A Russian manufacturer of hydraulic cutting tools and rescue and emergency equipment recently extended its range of services by offering commercial heat treatment through its newly created subsidiary, TVN2.
SPRUT expanded its operation with a BMI double chamber vacuum furnace (B64TH for oil and gas quenching) and a second furnace for tempering and low-pressure nitriding (B54RN). This led to the launch of TVN2 to carry out the vacuum technology heat treatments, offering repeatability of results and giving the company control of the manufacturing process. With its own metallurgical laboratory on site, SPRUT, through TVN2, is able to offer hardness and microstructure analyses as additional services.
Following several months of nothing but relatively good news, this month’s IHEA Executive Economic Summary Report shows some numbers dipping. As Chris Kuehl, the economist behind the report, states in his monthly in-depth analysis, “This month there is good news in bad data and some bad news in the good data. It is not always about whether an index is climbing this month or not. Sometimes it is the overall trend line and how it compares to what it might have been some months ago.”
Auto and light truck sales continue to be strong.
Every month, Dr. Kuehl, through IHEA, provides not only raw data that is of specific interest to the heat treating industry, but he also provides insightful analysis of what the numbers mean and why readers should care.
Dr. Chris Kuehl, economic analyst for IHEA, prepares the monthly IHEA Economic Trends Index.
The April report showed an increase in roughly half of the index numbers, including a surprisingly strong automobile and light truck sales index which, according to Kuehl, “continues to shock analysts as there is an assumption that the market is already saturated. It seems not to be the case as the consumer still has a desire for new wheels and if the current hike in gas prices accelerates there may soon be a new desire for those fuel sippers.”
Steel consumption continues to be weak.
Along with auto and truck sales, some of the other indices that also continued to climb were industrial capacity utilization, capital expenditures, and durable goods shipments.
Falling indices included the purchasing managers index, new home starts, and steel consumption.

A German heat treat aftermarket supplier recently reached a cooperation with a European heat treating manufacturer for the production and distribution of heat treat systems for precision fine casting industries.
Linn High Therm GmbH and SAFED Suisse SA, a company of the Aichelin Group, announced the joint project in early 2018, wherein Linn High Therm GmbH will license the production of smaller heat treatment systems for watch, jewelry, and microsystems technology from SAFED’s product range. The agreement states that SAFED will take over the distribution of these products as well as the distribution and service of the products of Linn High Therm GmbH in Switzerland, France, Italy, and partly Germany through the existing sales and service network.
Both companies are experienced in the development and construction of electrically heated heat treatment plants. Linn High Therm GmbH specializes in the production of industrial and lab furnaces/ kilns, microwave furnaces, sample preparation units for spectroscopy, induction heating systems, precision fine casting systems and customer-specific systems. SAFED Suisse SA, based in Delémont, Switzerland, provides installations for the watchmaking and micromechanical industries.

Heat treating plays a critical role in the making of a mold base, notes an Austrian manufacturer of standard parts for mould bases and die sets in a recent process profile in ETMM-online.
An excerpt:
"Heat-treat[ing] all steel plates for stress relief . . . at approximately 580°C [1076°F] for 24 hours . . . creates optimal conditions for low-deformation processing of parts. . . . With stress-relieving heat treatment, the tension in the material is minimized without changes to the microstructure or strength. This is a great advantage during subsequent machining. If there was still tension in the material, it would, for example, cause deformation during sawing or milling. During stress-relieving, it is important to heat the plates slowly and consistently and then maintain this temperature for six hours."
With the recent reopening of its drawing mill in Hallstahammar, Sweden, a leading supplier of industrial heating technology and resistance materials expects to meet an increased global demand for heating, resistance and thermocouple wire.
Nicklas Nilsson, president at Kanthal
Kanthal, which is part of the Sandvik Group, recently expanded its capacity by reopening its drawing mill, which includes a new production line designed in a flexible way to secure a sustainable and cost-effective wire drawing.
“We want to support our customers to grow and stay competitive. To be able to do this, we must ramp up our production of Kanthal® wire to secure short and reliable lead times,” said Christoffer Saarnio, global supply chain manager (shown above). “With the new production line, we will be able to meet increased demand for many years to come.”
“We have produced Kanthal wire in Hallstahammar since 1931, except for the past five years,” said Nicklas Nilsson, president at Kanthal. “It’s great to close the circle and once again see the drawing mill up and running.”
A North American extrusion and forging grade billet producer recently announced plans to proceed with new aluminum remelt facilities for billet and slab ingot casting and related processes and services. This will involve new facilities, increasing the company’s existing 1 billion pounds per year capacity by 75%.
With this approval from the Giampaolo Group Management Board, Matalco increases capacity by 350 million pounds in Lordstown, Ohio, 180 million pounds in Canton, Ohio, 225
million pounds in Bluffton, Indiana (previously Alexin LLC), and 250 million pounds in Brampton, Ontario.

Earlier in the year, Matalco acquired Alexin LLC.
The catalyst for these investments is in response to the needs voiced by customers in under-served market geographies, their requirements for increased product breadth, and processing services for the vast and growing automotive fflat-rolled aluminum product supply chain and the product feature needs of specialty alloy aluminum billet markets.
“We are an established leader in the remelt aluminum business. Matalco’s four existing aluminum plants have the broadest product offering and flexibility for providing closed loop, scrap-based billet, and slab ingot products,” said Tom Horter, president of Matalco USA Operations noted. “The proven capabilities of our people, assets, and technologies provide the nucleus and granularity for understanding market challenges and generating the solutions to meet the
future supply chain requirements of our customers.”
Horter added, “The recent integration of Alexin into Matalco has provided the right base for new employee training and innovative product and process development enabling speed to
market in these growing niche areas, bringing to life the exciting business possibilities to attain the Giampaolo Group’s medium and long-term objectives for our businesses.”
Matalco has not announced the number of plants that have been approved, nor their exact locations.
“Our team has been working with state and local economic representatives in the Upper Midwest states of Michigan, Illinois, Wisconsin, and Minnesota, and the southern states of Alabama, Tennessee, and Kentucky,” said Frank Mastrandrea, from the Giampaolo Group Management Board.
Induction heat treaters know that proper coil design is crucial to increasing longevity, improving production quality, and cutting costs. The authors of this paper on Coil Design Techniques (C. Yakey, V. Nemkov, R. Goldstein, J. Jackowski) draw on an extensive library of published case histories in induction coil design and performance evaluations and provide their own case study of an automotive CVJ stem hardening coil in order to demonstrate how the elimination of failure points and application of improved design guidelines can result in increased coil lifetimes, even in an inductor that in some circumstances can have a short lifetime.
An excerpt:
“The quality of an induction coil is a major determinant of the cost to produce induction heat treated components. Oftentimes, the difference between a well designed and manufactured inductor and a poor performing inductor is not readily apparent. However, a high-quality induction coil can lead to substantially lower component manufacturing costs and higher profitability for the induction heat treater.”

A Texas-based manufacturer of custom-built, match-grade rifles and performance parts for rifles and pistols recently announced that superior vacuum heat treatment capabilities result in the expansion of its line of parts for Steyr Arms Inc. A-1 pistols.
Ranger Point Precision, based near Houston, Texas, reported that their advanced heat treating process and salt bath black nitride allows for the conversion of any 40 S&W pistols to a .357 Sig, delivering match-grade accuracy, increased durability, reduced chamber friction, and extended barrel life. The expanded line includes both standard and threaded options along with thread protectors and mini-comps for .357 Sig / 9mm calibers.
“We start with premium Douglas barrel blanks with precise rifling, then use minimum spec chamber reamers, and the most advanced methods for heat treating and salt bath black nitride to produce the best Steyr pistol barrel available on the market,” said Adam Devine, CEO, co-founder, and head of R&D, Ranger Point Precision.
Steyr .357 pistol barrels are vacuum heat treated to 42 HRC and salt bath black nitride coated, giving them a surface hardness above 80 HRC.
The Industrial Heating Equipment Association’s monthly economic executive summary reported very strong gains for both automotive and light truck sales as well as new home starts. Regarding new home starts, here is an extended quote for the 12-page monthly report available in full to IHEA members:
The news in the housing sector is very good right now and that is in the face of those headwinds that have been referenced all year. Thus far the consumer is shrugging out the higher price of homes as well as the bigger down payments and there has been buying at a variety of levels – from the starter home to the much more expensive “McMansion.” The fastest growing segment is still the multi-family home and there are still major shortages of this kind of abode. The recovery this month after a down period the month before is somewhat related to the weather, but not as much as would have been assumed this time of year. There is evidence that housing activity is surging in the jobs data as well – over 60,000 jobs added in construction this month. The majority of these are in the housing sector as there has not been a huge recovery in either commercial construction or in public sector activity.
The dozen indicators reported were split evenly between those that were up and those that were down. Significant is the fact that the PMI saw a slight dip but has been strong, in the mid-sixties, for quite some time, reaching a peak in December 2017 at 70.
