Document Type and Number:
WIPO Patent Application WO/2019/164015
Kind Code:
A1
Abstract:
This wire rod has a chemical composition containing, in mass%, 0.80-1.10% of C, 0.005-0.100% of Si, 0.05-0.30% of Mn, 0-0.030% of P, 0-0.030% of S, 0-0.0060% of N, not less than 0.02% but less than 0.30% of Cr, 0.02-0.15% of Mo, 0-0.050% of Al, 0-0.050% of Ti, and 0-0.0030% of B, the balance being Fe and impurities, and the total amount of Mo and Cr being 0.13% or more, wherein the average area ratio of a pearlite structure in a region within d/7 from the center of the wire rod and a region within d/7 from the peripheral surface of the wire rod is 90% or more in a cross-section perpendicular to the longitudinal direction of the wire rod, where d represents the diameter of the wire rod. This steel wire is obtained by subjecting the wire rod to a drawing process. This aluminum-coated steel wire is obtained by coating the steel wire with an aluminum-containing layer.
