Industrial Heating, in cooperation with the Metal Treating Institute and the MTI Educational Foundation, invite you to nominate an MTI member company for the 2019 Commercial Heat Treater of the Year award. You can nominate any company you feel is qualified – including your own if you are a commercial heat treater. This honor will be given to one MTI commercial heat treater that demonstrates they are “making a positive impact on their community and their industry.”
Solar Atmospheres of Western PA installed a 14-foot-long car-bottom air furnace that was surveyed in accordance with AMS2750 Rev E and is uniform within ±10°F (Class 2). With a work zone measuring 60 inches wide x 54 inches high x 168 inches long, the furnace will be capable of handling workloads up to 30,000 pounds. A maximum operating temperature of 1400°F allows the furnace to accommodate the tempering of large tool-steel components and the age-hardening processes of nickel-based alloys and precipitation-hardenable stainless steels.
JGEF Furnace installed a series of nitrocarburizing furnaces at a commercial heat-treatment company’s recently opened 53,820-square-foot facility in Chongqing, China. The furnaces are designed to maintain temperature uniformity of ±3°C. The series of pit nitrocarburizing furnaces use software that controls the nitriding potential and maximizes the efficiency of the process. The systems are capable of maintaining the preset values of Kn, and the process requires no manual adjustments from start to finish.
Allegheny Technologies Inc. (ATI) agreed to sell two non-core forging facilities to Wynnchurch Capital for $37 million. These facilities, located in Portland, Ind., and Lebanon, Ky., are part of ATI’s High Performance Materials & Components (HPMC) segment. They use primarily traditional forging methods to produce carbon-steel forged products for use in the oil and gas, transportation, construction and mining industries. Their capabilities include comprehensive forging processes complemented by in-house design and engineering, product machining and heat-treating services.
The Timken Company acquired Diamond Chain Company, a supplier of high-performance roller chains for industrial markets, from Amsted Industries. Indianapolis, Ind.-based Diamond Chain has manufacturing operations in the U.S. and China and employs approximately 370 people. The company uses enhanced heat-treatment processes that help pins maintain rigidity in the most challenging environments. Diamond Chain also utilizes laser fabrication to drastically cut manufacturing times for custom-made chain attachments.
Epiroc, a productivity provider for the mining and infrastructure industries, held a groundbreaking ceremony for a new heat-treatment plant for rock drills in Örebro, Sweden. The 1,400-square-meter facility, which will be able to run 24 hours a day due to automation, is expected to be up and running by late 2020. The plant was designed for energy efficiency. For example, residual heat will be recycled internally to heat buildings.
The application of ion/plasma nitriding to powder-metal (PM) products is recommended over the gas nitriding method. Ion/plasma nitriding results in surface hardening while gas nitriding causes unintended through-nitriding, making the treatment not suitable for a majority of engineering components made of PM.
Family-owned heat-treatment company GalvanoTechnik of Lombardy, Italy, expanded its portfolio to include Nitreg-controlled nitriding, Nitreg-C nitrocarburizing and ONC in-process oxidation treatments. The company invested in a compact Nitrex system configured to process 23.5-inch-diameter x 35.5-inch-high workloads that weigh up to 1,300 pounds. The system complies with the temperature-uniformity requirements of AMS 2750E and meets the specifications of ASM 2759/10, which make it possible to consistently achieve the required metallurgical and mechanical properties for controlled nitriding.
SECO/WARWICK Group’s subsidiary based in Meadville, Pa., has been awarded a major contract to build and commission a specialized aluminum solution heat-treating furnace for a U.S. manufacturer. The furnace, which is AMS 2750-compliant and Nadcap-capable, will be engineered to load, heat treat, quench and discharge with minimal operator assistance. It will be used to heat treat products for automotive, aerospace and medical applications.
