The as-quenched properties of powder metallurgy steels depend on the cooling medium and the steel’s hardenability. Quenching in water, salt, brine, and water-based polymer solutions improves the rate of heat transfer, leading to a faster quench. However, in many cases, it accelerates corrosion due to the residual quenchant trapped in surface pores.
Lucifer Furnaces, Warrington, Pa., has designed a multi-unit modular pot furnace system for a major aerospace manufacturer in the U.S., who will use these furnaces to increase heat treat capacity.
Steel Dynamics, Fort Wayne, Ind., has been named one of the 100 Best ESG Companies of 2021 by Investor’s Business Daily. Steel Dynamics was the only U.S. steel producer receiving this designation, and one of only three steel producers globally.
Harper International, Buffalo, N.Y., has launched a lab-scale rotary furnace. The furnace allows producers of advanced materials to optimize their process parameters on a small scale to ensure capability and quality requirements are achieved prior to investment in production-scale thermal process equipment.
Ipsen, Cherry Valley, Ill., has presented donations to support the MTI Educational Foundation, which provides scholarships for the next generation of heat treating industry professionals during the Metal Treating Institute’s Fall Meeting, along with several other vested organizations.
