SECO/WARWICK Corp. sold a 15-bar high-pressure gas-quench furnace to a U.S. commercial heat treater. Scheduled for shipment to the company’s facility in the southeast in spring 2015, the unit will be used for through-hardening of molds, dies and various tool steels. The furnace is equipped with PreNit® LPC (high-speed carburizing), pre-nitriding and LPC vacuum carburizing. PreNit is a patented pre-nitriding option for low-pressure vacuum carburizing. It broadens the applications for LPC vacuum carburizing by utilizing higher temperatures.
