Uddeholm Stavax ESR
VERY GOOD POLISHABILITY
Uddeholm Stavax ESR is a through hardening corrosion resistant mold steel, with very good polishability.
- Low mold 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 mold life, ensuring consistent cycle times
- Long life mold
- Good corrosion resistance
- Good polishability
- Good wear resistance
- Good machinability
- Good stability in hardening
- Corrosion resistance 80%
- Wear resistance 70%
- Polishability 90%
- Toughness 50%
