The result showed the difference of mechanical properties of hsla steel results from the troostite and banded structure which are closely relative to mamgamese content 结果表明屈氏体组织以及带状组织是造成低合金钢板强度、塑性差异主要原因，而屈氏体组织、带状组织的产生和锰含量有很大关系。

The anti - wearing property of chme steel is 15 percent to 35percent higher than zgmnl3 , which is a widely used anti - wearing steel . the reason of the excellent mechanical properties and anti - wearing property of chme steel is that the heat treatment sturcture of chme steel is composed of tempered martensite , bainite , temper troostite , remaining austenite and carbonide 磨面分析表明， chme钢基体高强度，高硬度、良好的强韧性配合和碳化物硬质点的弥散分布，磨痕细短浅小，挤塑变形区细小均匀，抵抗冲击滑动累积塑性疲劳能力强，是其耐磨性比zgmn13高的原因。
