Along with the rapid development of the science and technology, the requirements of microstructure and properties for the bearing steel are more and more strict. The recrystallization behavior of hot deformed austenite in GCr15 bearing steel was systematically studied under the different deformation amount, deformation temperature and dwell time after rolling, the changes of microstructure and recrystallization percentage was analyzed. The research results show that the recrystallization behavior of hot deformed austenite in GCr15 bearing steel is more and more obvious as the deformation amount, deformation temperature and dwell time after rolling increase, the microstructure is more uniform, and the recrystallization percentage increases; When the deformation amount is 20%, the deformation temperature is 850°C and the dwell time after rolling is 10s, the recrystallization percentage is 32.09%, when the deformation amount is 45%, the deformation temperature is 950°C and the dwell time after rolling is 60s, the recrystallization percentage is 64.31%, comparing it to 32.09%, it increases 100.4%.
