Typical Applications
This steel is widely used in transmission systems, tractor motors, and small to medium automotive applications. It serves as an alternative to 12CrNi3 for higher-class carburization and cyanide carburizing parts including:
- Oil drilling components
- Mining claws and cones
- Carburized gears and pinions
- Shafts and bearings
- Piston rings and ring gears
- Crankshafts
