摘　　要：球墨铸钢具有高碳钢和球墨铸铁组织的特点,是一种兼顾高碳钢和球墨铸铁性能的特殊工程材料。文中介绍了球墨铸钢的化学成分、常用合金元素及其作用、显微组织特点、力学性能、摩擦磨损性能和热疲劳性能,指出了球墨铸钢的组织和性能特点及其应用前景,并介绍了球墨铸钢在热轧辊上的应用。Spheroidal graphite cast steel, a kind of special engineering materials, has characteristics of high carbon cast steel and spheroidal graphite cast iron in the microstructure and properties. The chemical composition, including commonly used alloy elements and their role in the steel, microstructure, mechanical properties, wear resistance and thermal fatigue property of the spheroidal graphite cast steel were summarized. Due to its special microstructure and properties, the spheroidal graphite cast steel is expected to be a kind of proper materials for hot work rollers. And some relative applications are also introduced.
