1铬对钢组织的影响铬是一种碳化物形成元素。在金属材料中，它能与碳生成Cr3C等金属化合物，而这种金属化合物具有较高的强度、硬度。当它以颗粒状弥散性分布在金属基体上时，能大大提高材料的强度、韧性、耐磨性。2铬阻碍奥氏体晶粒长大除锰以外，所有合金元素都能阻碍加热时 1 chromium on the impact of chromium is a carbide forming element. In metal materials, it can form Cr3C with carbon and other metal compounds, and this metal compound has high strength, hardness. When it is distributed in granular dispersion on the metal matrix, can greatly improve the strength of the material, toughness, wear resistance. 2 Chromium hinder austenite grain growth In addition to manganese, all the alloying elements can hinder heating
