equipment used for thermal processing stands well over 10 feet tall and has the capacity to hold or process over 60 tons of molten metal. During refractory installation, repair and maintenance of this large equipment, refractory professionals often find themselves raised atop platforms, scaffolding, decking and work stations. Due to the fact that refractory employees regularly work at elevated heights, it is crucial to keep them safe from fall-related injuries, as well as to ensure the job site is free of safety violations. To accomplish this goal, it is essential to understand the hazards of falls and know the Occupational Safety and Health Administration (OSHA) rules.

According to OSHA, in 2017, almost 42% of all construction worker related deaths were attributed to falls. Thousands more were injured. Fall Protection infractions (OSHA 29 CFR 1926.501) also topped OSHA’s 2018 list of the Top 10 Safety Violations for the eighth consecutive year.

Incidents involving falls frequently involve a variety of factors, however, a common thread running through most is the absence of fall protection equipment. Even if you’re Nik Wallenda, the high wire aerialist of the famed Flying Wallendas family, OSHA requires protection when working on refractories at heights of six feet above a lower level:

Handrails, Guardrails and Toe-boards: serve as barriers between the employee and an open edge. Midrails or screens need to be installed between the top of the guardrail and the walking or working surface to prevent falls.

Personal Fall Arrest Systems: provide employees with an individual form of fall protection. For example, a body harness connected to a lanyard or retractable line secured to a fixed anchor. These types of systems are designed to go into action before contact with any lower level.

Personal Fall Restraint Systems: prevent employees from reaching the edge where a fall hazard is likely to occur. It tethers a worker in a manner that will not allow a fall of any distance. This system is comprised of a body belt or body harness, an anchorage, connectors, and other necessary equipment.

As a second line of defense or where fall prevention systems are not practical, for instance roof work, a warning line system consisting of ropes, wires, or chains is an approved solution if it is at least 6 feet from open edges around all sides of the work area. Fixed barriers can also be installed to prevent employee access to dangerous areas.

To address any hazardous areas that may have floor openings, color-coded covers should be used and marked with the word “Hole”. Covers should be secured tight to prevent workers from falling through floors or elevated areas.

OSHA clearly states employer requirements. OSHA mandates employers train workers on how to use personal fall protection equipment and how to work in hazardous situations. Employers must also assess the workplace to determine if walking or working surfaces have the necessary strength and structural integrity to safely support workers.

Before any work begins, conduct a hazard assessment to develop a comprehensive fall protection plan, to manage hazards and focus employee attention on prevention. Falls cause deaths and numerous serious injuries each year, many of which are preventable. Maintain the highest safety standards on your job site by installing or using fall protection systems – not all of us can be as sure footed as Nik Wallenda.

Container Clarity Counts!

Assure that container label wording (specifically for identifying chemical contents) matches the corresponding safety data sheets (SDS). Obvious? I have seen situations where the label wording was legible and accurate and there was a matching safety data sheet for the contents, but there was still a problem. The SDS could not be readily located, as it was filed under a chemical synonym, or it was filed under a chemical name, whereas the container displayed a brand name. A few companies label each container with (for instance) a bold number that is set within a large, colored dot. The number refers to the exact corresponding SDS.

A Products Eye View in the CAB Furnace Using Optical Profiling

Ever wished you could see what truly happens to your product as it travels through your conveyorized CAB furnace? Well now you can! Thru-process Optical profiling is similar to temperature profiling but instead of measuring the temperature of the product the system records a high-resolution video of the products journey through the furnace. It’s like running your car “Dash Cam” but through the furnace at over 1000°F. The resulting video “Optical Furnace Profile” shows process engineers so much more about how their process is operating without any need to stop, cool and dismantle the furnace. This allows safe routine furnace inspection without any of the problems of costly lost production and days of furnace down time. From the video evidence, the root cause of process problems, possibly already highlighted by running the temperature profile system, can be identified accurately and efficiently. Furnace structural damage or faulty furniture such as recirculating fans, control thermocouples or heater elements can be detected. Buildup of unwanted flux within the furnace can be monitored allowing accurate service and clean down schedules to be planned preventing future unplanned costly line stoppages. Damage or distortion of the conveyor belt compromising the safe smooth transfer of product through the furnace can be isolated with accuracy helping reduce corrective action turnaround times.

Induction Hardening Cast Iron

Induction hardening of cast irons has many similarities with hardening of steels; at the same time, there are specific features that should be addressed. Unlike steels, different types of cast irons may have similar chemical composition but substantially different response to induction hardening. In steels, the carbon content is fixed by chemistry and, upon austenitization, cannot exceed this fixed value. In contrast, in cast irons, there is a “reserve” of carbon in the primary (eutectic) graphite particles. The presence of those graphite particles and the ability of carbon to diffuse into the matrix at temperatures of austenite phase can potentially cause the process variability, because it may produce a localized deviation in an amount of carbon dissolved in the austenitic matrix. This could affect the obtained hardness level and pattern upon quenching. Thus, among other factors, the success in induction hardening of cast irons and its repeatability is greatly affected by a potential variation of matrix carbon content in terms of prior microstructure. If, for some reason, cast iron does not respond to induction hardening in an expected way, then one of the first steps in determining the root cause for such behavior is to make sure that the cast iron has not only the proper chemical composition but matrix as well.

14 Quench Oil Selection Tips

Here are a few of the important factors to consider when selecting a quench oil. 

  1. Part Material – chemistry & hardenability 
  2. Part loading – fixturing, girds, baskets, part spacing, etc. 
  3. Part geometry and mass – thin parts, thick parts, large changes in section size 
  4. Distortion characteristics of the part (as a function of loading) 
  5. Stress state from prior (manufacturing) operations 
  6. Oil type – characteristics, cooling curve data 
  7. Oil speed – fast, medium, slow, or marquench  
  8. Oil temperature and maximum rate of rise 
  9. Agitation – agitators (fixed or variable speed) or pumps 
  10. Effective quench tank volume 
  11. Quench tank design factors, including number of agitators or pumps, location of agitators, size of agitators, propellor size (diameter, clearance in draft tube), internal tank baffling (draft tubes, directional flow vanes, etc.), flow direction, quench elevator design (flow restrictions), volume of oil, type of agitator (fixed v. 2 speed v. variable speed), maximum (design) temperature rise, and heat exchanger type, size, heat removal rate in BTU/hr & instantaneous BTU/minute.
  12. Height of oil over the load 
  13. Required flow velocity through the workload 
  14. Post heat treat operations (if any)

How to Achieve a Good Braze

In vacuum brazing, be certain the faying surfaces are clean, close and parallel. This ensures the capillary action needed for a good braze.

A good brazing filler metal should:

  1. Be able to wet and make a strong bond on the base metal on which it’s to be applied.
  2. Have suitable melt and flow capabilities to permit the necessary capillary action.
  3. Have a well-blended stable chemistry, with minimal separation in the liquid state.
  4. Produce a good braze joint to meet the strength and corrosion requirements.
  5. Depending on the requirements, be able to produce or avoid base metal filler metal interactions.

Pay Attention to Material Chemistry

When trying to determine a materials response to heat treatment, it is important to understand its form (e.g., bar, plate, wire, forging, etc.), prior treatments (e.g. mill anneal, mill normalize), chemical composition, grain size, hardenability, and perhaps even the mechanical properties of the heat of steel from which production parts will be manufactured. The material certification sheet supplies this basic information, and it is important to know what these documents are and how to interpret them.

Certain alloying elements have a strong influence on both the response to heat treatment and the ability of the product to perform its intended function. For example, boron in a composition range of 0.0005% to 0.003% is a common addition to fastener steels. It is extremely effective as a hardening agent and impacts hardenability. It does not adversely affect the formability or machinability. Boron permits the use of lower carbon content steels with improved formability and machinability.

During the steelmaking process, failure to tie up the free nitrogen results in the formation of boron nitrides that will prevent the boron from being available for hardening. Titanium and/or aluminum are added for this purpose. It is important, therefore, that the mill carefully controls the titanium/nitrogen ratio. Both titanium and aluminum tend to reduce machinability of the steel, however, the formability typically improves. Boron content in excess of 0.003% has a detrimental effect on impact strength due to grain boundary precipitation.

Since the material certification sheets are based on the entire heat of steel, it is always useful to have an outside laboratory do a full material chemistry (including trace elements) on your incoming raw material. For example, certain trace elements (e.g. titanium, niobium, and aluminum) may retard carburization. In addition, mount and look at the microstructure of the incoming raw material as an indicator of potential heat treat problems.

Aqueous Quenchant Selection Tips

Determine your quench: Induction or Immersion? Different aqueous quenchants will provide either faster or slower cooling depending upon induction or immersion quenching applications. It is important to select the proper quenchant to meet required metallurgical properties for the application.

  1. Part material: Chemistry and hardenability are important for the critical cooling rate for the application.
  2. Part material: Minimum and maximum section thickness is required to select the proper aqueous quenchant and concentration.
  3. Select the correct aqueous quenchant for the application as there are different chemistries. Choosing the correct aqueous quenchant will provide the required metallurgical properties.
  4. Review selected aqueous quenchant for physical characteristics and cooling curve data at respective concentrations.
  5. Filtration is important for aqueous quenchants to keep the solution as clean as possible.
  6. Check concentration of aqueous quenchant via kinematic viscosity, refractometer, or Greenlight Unit. Concentration should be monitored on a regular basis to ensure the quenchant’s heat extraction capabilities.
  7. Check for contamination (hydraulic oil, etc.) which can have an adverse effect on the products cooling curves and possibly affect metallurgical properties.
  8. Check pH to ensure proper corrosion protection on parts and equipment.
  9. Check microbiologicals which can foul the aqueous quenchant causing unpleasant odors in the quench tank and working environment. If necessary utilize a biostable aqueous quenchant.
  10. Implement a proactive maintenance program from your supplier.

Container Clarity Counts!

Assure that container label wording (specifically for identifying chemical contents) matches the corresponding safety data sheets (SDS). Obvious? I have seen situations where the label wording was legible and accurate and there was a matching safety data sheet for the contents, but there was still a problem. The SDS could not be readily located, as it was filed under a chemical synonym, or it was filed under a chemical name, whereas the container displayed a brand name. A few companies label each container with (for instance) a bold number that is set within a large, colored dot. The number refers to the exact corresponding SDS.

Oil and Water Don’t Mix

Keep water out of your oil quench. A few pounds of water at the bottom of an IQ quench tank can cause a major fire. Be hyper-vigilant that no one attempts to recycle fluids that collect on the charge car.

(Combustion Innovations)


Dirt In, Dirt Out!

Parts going into the furnace should be as clean as possible. Avoid placing parts in the furnace that contain foreign object debris (FOD). FOD on work surfaces going into the furnace will contaminate the furnace and the parts themselves. Dirty work in, dirty work out. FOD comes in many forms. Most common: oil, grease, sand in castings or grit blasting operations, and metal chips that generally originate from the manufacturing process before the parts are heat treated. It could also be FOD from the shipping process such as wood or plastic containers used to ship the parts.

(Solar Manufacturing)


Remove Particulates

Adding a strong magnetic filter in line after the main filtration system is an effective way to remove fine, metallic particulates in an aqueous quench system.

(Contour Hardening, Inc.)


Seal Away Dirt or Dusty Environments

Use a sealed enclosure or alternative cooled power controllers for dirty and dusty environments. For heavy dirt or dusty environments, a sealed cabinet with air conditioning or filters is recommended. Alternatively, select a SCR manufacturer that offers external mount or liquid cooled heatsinks to allow you to maintain a sealed environment in order to obtain maximum product life.

(Control Concepts)


Copper as a Leak Check

If maintaining dew point is a problem, and it’s suspected that either an air or water leak is causing the problem, run a piece of copper through the furnace. Air will discolor the copper; water will not.

(Super Systems, Inc.)


Oxygen Contamination Sources

A common source of oxygen contamination to vacuum furnace systems is in the inert gas delivery system. After installation of the delivery lines, as a minimum, the lines should be pressurized and then soap-bubble tested for leaks. But even better for critical applications is to attach a vacuum pump and helium leak detector to these lines with all valves securely closed, pull a good vacuum, and helium leak check the delivery line system. Helium is a much smaller molecule than oxygen and a helium-tight line is an air-tight line. Also, NEVER use quick disconnect fittings on your inert gas delivery system to pull off inert gas for other applications unless you first install tight shut-off valves before the quick disconnect. When the quick disconnect is not in use, these valves should be kept closed at all times. (Though the line is under pressure, when you open a back-fill valve to a large chamber, the line can briefly go negative pressure and pull in air through a one-way sealing quick disconnect valve.)

(Grammer Vacuum Technologies)


Container Clarity Counts!

Assure that container label wording (specifically for identifying chemical contents) matches the corresponding safety data sheets (SDS). Obvious? I have seen situations where the label wording was legible and accurate and there was a matching safety data sheet for the contents, but there was still a problem. The SDS could not be readily located, as it was filed under a chemical synonym, or it was filed under a chemical name, whereas the container displayed a brand name. A few companies label each container with (for instance) a bold number that is set within a large, colored dot. The number refers to the exact corresponding SDS.

(Rick Kaletsky, Safety Consultant)


Discolored Part—Who’s to Blame?

If your parts are coming out of the quench oil with discoloration and you are unsure if it is from the prewash, furnace, or oil quench, you can rule out the quench if the discoloration cannot be rubbed off. Check this before the part is post-washed and tempered.

Other possible causes:

  • Can be burnt oils as parts go through the quench door flame screen
  • Poor prewash
  • Furnace atmosphere inlet (particularly if it is drip methanol)

Heat Treat Tips: The Essential Three

One of the great benefits of a community of heat treaters is the opportunity to challenge old habits and look at new ways of doing things. Heat Treat Today’s 101 Heat Treat Tips is another opportunity to learn the tips, tricks, and hacks shared by some of the industry’s foremost experts.

For Heat Treat Today’s latest round of 101 Heat Treat Tipsclick here for the digital edition of the 2019 Heat Treat Today fall issue (also featuring the popular 40 Under 40).

Today’s tips are the 1 – 2 – 3! They come to us from Dry Coolers with a word on cooling system growth capability; Bloom Engineering Company Inc. on the importance of careful spending; and Rick Kaletsky, Safety Consultant about clear content labeling.


Heat Treat Tip #1

Buy a Cooling System Capable of Growth

Plan for future growth. It is more cost effective to provide additional capacity while equipment is being installed. Simple planning for the addition of future pumps (e.g. providing extra valved ports on tanks) and space for heat transfer equipment (e.g. pouring a larger pad or adding extra piers) can save considerable money down the road with little upfront expenditure. Consider installing one size larger piping for the main distribution supply and return; if this is not possible, make sure you can add an additional piping run on the hangers you will install now. Above all, be sure to include all necessary drains, vents, isolation valves, and plenty of instrumentation. These items are critical aids in maintenance, troubleshooting, and future system expansion. (Dry Coolers)

Thinking about future growth will help you choose the right cooling system.


Heat Treat Tip #2

Never Go Cheap on These Two Things

There are 2 things in life you should never go cheap on: Toilet paper and combustion equipment! When upgrading or looking at new systems, spend the money to do it right. Designing on the cheap will only lead to operational and maintenance headaches. And trying to reuse the ancient artifacts when upgrading just to save a buck will cost you 10x that down the road. You don’t have to break your budget to do a quality job! (Bloom Engineering Co. Inc.)


Heat Treat Tip #3

Container Clarity Counts!

Assure that container label wording (specifically for identifying chemical contents) matches the corresponding safety data sheets (SDS). Obvious? I have seen situations where the label wording was legible and accurate and there was a matching safety data sheet for the contents, but there was still a problem. The SDS could not be readily located, as it was filed under a chemical synonym, or it was filed under a chemical name, whereas the container displayed a brand name. A few companies label each container with (for instance) a bold number that is set within a large, colored dot. The number refers to the exact corresponding SDS. (Rick Kaletsky, Safety Consultant)

A Tour of Common Hazards in the Heat Treat Industry

Rick Kaletsky, Owner, Safety Consultant

Safety is a concern to all industries, but it’s of paramount importance for the aerospace manufacturing sector. Join us on this whirlwind tour of a heat treat shop from the perspective of an industry safety consultant, Rick Kaletsky. Rick’s a funny guy, but don’t let that detract from the critically important information he has to share. Rick Kaletsky is an MTI OSHA Safety Consultant and the author of the popular book, OSHA Inspections: Preparation and Response, 2nd Edition.

This column is being supplied courtesy of the Metal Treating Institute and was first published in the Heat Treat Today Aerospace magazine in March 2019.


With all of the bright and shiny new gadgets and technology in the heat treat industry, it’s easy to overlook the wealth of the “same old” classic hazards, which may not have been properly dealt with in the shop. It is critical to address these basic (often severe) risks/violations rather than be distracted by trying to identify new-to-the-forefront issues. Please note that this list is surely not all-inclusive. I’ll make this concise as we tour the shop and highlight areas that demand attention.

Let’s take a look:

  • Are you still allowing obstacles to impede immediate access to exits, fire extinguishers, electrical disconnects, and emergency eye fountains?
  • Are you permitting unguarded (or improperly guarded) power transmission equipment, highlighted by chain drives, belt drives, couplings, and gears?
  • Have you adequately guarded fan blades?
  • Are you adhering to the (chemical) hazard communication program— especially the labeling, safety data sheets, and
    training? (Also, don’t forget the Globally Harmonized System.)
  • Is the lockout/tagout program (relating to unexpected energization and release of stored energy) sufficient— attaining ZES (zero energy state addressing electrical, mechanical, pneumatic, hydraulic, spring, thermal, steam, gravity+), only one “available” key per personal lock, machine-specific procedures, and more?
  • What kind of permit-required confined-space program have you implemented—a detailed, super priority, tackling matters of oxygen deficiency, vapor ignition, entrapment, and so on, with a fully integrated plan including (but not limited to) space identification, permit system, calibrated instrumentation, attendants, and non-exposed rescuers?

All set now? WAIT! There’s more that is routinely violated on a regular basis. These items above, and more to follow, are not simply matters of technical non-compliance with the law of the land. They are scenarios waiting to ambush workers and leave them with burns or worse (from fire, explosion, and electrical sources), mangled digits and limbs, blindness, lung damage, and many other examples of preventable misery.

Abatement can be motivated by a desire to avoid “breaking the law and paying the price.” It can be motivated by ethics and the sincere “touchy feely” desire to “do the right thing.” Yet it can also be motivated by a company’s knowledge that employee protection is good business, with very tangible, financial results. The cost of occupational injuries and illnesses can decimate your profit line far more than direct medical costs. It is worth considering all of the follow-up medical bills, cleanup, overtime, downtime, insurance rate increases, and much, much more, not to mention the enhanced OSHA penalties.

Pardon the diversion; now for a look at some more key questions:

  • Is heat stress considered to be a very real concern (and met head-on as an occupational hazard) rather than viewed as a mere matter of degrees of comfort?
  • Has there been a full assessment of personal protective equipment needs?
  • Is safety-toed footwear required, as determined by such an assessment?
  • How about eye protection (consider different forms for different hazards), hand protection (again, particular types for particular risks), hearing protection, flame-resistant/retardant clothing, and whatever else is brought to light by way of a thorough assessment considering each task to be performed?
  • Are the extinguishers conspicuous, fully charged, and professionally tested on a timely basis?
  • Who is expected to use the extinguishers, and have those employees been “hands-on” trained?
  • Are compressed gas cylinders well-secured, capped (where designed to be), and properly separated (oxygen from fuel gas, in storage)?

Have I offered enough tips? No? Okay, here are just a few more points to ponder:

  • Are electrical cords in good condition, without (for instance) stripped/cut/burned insulation, damaged/missing grounding prongs, or similar damage? (Remember that portable electrical tools can be double-insulated, as an alternative to grounding.)
  • Is there accurate, unambiguous, easy-to-read labeling on disconnects, breakers, controls, and so on?
  • If there are breaker slots without breakers, are those spaces filled with blanks?
  • Are electrical boxes and similar apparatus equipped with approved covers?
  • Are forklift trucks and similar vehicles properly maintained, with emphasis on steering, brakes, horn, tires, overhead guard, and fork movement reliability; are all operators suitably trained?
  • How about the elimination or deep mitigation of trip and slip hazards?
  • What have you done (including by engineering means and specific training) to decrease exposure to ergonomic hazards, especially regarding backs?

There’s always more that can be done to improve safety and minimize risk in the shop, and it’s usually something easily overlooked in regular safety checks that turns up flagged in a review. But don’t let the procedure blind you to the most important reason we stress safety in the shop: the welfare of our employees.

Heat Treat Tip #3

Unclear labeling of chemical materials creates a hazardous situation.

Container Clarity Counts!

Assure that container label wording (specifically for identifying chemical contents) matches the corresponding safety data sheets (SDS). Obvious? I have seen situations where the label wording was legible and accurate and there was a matching safety data sheet for the contents, but there was still a problem. The SDS could not be readily located, as it was filed under a chemical synonym, or it was filed under a chemical name, whereas the container displayed a brand name. A few companies label each container with (for instance) a bold number that is set within a large, colored dot. The number refers to the exact corresponding SDS.


Heat Treat Tip #60

Emergency eye fountains are critical, but human assistance goes far.

Alarm Your Eye Fountains & Deluge Showers

For emergency eye fountains and deluge showers, I recommend that each plumbed unit be equipped with an audio and visual alarm on a spring-loaded bypass. The purpose of the alarm is to alert others of the emergency. It is important that employees promptly respond to assist the employee who has been sprayed, splashed, or otherwise contacted by the dangerous substances. The bypass allows employees to easily test the units without setting off the alarm. If there is no bypass, employees might be reluctant to conduct the test, feeling it takes too much effort to alert all relevant persons that there is a test. As a result, an inadequacy of the flushing system could go undetected. With the bypass on a spring-loaded system, the person who conducts the test cannot fail to reset the alarm; it is reset automatically.


Heat Treat Tip #81

Gauge Those Gauges

It is quite common, in my experience during inspections, to find gauges that are missing bezels or have severely broken bezels. This can be a hazard if the stylus or general mechanism is damaged. I have found stuck styluses. A false reading may be given. Such a reading may result (for example) in an employee boosting air pressure, or the level of liquid in a tank or a temperature, far beyond the safe limit. I have also noted gauges where the stylus had been broken-off, and an employee merely made an assumption of what the proper “numbers” were. When conducting preventive maintenance tasks, check those gauges and replace missing or damaged bezels.
