STEEL WIRE WITH EXCELLENT WIRE DRAWABILITY

PROBLEM TO BE SOLVED: To improve the wire drawability of a steel wire without applying patenting treatment. SOLUTION: The steel wire is a plated steel wire and characterized in that: the steel has a component composition consisting of, by mass, 0.35 to 0.90% C, 0.1 to 0.4% Si, 0.2 to 1.1% Mn, ≤0.04%...

Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the wire drawability of a steel wire without applying patenting treatment. SOLUTION: The steel wire is a plated steel wire and characterized in that: the steel has a component composition consisting of, by mass, 0.35 to 0.90% C, 0.1 to 0.4% Si, 0.2 to 1.1% Mn, ≤0.04% (not including 0%) P, ≤0.04% (not including 0%) S, ≤0.005% (not including 0%) Al and the balance iron with inevitable impurities and also has a structure in which carbides observed in a steel cross-section in a position at a depth of D/4 (D:wire diameter of steel wire) satisfy [(the number of spheroidal carbides)/(the number of carbides)]×100≤65.
