The wire rod null for the melting plated steel wire which is superior in resistance longitudinal crack

摘要

PROBLEM TO BE SOLVED: To provide a wire for hot dipped steel wire, having high strength and excellent in longitudinal crack resistance at the time of twisting. ;SOLUTION: This wire is a wire for hot dipped steel wire, composed of a steel which contains, by mass, 0.7-1.2% C, 0.5-2.0% Si, 0.2-2.0% Mn, 0.01-0.05% Al, and 30-150ppm N and in which the amount of solid-solution N is regulated to ≤10ppm. Further, it is recommended that Cr is incorporated by 0.1-1.0% from the standpoint of the improvement of strength and workability.;COPYRIGHT: (C)1997,JPO
