A method of manufacturing austenitic stainless steel with low nickel having superior hot workability is provided to restrict the content of Ni within 5 weight percent by adding Cu and Mn. A method of manufacturing austenitic stainless steel comprises a step of adjusting the content of Mn and Cu such that hot workability obtained by the following equation is set to 60 or above. Hot workability = -63.61-4.77 X Cu + 40.35 X Mn - 3.08 X Mn X Mn. The austenitic stainless steel includes 0.10 weight percent or less of C, 0.30 weight percent or less of N, 3.0 to 5.0 weight percent or less of Ni, 4 to 10 weight percent or less of Mn, 14.0 to 18.0 weight percent of Cr, 1.0 to 3.0 weight percent of Cu, Fe, and inevitable impurities. |
