Study on Quenching Process of Cr12Mo1V1 Cold-rolled Work Roll
The microstructure and properties of Cr12Mo1V1 steel after quenching at different temperature and then oil-cooling were researched by impact test,hardness test,metallographic,XRD and other means.The results show that: in a certain temperature range,the impact toughness of Cr12Mo1V1 steel rises after a decline,and the hardness first rises and then falls.Ultimately,the best quenching temperature of Cr12Mo1V1 steel is 1020 ℃.
