摘要

The present invention relates to a wire rope which includes, as a chemical composition, by weight, 0.40% to 1.10% of C, 0.005% to 0.350% of itself, 0.05% to 0%. 90% min, 0% to 0.70% Cr, 0% to 0.070% A1, 0% to 0.050% Ti, 0% to 0.10% v, 0% to 0.050% nb, 0% to 0.20% wt and 0% to 0.0030% wt, and a remainder including fe and impurities; wherein a metal structure within a cross section includes 80% area or more of a perlite structure having lamellar cementite; a mean lamellar spacing, which is a lamellar cementite spacing, is 28 to 80 nm; an average length of lamellar cementite is 22.0 µm or less; between the perlite structure, a perlite structure having lamellar cementite, of which the inclination with respect to the longitudinal direction of the wire rope is 15 ° or less, is 40% area or more; a degree of integration in the ferrite plane {110} with respect to the longitudinal direction is in the range of 2.0 to 8.0, and a wire rope diameter is 1.4 mm or more.
