Abstract

PURPOSE:To obtain the titled stainless steel having high corrosion resistance and hot workability at a low cost by specifying the compsn. contg. C, Si, Mn, Cr, Mo, Ni, N, Al, P and S and the compositional relationship thereamong. CONSTITUTION:The titled stainless steel contains, by weight, 0.0005-0.050% C, 0.02-1.0% Si, 0.05-2.0% Mn, 21.0-27.0% Cr, 4.0-6.0% Mo, 19.5-23.2% Ni, 0.15-0.22% N, 0.005-0.30% Al, 0.0005-0.050% P and 0.0005-0.010% S, furthermore contains at need, one more more kinds among <=2.0% Cu, <=0.5% W, <=1.0% Ti, <=1.0% Nb, <=1.0% V, <=1.0% Zr, <=0.02% La, <=0.02% Ce and <=0.02% Ca and satisfies the formula of 40.8<=Cr+3Mo13N and 1/2(Cr+ Mo)+7.7<=Ni+10N<=1/2(Cr+Mo)+10.7. Said steel has high corrosion resistance and excellent hot workability.
