摘要：
本发明公开了一种高速列车锻造用制动盘材料，该制动盘材料的组份及质量百分比（Wt%）为：C：0.16～0.25，Si：0.25～0.60，Mn：0.80～1.30，Cr：0.70～1.20，W：0.01～0.03，Ni：0.80～1.30，Mo：0.40～0.70，Cu：0.05～0.20，SiC：0.18～0.25，Al2O3：0.20～0.30，V：0.03～0.15，N：0.0050～0.025，Re：0.005～0.20，P≤0.015，S≤0.010，余量为Fe。本发明具有高耐磨性能和良好的抗热裂性能，能使高速列车实现安全可靠制动，并减少高速列车的使用和维修成本。
摘要（英）：

The invention discloses a brake disc material for forging a high-speed train. The brake disc material comprises the following components by mass percent: 0.16%-0.25% of C, 0.25%-0.60% of Si, 0.80%-1.30% of Mn, 0.70%-1.20% of Cr, 0.01%-0.03% of W, 0.80%-1.30% of Ni, 0.40%-0.70% of Mo, 0.05%-0.20% of Cu, 0.18%-0.25% of SiC, 0.20%-0.30% of Al2O3, 0.03%-0.15% of V, 0.0050%-0.025% of N, 0.005%-0.20% of Re, not more than 0.015% of P, not more than 0.010% of S and the balance of Fe. The brake disc material is high in wear resistance and good in thermal cracking resistance, the high-speed train can be safely and reliably braked, and the use and repair costs of the high-speed train are reduced.
