Abstract
PURPOSE:To obtain a sheet metal of two-phase stainless steel excellent in pitting corrosion resistance in a weld zone, by specifying a composition consisting of C, Si, Mn, Cr, Ni, Mo, N, P, S, and Fe and forming a directly cast sheet metal material. CONSTITUTION:A two-phase stainless steel having a composition which consists of, by weight, <=0.1% C, <=2% Si, <=2% Mn, 20-30% Cr, 3-15% Ni, 0.5-5% Mo, 0.15-0.35% N, <=0.04% P, <=0.04% S, and the balance Fe with inevitable impurities and further contains, if necessary, <=2% Cu and satisfies the inequality (120N+2Ni)-(Cr+Mo+4.4)>=0, composed of directly cast sheet metal material, and excellent in corrosion resistance in a weld zone as well as in the corrosion resistance of the material itself is prepared. The above-mentioned directly cast sheet metal material can be manufactured by treating a molten steel of the above composition by a rapid solidification process of double belt type, drum type, etc.
