Solution nitriding is a controlled heat treatment of stainless steels carried out at 1100 ± 50 °C in N 2 gas. Depending on the alloy content a hard martensitic or a ductile austenitic high nitrogen case of about 2 mm in depth is formed, which reduces wear by sliding, fretting, erosion and cavitation. In contrast to carbon dissolved nitrogen does not impair the resistance to superimposed corrosion, so that solution nitriding is suitable for components subjected to the flow of aggressive fluids containing suspended particles which is often encountered in chemical and process engineering.
