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