Title:

WIRE ROD FOR HYPERFINE WIRE HAVING SUPERIOR WORKABILITY

Document Type and Number:

Japanese Patent JPS60152659

Kind Code:

A

Abstract:

PURPOSE: To obtain a wire rod for a hyperfine wire having superior workability by adding specified percentages of C, Si and Mn to Fe and reducing the amounts of P, S, Cu, Ni, Cr, O and N contained to a specified value each.

CONSTITUTION: A wire rod consisting of, by weight, 0.60W0.90% C, 0.10W0.50% Si, 0.30W1.00% Mn, <0.010% P, <0.005% S, <0.10% in total of Cu, Ni and Cr, ≤30ppm total oxygen, ≤30ppm total nitrogen and the balance Fe is manufactured. When the wire rod is used, a wire of ≤about 0.4mm suitable for use as a material for a tire cord or a belt cord is obtd.
