Ipsen ships Turbo Treater vacuum furnace to commercial heat treater in Mexico

Ipsen, Tainan City, Taiwan, has shipped a vacuum furnace to Tratamientos Termicos Avanzados (TTA) in Mexico. Translated to “Advanced Heat Treatments,” TTA is a leader in plasma nitriding services for steel. They serve many industries and boast a clientele that includes John Deere, Caterpillar and Nissan.

Looking to expand their capabilities by adding vacuum processing to their commercial heat-treating business, they chose an Ipsen Turbo2Treater for its process flexibility. The new furnace has a work zone size of 24” x 24” x 36”, 1,600 lb. weight capacity, 2,400 °F maximum operating temperature, and quench pressure up to 12 bar. It will mainly be used for hardening tool steels but can easily be adapted to meet new customers’ needs.

TTA chose Ipsen for their ability to lead them in the right direction to grow their business.

Nitrex and Linde renew their 13-year collaboration

Nitrex, Quebec, and Linde are celebrating their 13-year collaboration, which today covers Europe and North America. Nitrex said that this partnership emphasizes both companies’ positioning in terms of technology, digital, and green footprints. 

The cooperation between Linde (previously Praxair) and UPC-Marathon, a Nitrex company, began in the USA in 2010, when Linde approached UPC-Marathon to build gas panels. Eventually, the company started sending some of its clients who needed technical support in UPC’s direction.

Nitrex supplies Linde with equipment and analyses to control gas atmospheres, thanks to its competence in heat treatment and electrical fields, technical solutions, support, and world-class gas panels.

Solar Atmospheres of Michigan’s relocation charges forward

Solar Atmospheres, Chesterfield, MI, formerly known as Vac-Met Inc., has successfully reached its first milestone in the relocation phase. Solar invested over $5 million of new equipment installed with all new utilities. 

The new equipment includes two vacuum furnaces, an air tempering furnace, and a freezer. As a result, Solar was able to host their first AS9100D audit at the new facility in Chesterfield Michigan. This quality management system audit for aviation, space and defense organizations which incorporates ISO9001 standards passed with zero findings.After purchasing the company one year ago, the goal was to build a new facility with no impact on the existing customer base.

One Minute Mentor: Controlled Atmosphere Furnace Equipment

Heat treatment of tool steels usually requires high flexibility combined with small lots of parts. Seal quench furnaces, executed with a single heating chamber, meet this demand. Figure 5 shows a typical schematic of a single-chamber furnace, executed with a pre-chamber, which is used both for loading and unloading and also for oil quenching or gas cooling. Another execution is shown in Fig. 6, where the load is fed directly into the heating chamber (left side in the drawing). In this case the load is transported through the furnace and received after oil quenching on the right-hand side.

Rolled Alloys celebrates 70 years in the thermal processing industry

Rolled Alloys, Windsor, Conn., is celebrating 70 years in the thermal processing industry. 

The company was founded in 1953 by introducing RA330 as a wrought replacement to cast HT.

Due to RA330’s versatility and availability, it remains the most widely used wrought alloy by commercial heat treaters. Although RA330 exhibits excellent features, there may be better choices for an application. With this being the case, we offer a wide range of heat-resistant alloys to best suit the needs of your application.

Besides this, RA 602 CA is an alloy developed specifically for the highest temperature process, requiring strength and resistance to atmospheres. 

One last alloy worth discussing is RA253MA. RA253MA is a lean, heat-resistant stainless steel with high strength and oxidation resistance. With excellent high-temperature properties and low nickel content, RA253MA is a cost-effective material that thermal processors frequently utilize for open-air applications.

Steel Dynamics named one of America’s best employers for women by Forbes

Steel Dynamics, Fort Wayne, Ind., has been named one of America’s Best Employers for Women for 2023 by Forbes. Steel Dynamics was the only steel producer receiving this designation.

“We are appreciative and honored by this recognition,” said Mark D. Millett, chairman and chief executive officer. “Our people are the foundation of our success and our most important resource. We strive to create a welcoming, open, and inclusive environment. We value our team members, creating meaningful opportunities for growth, leadership development, and career advancement. We believe empowering our people and providing them with the necessary tools for success creates significant value for everyone and will drive our continued success.”

Forbes partnered with Statista to compile the list of America’s Best Employers for Women. Statista surveyed over 60,000 U.S. employees working for companies with a minimum of 1,000 employees. More than 40,000 women were asked to rate their company in areas such as working environment, salary and employee diversity, and then whether they would recommend their company to a friend or family member.

One Minute Mentor: Plasma Nitriding Equipment

One Minute Mentor: Plasma Nitriding Equipment

Cold-walled (double-walled water-cooled) systems were the first generation of plasma nitriding furnaces. This technology is also a vacuum-based process but employs the principle of glow discharge to provide energy for heating and nitriding at one time. Therefore, the independent control of the temperature stability and the nitriding intensity is not possible because both processes are using the same energy source—the plasma.

The hot-wall plasma nitriding furnaces, the next generation of cold-wall ion nitriding systems, are mainly used and built now. This system ensures optimal nitriding quality by fulfilling the highest demands on temperature and nitriding process control. The big advantage of this technology is the separation of the control of the heating and the plasma nitriding parameters.

Evolution on the microstructure and mechanical properties of a new multicomponent near-Alpha Titanium Alloy after rolling and heat treatments

Beijing University of Technology, China, presented the microstructure and mechanical properties of a new type of multi-component near-α titanium alloy sheet after rolling, 700°C aging, and 800°C aging in a new paper.

 The results show that the strength of the alloy after aging at 700°C increases from 1156 MPa to 1304 MPa, respectively, but decreases to 1246 MPa with the aging temperature increasing. The ductility of the alloy aged at 700°C is lower than that of the rolled state, but the ductility increases slightly with the aging temperature increasing. The effect of aging heat treatment on the microstructure and precipitation behavior of alloy plates has been studied and compared with alloys before aging. 

After heat treatment, the content of primary α decreases from 25% to 5%, respectively. Two kinds of silicide precipitate at different positions, with the large-size spherical silicide being (Ti, Zr, Nb)5Si3, and the small-size fusiform silicide being (Ti, Zr, Nb)6Si3, respectively. Ti3Al was precipitated in the primary α phase, during the aging process. The silicides exhibit the strengthening effect on the alloy, but the effect weakens when the silicides grow up. The loss in ductility is mainly attributed to the precipitation of the α2 phase after aging treatment. However, ductility is improved after applying higher aging temperatures as the size of the α2 phase becomes smaller, and the distribution of them tends to become dispersed.
