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 mould maintenance costs:
    • The surface of cavity impressions retain their original finish over extended running periods.
    • Moulds 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 mould life, ensuring consistent cycle times.
  • Safe mould 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

Plastic moulding

  • Moulds for corrosive plastics
  • Moulds requiring high surface finish
  • Big moulds requiring corrosion resistance

Components

  • Meat processing knives
  • Animal feed dies
  • General purpose stainless components

Plastic moulding

  • Corrosion/staining resistance, i.e. for moulding of corrosive materials, e.g. PVC, acetates, and for moulds subjected to humid working/storage conditions
  • High surface finish, i.e. for production of optical parts, such as camera sunglasses lenses, and for medical components, e.g. syringes, analysis vials etc.
  • Toughness/ductility, i.e. for complex moulds
  • Outstanding through-hardening characteristics i.e. high-hardenability, important for larger moulds

Components

  • Meat processing knives
  • Animal feed dies
  • General purpose stainless components
