This heat-resistant austenitic stainless steel sheet contains, in mass %, C: 0.05 to 0.15%, Si: 1.0 to 3.5%, Mn: 0.5 to 2.0%, P: not more than 0.04%, S: not more than 0.01%, Cr: 23.0 to 26.0%, Ni: 10.0 to 15.0%, Mo: 0.50 to 1.20%, Ti: not more than 0.1%, Al: 0.01 to 0.10% and N: 0.10 to 0.30%, wherein the total amount of C and N (C+N) is from 0.25 to 0.35%, and the balance is composed of Fe and unavoidable impurities. The heat-resistant austenitic stainless steel can be used in a high-temperature environment that reaches a maximum temperature of 1,100°C. |
