| Abstract: | The microstructure, mechanical properties and carburized behavior of 18CrMn2SiMo carburizing gear steel were studied. The results show that the microstructure of 18CrMn2SiMo steel,after tempering at low temperature and air cooling, is high carbon martensite and retained austenite in carburized layer, and bainite ferrite and austenite in non carburized area. The gear made of 18CrMn2SiMo steel has excellent carbufization properties and good combination of strength and toughness. In addition,the application of 18CrMn2SiMo steel in the field of heavy gear was introduced. |
