PURPOSE:To improve the long-time elongation at creep repture by adding pre scribed percentages of C, Si, Mn, P, Ni, Cr and Mo to Fe. CONSTITUTION:The titled stainless steel consists of, by weight, <=0.015% C, <=3% Si, <=3% Mn, 0.045-0.2% P, 7-22% Ni, 14-25% Cr and the balance Fe or further contains <=3% Mo. The steel ahs superior long-time elongation at creep rupture and is used as a heat resistant structural material in a creep region.
