高强度钢丝
摘要：
本发明涉及一种高强度钢丝，其包含规定的成分组成，在包含钢丝的中心轴且与中心轴平行的断面中，钢丝内部的珠光体组织的面积率为90％以上，钢丝表层部的珠光体组织的面积率为80％以上；在整个所述钢丝的组织中，渗碳体的平均长度在1.0μm以上的薄片状珠光体组织的面积率为30％～65％，且渗碳体的平均长度在0.30μm以下的分割珠光体组织的面积率为20％～50％；且抗拉强度为1960MPa以上。
摘要（英）：

A high-strength steel wire comprising a predetermined material composition, wherein: in a cross-section including a central axis of the steel wire and parallel to the central axis, the area ratio of pearlite structures in the steel wire is 90% or greater, the area ratio of pearlite structures in a surface layer part of the steel wire is 80% or greater, and from among the structures over the wholeof the steel wire, the area ratio of lamellar pearlite structures with an average cementite length of 1.0 [mu]m or larger is 30% to 65%, and the area ratio of fragmented pearlite structures with an average cementite length of 0.30 [mu]m or smaller is 20% to 50%; and the steel wire has a tensile strength of 1,960 MPa or greater.
