Abstract
This study deals with the characteristics of degraded stainless steel. Stainless steel is heat treated to ensure mechanical properties when designing or manufacturing machinery parts or equipment. In this study, the mechanical properties and wear characteristics of three kinds of stainless steels after artificially heat-treated at 753 K~993 K, where chrome depletion occurs near the grain boundary, were evaluated. The microstructure and fracture surface were also observed. From the results, friction coefficient and wear loss decreased with increasing the heat treatment temperature regardless of the type of stainless steel. Also, as the tensile strength increased, the friction coefficient and wear loss decreased. Wear loss showed proportional to a tendency to increase with increasing friction coefficient.
