In this research work, the vacuum annealed stainless steel samples were subjected to a constant load. The wear behavior of AISI 431 sample were examined by using pin on disc wear tester. The vacuum annealing were used to preserve the stability between ductility and brittleness. The samples were created in cylindrical shape with a length of 40 mm and diameter 8mm. For this current research, 3 samples are treated at 600°C, 660°C, 820°C temperatures and they were assigned asA1, A2 and A3 respectively. The outcome of vacuum annealing is that to reduce the hardness and increase in ductility, to overcome the material from defects and release internal stress. The hardness, wear behavior were measured for the treated and untreated samples. To evaluate the wear behavior, comparison of results, wear test studies and scanning electronic microscope analysis were done.
