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
