ADHESIVE WEAR CHARACTERISTICS OF CAST NITROGENATED STAINLESS-STEEL

Adhesive wear characteristics of nitrogenated Fe-Cr-Ni and Fe-Cr-Ni-Mn type cast austenitic stainless steels have been investigated Stainles s steels in which nickel is partially substituted by manganese and nit rogen demonstrate better wear resistance and lower friction coefficien t particularly when the titanium content is also raised simultaneously . The wear surface undergoes heavy work hardening which retards furthe r wear, In contrast, molybdenum does not contribute to improved wear r esistance in cast austenitic stainless steels.
