Abstract
High temperature gas nitriding (HTGN) for austenitic stainless steel 316LVM is successfully done. Specimens are treated at temperature 1323, 1373 and 1573 K for 15 minutes holding time at 0.3 atm nitrogen gas pressures. As received and treated specimens were evaluated by means vickers micro hardness test, metallographic examination, abrasive wear test, corrosion test and vibrating sample magnetometer test. Hardness, wear resistance and grain size increase with temperature. However, the corrosion resistance at ringer solution decreases with temperature. HTGN treatments at 1323 K for 15 minute holding time are able to improve the hardness, wear resistance, corrosion resistance and increase the non-magnetic stability of 316LVM.
