Microstructure and mechanical properties of low?temperature gas carburized layer of AISI316 austenitic stainless steel were investigated by means of scanning electron microscopy(SEM),micro hardness tester,CS electrochemical workstation. The experimental results indicate that the thickness of hardened layer is within the range of 10 to 33 μm,when AISI316 austenitic stainless steel is carburized at 450,470,500 ℃. With the variation of carburizing temperature,different case depth,hardness gradient and corrosion resistance are observed in the steel.
