Abstract

A wire material having a tensile strength of 900 to 1300 MPa and adapted for use in manufacturing a non refined machine component wherein the wire material contains 0.20 to 0.50 wt% of C 0.05 to 2.0 wt% of Si and 0.20 to 1.0 wt% of Mn; is limited to 0.030% or less of P 0.030% or less of S and 0.005% or less of N; and has less than 0.60 of F1 defined by expression (1) the balance comprising Fe and inevitable impurities. A metallographic structure includes 64×(C%)+52% or more of a pearlite structure by volume and the balance comprises one or two types of a pro eutectoid ferrite structure and a bainite structure. Designating the diameter of the wire material as D the average block particle diameter of the pearlite structure in the region from the surface layer to 0.1D is 15 µm or less and (the average block particle diameter of the pearlite structure in the region from the surface layer to 0.1D)/(the average block particle diameter of the pearlite structure in the range from 0.25D to the center) is less than 1.0. F1 = C(%)+Si(%)/24+Mn(%)/6 ... (1)
