介绍了韶钢低碳拉丝用钢抗拉强度偏高的情况，分析表明钢中微量元素铜、砷、锡含量高是导致低碳拉丝用钢强度高的主要因素。为降低钢的强度，进行了成分与性能的优化试验，试验研究结果表明，在适当降低钢中微量元素的情况下，钢中的锰含量平均由原来的0.47%降低到0.25%以下后，能有效解决抗拉强度高的问题，且钢材加工使用性能良好。
Low carbon steel for wire drawing has higher tensile strength in SGIS. The analysis showed that higher tensiles strength was mainly originated from the high content of Cu, As, Sn in steel. In order to decrease tensile strength of steel, the optimization was carried out on properties and composition. The results showed when the average Mn content of steel has been lowered from 0.47% to below 0.25%, the problem of higher tensile strength is resolved on condition of appropriate reduction of trace elements, and thus process performance of low carbon stee1 are improved.
