随含碳量的增加，低合金耐磨钢热处理后的组织逐渐由板条马氏体转变为板条马氏体＋片状马氏体混合组织，且片状马氏体的数量增多，同时，二次碳化物增加，导致该材质的硬度增加，冲击韧性下降。其三体冲击磨损耐磨性需要较高硬度与良好韧性的配合。在中等冲击载荷条件下，中碳低合金耐磨钢具有最佳的冲击磨损耐磨性，可以作为锤式破碎机锤头和球磨机衬板的材质
With the increase of carbon content, the microstructure of low-alloy wear-resistant steel after heat treatment gradually transformed from lath martensite to lath martensite and lamellar martensite mixed structure, and the number of lamellar martensite increased , Secondary carbides increase, resulting in increased hardness of the material, impact toughness decreased. The three-body impact wear resistance requires high hardness and good toughness. Medium impact load conditions, carbon low-alloy wear-resistant steel with the best impact wear resistance, can be used as hammer crusher hammer and ball mill liner material
