Abstract

PURPOSE:To improve corrosion resistance together with both characteristics of machinability and cold forgeability by lowering the content of C in a free- cutting stainless steel and incorporating Pb, Te, Se, Bi, etc., at specific ratios into said steel. CONSTITUTION:The compsn. of a martensitic free-cutting stainless steel is constituted by incorporating, by weight %, <=0.07% C, <=0.40% Si, 0.10-1.0% Mn, 10.0-13.0% Cr, and <=0.02% N, and >=1 kinds among 0.03-0.30% Pb, 0.01-0.15% Te, 0.01-0.15% Se and 0.01-0.15% Bi into the compsn. and consisting the balance of Fe and impurity elements. In addition, the Cr equiv. is specified to a 9.0-10.5 range. Further, >=1 kinds among <=0.50% Cu, <=1.5% Mo, <=0.2% Ti, <=0.15% V, and <=0.10% Nb are incorporated therein. This steel has the excellent cold forgeability in an annealed state and has the excellent machinability and corrosion resistance.
