Abstract

PURPOSE: To manufacture a high-tensile steel wire excellent in ductility by providing the surface of a steel wire, which has a specific composition and in which the difference of hardness between the center and surface is controlled to a specific value or below, with residual compressive stress according to the strength of the steel wire.
CONSTITUTION: The steel wire has a basic composition consisting of, by weight, 0.4W1.0% C, <2.0% Si, 0.2W2% Mn, <0.02% P, <0.02% S, <0.01% N and the balance Fe or further contains 1 or ≥2 kinds among 0.05W3% Cr, 0.01W1% Mo, 0.01W1% W, 0.05W3% Cu, 0.1W5% Ni and 0.1W5% Co or 1 or ≥2 kinds among 0.001W0.1% Al, Ti, Nb, V and Mg and 0.0003W0.05% B independently or in combination. Furthermore, the difference of hardness between the center and surface of the steel wire is limited to ≤100 vickers hardness and the surface is provided with a residual compressive stress of (0.05σ+13)W(0.35σ+28)kgf/mm2 according to the strength (σ) of the steel wire, so that high-tensile steel wire excellent in ductility can be obtained.
