Abstract (en)
[origin: WO2011092905A1] A wire material comprising 0.95 to 1.30 mass% of C, 0.1 to 1.5 mass% of Si, 0.1 to 1.0 mass% of Mn, 0 to 0.1 mass% of Al, 0 to 0.1 mass% of Ti, 0 to 0.02 mass% of P, 0 to 0.02 mass% of S, 10 to 50 ppm of N, 10 to 40 ppm of O, and the remainder containing at least Fe and unavoidable impurities, wherein 97% or more of the area of a cross-sectional surface perpendicular to the length-wise direction of the wire material is occupied by a pearlite structure, and wherein both a 0.5% or less of the area of the center region of the cross-sectional surface and 0.5% or less of the area of a first surface layer region of the cross-sectional surface are occupied by a pro-eitectoid cementite structure.
