WebNitriding is the diffusion of nitrogen into the surface of special alloy steel to give a hard surface and soft core without the need for further treatment. Processing is generally carried out in the temperature range 470ºC to 530ºC in an atmosphere of ammonia, although other processing media can be used, such as salt baths and plasma. Nitriding is only carried … Webnitriding, process for hardening the surface of steel objects by introducing nitrogen (N) into it, where it combines with iron and other alloying elements to form hard metallic nitrides.
