Uddeholm Stavax ESR

Uddeholm Stavax ESR is a premium stainless mould steel for small and medium inserts and cores. Uddeholm Stavax ESR combines corrosion and wear resistance with excellent polishability, good machinability and stability in hardening.

Mould maintenance requirement is reduced by assuring that core and cavity surfaces retain their original finish over extended operating periods. When compared with non stainless mould steel, Uddeholm Stavax ESR offers lower production costs by maintaining rust free cooling channels, assuring consistent cooling and cycle time.

This classic stainless tool steel is the right choice when rust in production is unacceptable and where requirements for good hygiene are high, as within the medical industry, optical industry and for other high quality transparent parts.

Uddeholm Stavax ESR is a part of the Uddeholm Stainless Concept.

Benefits

• 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, and therefore cooling efficiency, are constant throughout the mould life, ensuring consistent cycle times.
• Long life mould
