Uddeholm Corrax


Uddeholm Corrax is a precipitation hardening steel with a unique set of properties that makes it perfect for many demanding applications. The superior resistance against corrosion combined with a hardness up to 50 HRC and a simple heat treatment makes Uddeholm Corrax the obvious choice for long run series of aggressive plastics such as PVC.

The chemical composition makes Uddeholm Corrax easy to process by additive manufacturing. Hence, it is also available as powder for Laser Powder Bed Fusion (LPBF) and Laser Metal Deposition (LMD).

Uddeholm Corrax is characterized by:

  • Very good corrosion resistance
  • Flexible hardness of 34-50 HRC achieved by ageing
  • No hard “white layer” after EDM
  • Very good corrosion resistance
  • Uniformity of properties
  • Very good weldability
  • No EDM layer
  • Flexible hardness 34–50 HRC
  • Easy to process by AM technologies
  • Sustainable tool steel: 84,5% recycled content
