摘要

Disclosed is a carbonaceous austenitic stainless steel having excellent mechanical properties and corrosion resistance. Austenitic stainless steel according to an embodiment of the present invention in weight%, chromium (Cr): 17.5 ~ 18.5%, manganese (Mn): 9.5 ~ 10.5%, carbon (C): 0.18 ~ 0.22%, nitrogen (N ): 0.26 ~ 0.32%, tantalum (Ta): 0.25 ~ 0.35%, characterized in that consisting of the remaining Fe and inevitable impurities. Austenitic stainless steel according to another embodiment of the present invention by weight%, chromium (Cr): 17.5 ~ 18.5%, manganese (Mn): 9.5 ~ 10.5%, carbon (C): 0.18 ~ 0.22%, nitrogen (N ): 0.26 to 0.32%, tantalum (Ta): 0.05 to 0.16%, niobium (Nb): 0.08 to 0.19%, characterized in that consisting of the remaining Fe and inevitable impurities.
