9Crl8 9Crl8Mo
It has high hardness and tempering stability, good machinability and cold stamping, and poor thermal conductivity. Quenching cold treatment and low temperature tempering have higher mechanical properties
It is used to manufacture corrosion-resistant bearing rings and rolling elements, such as bearings for seawater, river water, nitric acid, chemical petroleum, and atomic reactors. It can also be used for corrosion-resistant high-temperature bearing steels, and its working temperature is not higher than 250 °C; Manufacture of high quality tool medical scalpels, mechanical parts with low wear resistance and corrosion resistance but low dynamic load
