摘　　要：以A3废钢为主要原料,添加Si,Mn,Cr,Cu等多种微量合金元素,加入少量Mo、稀土进行微合金化和变质处理,在空冷条件下,获得了综合性能优良的贝氏体钢.主要研究了该钢的成分、组织和性能之间的关系.结果表明,低合金空冷贝氏体钢的生产工艺简单,贵重合金元素加入量少,生产成本低,具有优良的强韧性和耐磨性,综合效益显著.Scrap A3 steel,containing suitable Si,Mn,Cr and trace amount of Mo and rare earth（RE）,was taken as the main raw material for multi-element low-alloy air-cooled bainitic steel.It has high hardness and toughness in air quenching state.In this paper,the relationships of the composition,structure and properties of this kind of steel were researched.The multi-component low alloy bainitic steel has a simple production technology,less addition of valuable alloy and low production cost,high hardness and toughness and excellent wear-resistance.It will increase economic benefits significantly.
