S136H S136H good introduction Sweden Assab pre-hardened steel corrosion mirror mold, high purity, high degree of mirror polishing performance. Excellent rust and acid capacity, heat deformation, suitable dry quenching defense S136H mirror mold steel mold high acidity. Can not guarantee the cooling pipe corrosion, suitable for PVC, PP, EP, PC, PMMA plastic, food and industrial machinery. Factory state and reference hardness: Pre-hardened 30-36HRC supplier annealing HR230 varieties: round, square, flat steel mold steels suitable for use in wet environments and weakly alkaline environment used by ESR remelting (A grade) steel suitable for the production of optical instruments, lenses, lens mold as applied to the sub-parts, discard-style meal knives, utensils, cameras, sunglasses, chemical equipment and plastic products chemical composition: C Si Mn Cr PS element content (%) 0. 38 13.6 0.8 0.5 <0.03 <0.03 Features ● Excellent corrosion resistance ● Excellent polishing of optical ● Excellent abrasion resistance ● Excellent machinability ● Excellent stability quenching ● corrosion resistance, rust on the use of corrosive PVC, acid salts such as injection molding and storage of raw materials or have to work in a wet environment mold. ● 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, utensils and so on. ● high surface smoothness of the production of optical products, such as cameras, sunglasses, chemical equipment and plastic products. S136 Steel Features: excellent polishing performance, good corrosion resistance high surface finish production of optical products, such as cameras, sunglasses, chemical equipment, syringes, analytical instruments and plastic products.
