AN INVESTIGATION OF MECHANICAL PROPERTIES ON NITRIDED AUSTENITIC STAINLESS STEEL

Austenitic Stainless Steel (ASS) has been used widely in industry because of its excellent corrosion properties. However, due to its inherent austenitic structure, it exhibits slightly low hardness and wear resistance. Thus, it limits its application. In this study, the ASS are treated with gas nitr...
