After quenching, 9Cr 18Mo has high hardness and wear resistance, and good dimensional stability at high and low temperatures. It is suitable for manufacturing bearings in corrosive media such as seawater, river water, nitric acid, steam and oceanography, such as bearings in ships and submersible pumps, bearings in petrochemical machinery and bearings in navigation instruments.
The chemical composition of 9Cr 18Mo is as follows:
