HIGH TENSILE STRENGTH STEEL WIRE ROD AND FINE DIAMETER HIGH TENSILE STRENGTH STEEL WIRE

摘要

PROBLEM TO BE SOLVED: To provide a high tensile strength steel wire rod excellent in wire drawability and to provide a fine diameter high tensile strength steel wire produced by using the steel wire rod and excellent in ductility. ;SOLUTION: This high tensile strength steel wire rod excellent in wire drawability has a compsn. contg., by weight, 0.90 to 1.10% C, ≤0.4% Si, ≤0.5% Mn, ≤0.020% P, ≤0.020% S and 0.10 to 0.80% Cu, moreover contg., at need, one or two kinds of 0.10 to 0.30% Cr and 0.10 to 1.00% Ni, and the balance iron with inevitable impurities, in which the content of inevitably contained Al is also controlled to ≤0.003%.;COPYRIGHT: (C)2000,JPO
