The tribological properties of 304 austenitic stainless steel were studied.304 balls,316 balls,GCr15 balls,ceramic balls were used for the treatment of 304 austenitic stainless steels respectively,using a universal friction tester at different temperatures.And the friction surface of the disk was observed by using the threedimensional morphology method.Finally,the friction performance of the disk was studied by using high temperature friction and wear tester.The results show that the wear resistance of 304 stainless steel is weaker than that of 316 steel,GCr15 and ceramic just under dry friction condition;with the increase of temperature,the internal structure of 304 stainless steel becomes soft and the friction coefficient decreases gradually;at the same time,the adhesion between the samples is gradually increasing with increasing temperature,which also conforms to the trend of friction coefficient.
