ASSAB Stavax ESR
Stavax ESR is a premium grade stainless tool steel with the following properties:
- good corrosion resistance
- excellent polishability
- good wear resistance
- good machinability
- good dimensional stability during heat treatment
The combination of these properties gives a steel with outstanding production performance. The practical benefits of good corrosion resistance in a plastics mould can be summarized as follows:
- Lower mould maintenance costs: The surface of cavity impressions retain their original finish over extended running periods. Moulds stored or operated in humid conditions require no special protection.
- Lower production costs: Since water cooling channels are unaffected by corrosion (unlike conventional mould steel), heat transfer characteristics, and therefore cooling efficiency, are constant throughout the mould life, ensuring consistent cycle times.
Note: Stavax ESR is produced using the Electro-Slag-Refining (ESR) technique, resulting in a very low inclusion content.
Applications
Whilst Stavax ESR is recommended for all types of moulding tools, its special properties 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 sunglasses lenses, and for medical containers, e.g. syringes, analysis phials.
