摘　　要：对铸钢20SiMnCrMo的成分及其组织性能进行了研究,分析了合金元素间交互作用形成的组织及其力学性能。结果表明,20SiMnCrMo高强度耐磨钢的化学成分表现为较低含量的碳和新的合金元素配比;20SiMnCrMo铸钢的晶粒度为9级,硬度、强度和塑性及冲击韧性等综合力学性能较好。The chemical composition, microstructure and properties of cast steel 20SiMnCrMo were researched. The microstructure and interaction between alloy elements were analyzed. The results show that the chemical composition of 20SiMnCrMo cast steel is low carbon content and a new mixture ratio of alloying element. The grain size of the steel is grade 9, which is better than that of ordinary GM materials.The mechanical property is better, such as hardness, intensity, plasticity and impact toughness and so on.
