Grade Brief
Stavax ESR is a premium-grade stainless tool steel, produced by the Electro-Slag Remelting (ESR) process, which ensures a very pure, homogeneous microstructure with excellent polishability. It is primarily used for plastic mould applications where corrosion resistance, mirror finish, and consistent performance are required.
Key Features
- Excellent corrosion resistance (rust-free cooling channels, lower maintenance cost).
- High mirror polishability – suitable for optical lenses, medical components, and high-gloss moulds.
- Good wear resistance compared to standard stainless steels.
- Stable in hardening, offering dimensional stability
- Lower production cost by maintaining consistent cooling and cycle times

Key Characteristics
Application
Plastic moulds for acidic/corrosive plastics (PVC, acetates, thermoplastics with flame retardants), Moulds requiring mirror-finish surfaces (optical lenses, medical devices, cosmetic packaging), Components exposed to humid or corrosive environments, Small and medium-sized mould inserts and cores.
Conclusion
Stavax ESR (1.2083 / AISI 420) stainless mold steel is a high-quality ESR-refined tool steel designed to withstand challenging mold-making service. Its high corrosion resistance, high polishability, and predictable hardening behavior guarantee long performance and low maintenance cost. Its mirror-quality finish capability also makes it the material of choice in medical devices, optical lenses, cosmetic packaging, and other moulds that have high gloss. Stavax ESR, a choice based on durability, wear resistance, and dimensional stability, is a reliable choice in manufacturing high-precision moulds in an industry where performance and surface quality are paramount.
