Abstract By using SEM,optical microscope and Gleeble 3800,the microstructure and mechanical properties of TGOG13Cr1 super martensitic stainless steel were studied. The result showed,that the microstructure of TGOG13Cr1 at room temperature is lowcarbon tempering martensite,with Ac1 720 ℃,Ac3 860 ℃, Ms 281 ℃ and Mf 157 ℃;For same quenching temperature and tempering process, the mechanical properties are easier to control by water quenching than by air quenching; the higher the tempering temperature, the lower the strength and hardness, and the better the plasticity and toughness are.
