Material Selection

Material Selection

Material selection affects surface hardness and depth of hardness. Typically the surface hardness of low to medium carbon steels and certain alloys ranges from 550-700 HV with depths of .0002" to .0008" depending on the cycle time. The surface hardness of stainless steels generally is 840 HV or greater at a depth of .0002" to .0015". Depending on material type, the continuation of nitrogen penetration in the diffusion zone occurs to a depth of between .003" to .040" at a descending gradient of hardness.

Materials Commonly Salt Bath Nitrided
