Effect of the Carburizing Process on the Microstructure and Properties of 18CrNiMo7-6 Steel
High-temperature carburizing heat treatment of 18CrNiMo7-6 steel was carried out at 930 °C, 950 °C and 970 °C. The effects of carburizing process on the microstructure, hardness and wear resistance of 18CrNiMo7-6 steel were studied. The results showed that the microstructure after high-temperature carburizing was mainly tempered martensite, and there ...
