Uddeholm Stavax ESR


Uddeholm Stavax ESR is a through hardening corrosion resistant mould steel, with very good polishability.

  • Low mould maintenance because of corrosion resistance:
    • Surfaces retain their original finish
    • Less production during storing and operation in humid condition
  • Lower production costs:
    • Since water-cooling channels are unaffected by corrosion
    • Heat transfer characteristics, therefore cooling efficiency is constant throughout the mould life, ensuring consistent cycle times
  • Long life mould
  • Good corrosion resistance
  • Good polishability
  • Good wear resistance
  • Good machinability
  • Good stability in hardening
