本文分析了斗齿传统材料高锰钢的局限性，指出用低合金钢代替高锰钢是必然趋势。对用来制造斗齿的几种耐磨低合金钢的成分、性能及热处理工艺作了具体介绍。
This paper analyzes the limitations of traditional high manganese steel bucket teeth, pointed out that low alloy steel instead of high manganese steel is an inevitable trend. The composition, performance and heat treatment process of several kinds of wear-resistant low-alloy steel used to make bucket teeth are introduced in detail.
