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
