Material Specifications
Applications
- Gears subjected to high stresses
- Diverse parts subject to wear and fatigue in service
- In the quenched and tempered condition: safety-critical parts
Characteristics
- High mechanical properties
- Good fatigue strength
- After carburising, quenching and tempering, the surface hardness is around 730 HV
- Good toughness of the carburised layer
- For some carburising applications, oil quenching can be replaced with gas pressure quenching to minimise distortion
