<p>Provided is a wire material which contains 0.6-1.1 mass% C, 0.1-0.5 mass% Si, 0.2-0.6 mass% Mn, 0.004-0.015 mass% S, and 0.02-0.05 mass%, excluding 0.05 mass%, Cr, the remainder comprising Fe and incidental impurities in which the P and Al contents have been reduced to 0.02 mass% or lower and 0.003 mass% or lower, respectively. The wire material has a pearlite structure in the surface. In a cross-section of the wire material, the crystal planes of the ferrite in the pearlite structure include {110} planes in the peripheral part, the {110} planes having a degree of accumulation of 1.2 or higher.</p> |
