Bohler-Uddeholm UDDEHOLM STAVAX® ESR Modified 420
Categories: Metal; Ferrous Metal; Stainless Steel; Tool Steel

Material Notes: Premium grade stainless tool steel

Stavax® ESR is characterized by:

  • Good corrosion resistance
  • Good polishability
  • Good wear resistance
  • Good machinability
  • Good stability in hardening
Applications: Uddeholm Stavax ESR is recommended for all types of moulding tools and its special proper­ ties make it particularly suitable for moulds 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.
  • Wear resistance, i.e. for moulding abrasive/ filled materials, including injection-moulded thermosetting grades. Uddeholm Stavax ESR is recommended for moulds with long production runs, e.g. disposable cutlery and containers.
  • High surface finish, i.e. for the production of optical parts, such as camera and sun­ glasses lenses, and for medical containers, e.g. syringes, analysis phials.

Key Words: AISI 420 modified
