Heat treatment is a combination of heating and cooling operations to a metal or alloy in the solid state in a way that will produce desired properties. Due to improper material and surface hardening treatments, the quality of tools does not conform to the Bureau of Indian Standards resulting in high wear rates and reduced life. The experiments were conducted on pin-on disc wear machine with three heat treatments, hardening and tempering, chromium nitride coating and Cryogenic treatment were selected. Minimum wear loss of 0.0064 g was observed in T2 followed by 0.0071 T3, 0.0113 T1and 0.0684 g T4 treatments. The wear loss of materials with harden and tempered, coated and cryogenic treatments were found 35.49, 66.42 and 53.52 per cent less than that of the untreated material.
