Note: Nitrogen stainless steel alloys are susceptible to denitrization. They must be protected during heat treatment or the nitrogen will be burned off similar to carbon and decarburization. I spoke to a metallurgist about denitrization. She recommended the following options: - A foil bag inside a vacuum furnace. - A heat treat furnace filled with nitrogen during heat treating. - A sealed foil bag inside another sealed foil bag during austenitizing.
Preheat: Put in a preheated furnace at 1,110-1,200°F. Equalize temperature. Increase to 1,550-1,650°F. Equalize temperature.
Austenitize: Heat to 1,800-1,900°F and soak for a maximum of for 40 minutes.
Quench: Plate, air or medium oil quench. Cool to 100°F before tempering.
Cryo: It is recommended to perform subzero or cryo to -185°F for 30 minutes before tempering.
