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
