摘　　要：为满足某些行业对球磨机衬板性能的苛可要求,设计了一组综合性能较好的低碳CrNiMnMo合金衬板钢。通过改变部分合金元素(Ni、Mn)含量,考察了两种衬板钢性能的改变。结果表明:两种衬板钢的组织均为单相马氏体,高镍低锰合金衬板钢硬度不及低镍高锰合金衬板钢,而冲击韧性和耐腐蚀性优于低镍高锰合金衬板钢,其冲击腐蚀磨损综合性能优于低镍高锰合金衬板钢。A series of CrNiMnMo liner steels with good combination properties were designed to meet the hard requirement of ball mill liner in some environments.The change of properties was studied through adjusting content of alloys （Ni、Mn）. The results show that the structure of two steels are both martensite ,the hardness of high Ni low Mn liner steel is lower than that of low Ni high Mn liner steel, the impact toughness and the corrosion resistance are better. The impact corrosion wear property is also better than that of low Ni high Mn liner steel.
