Uddeholm Mirrax ESR

A UNIQUE COMBINATION OF TOUGHNESS, CORROSION RESISTANCE AND THROUGH-HARDENING PROPERTIES

Uddeholm Mirrax ESR is a through hardening corrosion resistant steel with very good polishability. Mainly intended for medium to large cross sections. It has a unique combination of toughness, corrosion resistance and through-hardening properties.
  • Low mold maintenance costs:
    • The surface of cavity impressions retain their original finish over extended running periods
    • Molds stored or operated in humid conditions require less protection
  • Low production costs:
    • Water cooling channels are less affected by corrosion
    • Heat transfer characteristics, and therefore cooling efficiency, are constant throughout the mold life, ensuring consistent cycle times
  • Safe mold use because of good toughness also in big dimensions
  • Good corrosion resistance
  • Excellent through-hardening properties
  • Good ductility and toughness
  • Good wear resistance
  • Excellent polishability
