Abstract

High-temperature oxidation tests of 3Cr13 steel were performed at 500,650,800 and 950 ℃,respectively.The morphology,composition and phase structure of oxidized surfaces were analyzed using SEM and XRD to discuss the high temperature oxidation resistance of 3Cr13 steel.The results show that the specimen surface is not completely covered by surface oxide which remains almost zero at 500℃.There is a protective layer on specimen surface which lowers the speed of oxidation over 570 ℃.The surface oxide increased rapidly and the oxidation reacts violently when oxidized longer at 950 ℃.
