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
