4. Supply states: 30-36HRC
5. Features
1) Good corrosion resisting
2) High cast polarimetry
3) Good wear resistance
4) Excellent machining property
5) Quenching with excellent stability
6. Advantages
1) The mold manipulation or storage in humid environment, do not need special protection.
2) Lower production costs due to the mold cooling water from corrosion (unlike ordinary tool steel), heat transfer characteristics, cooling efficiency during the lifetime of the mold to maintain stability and ensure the constancy of the forming die time.
3) STAVAX ESR (S-136) is recommended for all molds, due to its special nature, it is more suitable for the needs of specific environments.
4) Resistant injection molding material or work and must be stored in a wet environment, mold corrosion, rust on the use of corrosive PVC, acetic acid salts.
5) Abrasion wear resistance using large injection molding material (including thermoset injection molding) or the requirements of the mold have longer working hours, such as electronic parts, discard-style meal knives, and other utensils.
6) High surface smoothness of the production of optical products such as cameras, sunglasses, chemical equipment and plastic products.
