Product description
ASSAB ASSAB STAVAX ESR (S-136) is a high-grade stainless steel tool steel that has following characteristics:
●Excellent corrosion resistance
●Excellent polishability
●Excellent wear resistance
●Excellent machinability
●Excellent stability during quenching. Combining advantages listed above, this steel grade has excellent production characteristics. Due to its excellent corrosion resistance, benefits of using it in plastic molds are summarized as follows: 　
●Lower maintenance costs. After long-term use of mold, surface of mold cavity still maintains original smooth state. When mold is operated or stored in a humid environment, no special protection is required.
●Lower production cost. Because mold cooling channel is not affected by corrosion (unlike ordinary mold steel), heat transfer characteristics and cooling efficiency remain stable during life of mold, ensuring mold's permanent forming time. STAVAXESR (S-136) is recommended for all plastic molds. Due to its special nature, it is more suitable for needs of special environments.　　●Corrosion and rust resistance to use of corrosive PVC, acetate and other injection molding materials or molds that must be worked and stored in a humid environment.
●Abrasion resistance. When using large-wearing injection molding materials (including thermosetting injection molding molds) or requiring molds to have a long working time, such as electronic parts, disposable tableware, utensils, etc.　　
●High-smooth surfaces produce optical products, such as cameras, sunglasses, chemical instruments and plastic products.
Features: Excellent polishing performance, good corrosion resistance.
