Abstract The speedup of China’s railways since the 1990’s and the launch of today’s “Fuxing” Chinese standard EMUs was introduced. In order to meet the development of China’s high-speed railways，Masteel has conducted a series of research work on the high-speed wheel，including the independent component design，the non-metallic inclusion control，and the manufacturing processes optimization，etc. The quality of the wheel made by Masteel was better than that of imported products. The service performance of the manufactured wheel was comprehensively evaluated by loading applications，and a system-wide R&D closed loop from product research to application was finally formed，supporting the development of China’s passenger speed from less than 80 km/h to 350 km/h or more. In the above，Masteel has realized the independence of the high-speed wheel technology and the localization of products. At the same time，we have also looked ahead to Masteel’s next step in the development of high-speed wheel product categories and market developments.
