Bohler-Uddeholm UDDEHOLM MIRRAX ESR Plastic Mold Steel
Categories: Metal; Ferrous Metal; Tool Steel; Mold Steel

Material Notes: Uddeholm Mirrax ESR is specially developed and adapted for larger molds that require corrosion resistance and/or high surface finish.

It is characterized by:

  • High hardenability for consistent properties in large dimensions
  • Good ductility and toughness for a safe production
  • High corrosion resistance for low maintenance requirements
  • Excellent polishability for aesthetic quality and function
  • Good wear resistance for longer life
Uddeholm Mirrax ESR is also the right choice for larger tools when contamination in production is totally unacceptable: within the medical industry, optical industry and for other high quality transparent articles.

Applications: Although Uddeholm Mirrax ESR is recommended for all types of moulds, its special properties make it particularly suitable for molds with the following demands:

  • 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 the production of optical parts, such as camera and sunglass lenses, and for medical components, e.g. syringes, analysis vials etc..
  • Toughness/ductility, i.e. for complex molds
  • Outstanding through-hardening characteristics i.e. high-hardenability, important for larger molds.

Key Words: AISI 420 Modified; W.-Nr. 1.2083
