In this paper, based the actual application condition of domestic and international brake disc for high-speed train, the low-alloy cast steel of the brake disc for high-speed train is developed. The chemical composition, melting and casting processes as well as heat treatment technology of disc material are studied. The new low-alloy cast steel has the ideal metallographic microstructure, proper physical and mechanical properties. The tensile strength is more than 1100Mpa in 20°C condition, the impact energy value (Aku2) is more than 8J in-60°C condition. The test results show the new low-alloy cast steel developed can meet the brake disc performance requirements for 380km/h high-speed train.
