After the fill/purge cycle, ammonia is introduced and heated to begin the nitriding process. The gas nitriding process consists of heating the components in a furnace with a retort in which air has been replaced with ammonia gas. Inquire Now. The original Gas Nitride process is a “low temperature” furnace treatment with an atmosphere of Ammonia. A Nitrex furnace consumes a very similar amount of gas to what an ion one does for a comparable batch. As an alternative furnace style for ferritic nitrocarburizing, a lift cover, carbottom, or  Allcase® furnace can perform to the same exacting specifications. It can be customized to production requirements. Industrial Aluminum Dies Vacuum Gas Nitriding Furnace Price.
