• Gears subjected to high stresses, diverse parts subject to wear and fatigue in service.
• In the quenched and tempered condition: safety-critical parts.
• 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 in order to minimise distortion due to the heat treatment.
