Research status and development trend of bearing steel

The continuous development of China′s industrial manufacturing field in recent years has posed new challenges to the research, development and manufacturing of domestic bearing steel. The development and production of high-quality bearing steel has become one of the urgent problems to be solved in the domestic bearing industry. The research progress of bearing steel at home and abroad is comprehensively discussed in terms of the classification of bearing steel, the main influencing factors of bearing steel performance and the development of heat treatment technology and so on. In order to realize the quantitative production and application of domestic high quality bearing steel, the methods of process optimization, control of inclusions and carbides, lack of testing equipment and technical evaluation indexes for the development of high quality bearing steel in China are put forward.
