CORRAX is a precipitation hardening steel with extremely good corrosion resistance and easy to heat treat. It is used both as mould material and engineering material.

  • Good corrosion resistance for moulding of corrosive plastics
  • With an easy heat treatment a higher hardness can be achieved with predictable dimensional change
  • No need for preheating at welding
  • Easier to grind and polish as no EDM layer is present
  • Extremely good corrosion resistance
  • Flexible hardness at ageing
  • Good dimensional stability
  • Uniformity of properties
  • Very good weldability
  • No EDM layer


  • Corrosion resistance 95%
  • Wear resistance 50%
  • Polishability 70%
  • Toughness 70%
