[Problem] To reduce anisotropy in workability and fatigue resistance caused by oxide inclusion in austenitic stainless steel. [Solution] An austenitic stainless steel sheet wherein: the stainless steel sheet is formed from, in percent by mass, 0.030 - 0.300% C, 0.30 - 3.20% Si, 0.90 - 17.00% Mn, 1.00 - 8.00% Ni, 14.00 - 19.00% Cr, 0.50 - 3.50% Cu, 0.045 - 0.250% N, 0.0001 - 0.0300% Al, 0 - 0.50% V, 0 - 0.50% Nb, 0 - 0.30% Ti, 0 - 0.010% B, with the remainder being Fe and inevitable impurities; and converted average composition for oxide inclusion is 30% by mass or less Al2O3, 60% by mass or less SiO2, and 15% by mass or greater MnO, and MnO ≥ -3SiO2 + 110 is satisfied. |
