Gas Nitriding

Gas nitriding is a case-hardening process whereby nitrogen is introduced into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia The nitriding temperature for all steels is between 495 and 565°C (925 and 1050°F) Principal reasons for nitriding are:...
