The Original Stainless Steel
The classical mould steel Stavax ESR, is a premium stainless tool steel offered by ASSAB. It is safe to say that Stavax ESR has become an industry reference and one of the absolute best-sellers within the ASSAB group of companies.
Stavax ESR has the following properties:
- good corrosion resistance
- excellent polishability
- good wear resistance
- good machinability
- good stability in hardening
The combination of these properties gives steel with outstanding production performance. The practical benefits of good corrosion resistance in a plastics mould is principally lower mould maintenance costs and lower production costs. These are the effects from the fact that the surface of cavity impressions retains their original finish over extended running periods as well as the corrosion resistance, heat transfer characteristics ensuring consistent cycle times.
These benefits, coupled with the high wear resistance of Stavax ESR, offer the producer low-maintenance, long-life moulds for the greatest overall moulding economy. Stavax ESR is produced using the Electro-Slag-Refining (ESR) technique, resulting in very low inclusion content.
