【Abstract】 This paper deals with the carburizing process,microstructure,mechanical properties and quenching distortion of the air cooling low carbon bainitic steel.The test results show that the low carbon bainitic steel has good performance of carburizing process,mechanical properties and good microstructure.After carburizing and gas quenching of the low carbon bainitic steel gear,its quenching distortion is obviously lower than that of 20CrMnTi steel.更多还原
