The effects of varying the amount of secondary carbide on the character of matrix under three-body abrasion of wear resistantsteel have been investigated.
选用三种不同碳、铬含量的耐磨钢，通过热处理获得不同数量的二次碳化物和马氏体基体。

The axle center adopts special abrasionresistantsteel materials, which is firm, stable and durable.
轴心采用特殊耐磨钢材、牢固稳定、经久耐用。
