Gas Nitriding

img-37Nitriding is a case hardening process which consists of the introduction of nitrogen, usually as ammonia gas, to machined and heat treated ferrous alloys to harden the surface layer without requiring any further quenching treatment.

Processing temperatures are commonly 975-degrees-F to 1050F (525 to 565-c). Nitriding produces a hard, wear resistant surface, and results in properties that are resistant to corrosion and surface stresses that cause premature.
