摘　　要：综述了中铬钢研发与应用的进展。中铬钢在使用中不断裂、不变形、耐磨损,使用寿命是Mn13的2倍以上,适用于冲击磨料磨损工况。同时介绍了一种多元合金中铬耐磨钢,该耐磨钢的强韧性和抗冲击磨料磨损性能均高于ZG30Cr5Mo中铬钢。Application and research of medium Cr steels are introduced in the paper. Medium Cr alloy steels are wear resistant materials. They are characterized by good wear resistance, non-fracture and non-deformation in use. As compared with 13% Mn steel parts, the service life of medium Cr steels parts is two times over of it. The steel is applicable to impact attrition wear. And a new type of medium Cr wear resistant steel with other alloy elements, which has higher strength, toughness and impact abrasive wear resistance than ZG30Cr5Mo steel, is introduced.
