摘要： Austenitic stainless steel includes 16 to 26 wt % of chromium (Cr), 8 to 22 wt % of nickel (Ni), 0.02 to 0.1 wt % of carbon (C), 0.2 to 1 wt % of niobium (Nb), and 2 to 3.5 wt % of manganese (Mn), and has an austenite matrix, wherein a nanosized niobium carbide (NbC) is precipitated in the austenite matrix, and the nanosized niobium carbide is uniformly dispersed in the austenite matrix. The austenitic stainless steel may further include 0.5 to 1.5 wt % of molybdenum (Mo).
