A C+N austenitic stainless steel includes 15 to 20% by weight of chromium (Cr), 8 to 12% by weight of manganese (Mn), 3% or less by weight of nickel (Ni), and 0.5 to 1.0% by weight of a total content (C+N) of carbon (C) and nitrogen (N), remainder iron (Fe), and other inevitable impurities. A ratio (C/N) of the carbon (C) to the nitrogen (N) ranges from 0.5 to 1.5. It is possible to provide austenitic stainless steel having excellent low-temperature toughness while satisfying the requirements of strength, ductility, and pitting corrosion resistance and minimizing the nickel content |
