Nitriding Steels

Nitriding results in greater wear resistance and anti-galling properties.Nitriding is a heat-treatment process which results in a case-hardened surface.


Nitrided steel is often referred to as case hardened steel and is typically performed on low-alloy products. The method uses nitrogen, which is introduced into the surface of the material, increasing the surface hardness of the product.

The result is steel which offers good wear resistance and anti-galling properties.
