SECO/WARWICK Corp. commissioned a new, advanced furnace design that provides improved durability for stainless steel heat treating. The vacuum furnace, which is equipped with a 15-bar gas-quenching system and a full HMI data-retrieval control package, was built for a northeast U.S.-based manufacturer of stainless steel products. The SuperExpanite process improves the hardness and corrosion resistance for stainless steel. It is a new treatment process, not a coating.
