Vacuum Nitriding,Vacuum Nitriding steel,Vacuum Nitriding-Vacuum Nitriding steelVacuum Nitriding. Vacuum furnaces, especially vacuum tempering furnaces, can be used for nitriding of tools. The
tempering furnace is ideally suited for this purpose because it is designed to operate in the nitriding temperature range.
For high-speed steels and other tools tempered at 455 to 595 °C (850 to 1100 °F), the nitriding cycle can be incorporated
into the final tempering cycle, by introducing a partial pressure of ammonia during the final temper. In this way, the
vacuum furnace operates similar to a normal nitriding furnace, except that nitrogen or the vacuum itself acts as the
dilutant for nitriding, replacing dissociated ammonia. Cycle times would be the same as for gas nitriding.
