摘要
A high-Ni austenitic stainless steel having swelling resistance, high- temperature creep strength, and phase stability under irradiation. The irradiation resistance and high-temperature strength of the high-Ni austenitic stainless steel are enhanced when it is composed of the following percentages by weight: Si, not exceeding 0.5 wt. %; Mn, not exceeding 1.0 wt. %; Cr, 13-18 wt. %; Ni, 30-50 wt. %; Mo+W=2.0-6.0 wt. %; Nb+V=0.1-0.8 wt. % (Nb/(Nb+V) [weight ratio]=0.20-0.85 [weight ratio]; N, 0.01-0.2 wt. %; and the residual consisting of Fe and unavoidable impurities.
