HIGH-CARBON STEEL WIRE ROD AND PREPARATION METHOD THEREFOR

摘要

Provided are a high-carbon steel wire rod and a preparation method therefor, wherein the high-carbon steel wire rod comprises the following components: C, Si, Mn, Cr, V, Ti and Fe. The high-carbon steel wire rod has comparatively ideal mechanical properties, including not only relatively high strength but also outstanding plasticity, wherein the average tensile strength can reach 1560MPa, the average shrinkage rate after fracture is 30%, and the percentage elongation after fracture is greater than or equal to 9%. The high-carbon steel wire rod can meet the performance requirements for producing 2300MPa pre-stressed steel strands.
