Today’s best of the web features a video demonstration from the Crafts Center of North Carolina State University (NCUS), which recently released the results of the trial application of high-temperature ceramic coatings to the linings of kilns used at the center.

Cone 10 Gas Reduction Car Kiln at North Carolina State University Crafts Center

Jennifer Siegel Clay, studio manager at NCUS Crafts Center, summarizes the process of lining two kilns with coatings from ITC Coatings, which produces high-temperature ceramic coatings for kilns, forges, furnaces, ovens and metal equipment, first developed in 1980 in Alliance, Ohio, by Feriz Delkic, a ceramic engineer who was running his own pottery business at the time. ITC Coatings provides solutions to problems faced by industries with heat treatment processes such as steel, power generation, and petrochemical, as well as ceramic artists and home hobbyists all over the world.

The first kiln, a 50 cubic foot Cone 10 gas reduction car kiln was coated with ITC 100HT. The outside surface temp was reduced by 30+ dF and the firing time was reduced by 1 hour (28 hour firing). The second kiln, a Barrel Raku kiln, was coated with ITC 296A. The outside surface temperature was reduced by 50+ degrees F, firing time was reduced by half, and gas consumption was reduced by greater than one third. Siegel Clay refers to it as “armor for your kilns.”

There are several industry veterans who have helped us procure content that appeals to and serves our in-house heat treating audience. I’d like to express a special thanks to:

I am also thankful to one other unnamed company who has been very supportive and patient as we’ve built Heat Treat Today. They’ve done so in large part quite sacrificially. I am sincerely indebted to this company and especially to the top management team there for their moral and selfless support.

I’d also like to thank the Heat Treat Today team:

  • Mary Glenn, also known as the lovely and gracious Mrs. Glenn (my wife), who has served in multiple roles during the last two years — editor and audience development among them. Thank you, Mary, for your invaluable support!
  • Brandon Glenn, who is not my son even though he looks very much like he could be. Brandon has been responsible for all the website development and e-newsletter designs, and it is he who makes sure all the correct ads are running on the website each month. (For the record, he’s my brother’s son!)
  • Laura Miller joined our team a year ago as a contributing editor and has very quickly become a cornerstone of our efforts. Laura is the one who provides the daily content. She’s doing a wonderful job. Thank you, Laura.
  • Jonathan Condon, a very talented young man who attended the same Presbyterian church and does a great job with our Heat Treat Radio podcasts. Jonathan is finishing up college and finds time to produce our podcasts very proficiently.
  • Jonathan’s mother, Kelly Condon, recently joined the team helping with billing and other administrative work. (not pictured)

Doug Glenn, Publisher

Heat Treat Today would not be possible without all of the above advertisers, industry veterans, and team members. A big 2nd anniversary “thank you” to all. And it should not go without saying that all of us at Heat Treat Today are thankful to God for his blessings as we’ve navigated these first two years. Anything good we’ve done is really His fault!! Any mistakes: our fault!

Two years ago there was no Heat Treat Today. Two years ago there was no Heat Treat Radio. Two years ago, there was no Heat Treat Shop. Who knows what the years ahead will bring? Lord willing, we’ll continue to grow in our usefulness to the industry, and more and more in-house heat treaters will find the content and manner of delivery of that content helpful. The fact is, we have a LOT of ideas that we’re currently working on. Keep your eyes on Heat Treat Today. There should be more good stuff coming in the future.

With sincere thanks,

MTI Partners with Staffing Firm Specializing in Transferring Military Vets into Workplace

From the Editor: May is Military Appreciation Month, and Monday, May 28, 2018, is Memorial Day, on which we are called to remember those who died in active military service. The staff at Heat Treat Today is thankful for those who made that great sacrifice and grateful to be able to honor those who have served. We salute our military heroes past and our veterans with this post about the heat treat industry and military staffing. Heat Treat Today will not publish on Monday, May 28, 2018.


Finding good, qualified workers in today’s labor pool is the critical issue facing any industry.

The workers are just not in the marketplace.  To help MTI members win the battle for finding qualified people, MTI signed a partnership with the largest military veteran staffing firm in America, Bradley-Morris, Inc (BMI).  Bradley-Morris is a leader in helping transfer military veterans back into the corporate and manufacturing workplace.

A few reasons companies may want to take advantage of this very valuable new service, according to MTI:

  • Every year over 200,000 military veterans transfer out of the military into the public workspace.
  • 72% are under the age of 30.
  • Geography is not an obstacle.  Relocation assistance costs are covered by the government for many transitioning military persons.
  • Bradley Morris is the leading military staffing firm for placing veterans into civilian jobs upon separation.
  • MTI members receive a special, pre-negotiated, below market placement fee.

MTI is the Metal Treating Institute, a non-profit trade association that represents the largest network of commercial heat treaters in the world with members in 40 states and 8 countries.  MTI’s network services every major industry and performs every heat treating process required. Heat Treat Today is a proud member of MTI.

For more information on MTI’s partnership with Bradley-Morris, Inc, particularly for links to case studies on the successful hiring of military personnel and other resources related to the process of hiring military veterans, visit here: MTI: Military Staffing

Tester Detects, Determines Temperature Boundaries for Heat-Treated NiTi Martensite-to-Austenite

A new testing device has been introduced by an Israeli precision laser specialist group that can determine the Start and Finish Af (martensite-to-austenite transformation) temperatures for each of several devices, of different shapes at the same time.

The noncontact Af tester (NCAT), a novel bent and free-recovery device, was recently unveiled by ANV Laser of Petah Tikva, Israel.

The NCAT’s proprietary image processing software automatically detects the boundary of each of the fully annealed or heat-treated nickel titanium items placed in the chilled test tray.

Prior to the testing process, the nickel-titanium test specimen is cooled to its nominally fully martensitic phase, then is deformed by bending, and finally is heated to its fully austenitic phase while the motion (recovery) of the specimen is measured and plotted against the temperature.

The NCAT’s proprietary image processing software automatically detects the boundary of each of the fully annealed or heat-treated nickel titanium items placed in the chilled test tray. In the user-friendly graphic interface, the tester easily deletes any non-item artifacts that were detected, and then chooses – per object — the area detection method for the test, such as inscribed or described circle, parallel lines, object boundary, and so on.

The tester then defines, for each object, the minimum and maximum boundaries for Area (to be plotted on the Y axis) and Temp (to be plotted on the X axis). The tester can also determine the rate of heating that will be generated by the NCAT’s unique heating mechanism. When satisfied with all parameters, the tester initiates the test and an Area/Temp graph is plotted for each object.

When the temperature reaches the user-defined end-temperature, the test stops automatically. The test plot for each item can be saved as a report that shows its Area/Temp graph and the calculated StartAF and FinishAF temperatures.

Nico Schmitz, Christian Schwotzer, and Herbert Pfeifer with the Department for Industrial Furnaces and Heat Engineering (IOB) in Germany have collaborated on an analysis of metallic recirculating radiant tubes, their purpose in the heat treating process, and their design and installation. In particular, the authors, with access to a furnace-equipped pilot plant operated by IOB, investigate the factors that affect tube productivity and contribute to tube failures. They have reported on these findings in an exclusive paper published at heat processing online, the official publication of the European Committee of Industrial Furnace and Heating Equipment Association (CECOF).

An excerpt:

“It is common to assume a homogeneous temperature distribution for construction calculations. In real operation, inhomogeneous temperature distributions occur. The temperature gradients induce thermal stresses that can substantially influence the lifetime of the tubes. In addition to that, higher furnace temperatures come along with an increasing thermal load.”
