摘要

PROBLEM TO BE SOLVED: To produce a steel excellent in cold workability and induction hardenability, and in which grains are not coarsened by induction hardening, to produce parts for machine structures using it as a base material steel and to provide a method for producing the same. ;SOLUTION: A steel for cold working excellent in induction hardenability is the one having a compsn. contg., by weight, 0.40 to 0.60% C, 0 to 0.40% Si, 0.10 to 0.60% Mn, 0.0005 to 0.005% B, 0.005 to 0.05% Nb and 0.015 to 0.10% Al, furthermore contg. 0 to 0.30% Pb, 0 to 0.10% Bi and 0 to 0.10% Te, and the balance Fe with inevitable impurities, and in which, in the impurities, ≤0.015% P, ≤0.015% S, ≤0.10% Cu, ≤0.10% Ni, ≤0.15% Cr, ≤0.10% Mo, ≤0.005% N and ≤0.005% O are regulated. Parts for machine structures are ones in which a base material steel has the similar chemical compsn., having spheroidized carbides and provided with a quench-hardened layer on the outer circumferential part.;COPYRIGHT: (C)1999,JPO
