Uddeholm Mirrax® 40

Uddeholm Mirrax 40 is a remelted stainless tool steel supplied prehardened to 40 HRC. Uddeholm Mirrax 40 is produced using the electroslag remelting (ESR) process —an additional step in the steelmaking process that ensures very clean steel with low sulphur content (0.003% max.) and non-metallic inclusions. Consequently, Uddeholm Mirrax 40 is capable of being polished to a very high surface finish.

Uddeholm Mirrax 40 is characterized by:  

  • excellent machinability
  • excellent polishability
  • excellent ductility and toughness
  • uniform hardness even in large dimensions
  • good indentation resistance
  • good corrosion resistance

These properties combine to give a steel with outstanding production performance.
