S136H Mould Steel Bar
S136H is a kind of pre-hardened corrosion-resistant mirror mould steel. S136H mold steel has high purity, high mirror finish, good polishing performance, strong rust and acid resistance, small heat treatment deformation and soft annealing to about hb215 (can be hardened To hrc53) Suitable for mirror molds, high acid resistance after quenching, can ensure that the cooling pipe is not corroded, suitable for pvc, pp, ep, pc, pmma plastics, food industry machinery components. Mould steel suitable for use in humid environment and weak acid-alkaline environment, ESR remelted (Grade A) steel is suitable for making optical instruments, lenses, lens molds, disposable meal knives, utensils, cameras, sunglasses, chemistry Instruments and plastic product molds, etc.

S136H advantages:
Lower maintenance costs:
After long-term use of the mould, the cavity surface remains the original smooth state. No special protection is required when the mold is operated or stored in wet conditions.
Lower production costs:
Mold is not due to the impact of cooling water and corrosion, due to a certain cooling cycle, increase mold life. The benefits listed above, combined with the high wear resistance of the S136H, provide low maintenance costs and high life molds for optimum economics. At the same time S136H after "ESR" refining, with pure and subtle organization, the mold has a very good overall mechanical properties, high polishing performance.
