9. DC53——Commonly used cold work die steel imported from Japan.Features and applications: High strength and toughness cold work die steel, Japan Datong Special Steel Co., Ltd. manufacturer's steel grade. After high temperature tempering, it has high hardness, high toughness and good wire cutting performance. Used for precision cold stamping dies, drawing dies, wire rolling dies, cold blanking dies, punches, etc.
10. DCCr12MoV——This wear-resistant chromium steel is made in China, and has a lower carbon content than Cr12 steel. Mo and V are added to improve the unevenness of carbides. MO can reduce carbide segregation and improve hardenability. V can refine grains and increase toughness. This steel has high hardenability, the cross-section can be completely hardened under 400mm, and it can still maintain good hardness and wear resistance at 300~400℃. It has higher toughness than Cr12, small volume change during quenching, and high Wear resistance and good comprehensive mechanical properties. Therefore, various molds with large cross-section, complex shapes and large impact can be manufactured, such as ordinary drawing dies, punching dies, punching dies, blanking dies, trimming dies, piping Dies, wire drawing dies, cold extrusion dies, cold cutting scissors, circular saws, standard tools, measuring tools, etc.
11. SKD11——Tough chrome steel, produced by Hitachi, Ltd., Japan.Technically, the casting structure in the steel is improved, the grains are refined, and the toughness and wear resistance of Cr12mov are improved. Extend the service life of the mold.
12. D2——High-carbon high-chromium cold-worked steel made in the United States. It has high hardenability, hardenability, wear resistance, good high temperature oxidation resistance, good corrosion resistance after quenching and polishing, and small heat treatment deformation. Measuring tools, such as drawing dies, cold extrusion dies, cold shearing knives, etc.
13. SKD11(SLD)——Non-deformable ductile high-chromium steel is produced by Hitachi, Ltd., Japan.Due to the increase in the content of MO and V in the steel, the casting structure in the steel is improved, the grains are refined, and the carbide morphology is improved, so the strength and toughness (flexural strength, deflection, impact toughness, etc.) of this steel are higher than SKD1, D2 is high, the wear resistance is also increased, and it has higher tempering resistance. Practice has proved that the life of this steel mold is higher than that of Cr12mov, and it is often used to manufacture molds with high requirements, such as stretching molds, molds for impact grinding wheels, etc. .
14. DC53——High-toughness and high-chromium steel is produced by Datong Co., Ltd., Japan.Heat treatment hardness is higher than SKD11, high temperature (520-530) tempering can reach 62-63HRC high hardness, DC53 exceeds SKD11 in strength and wear resistance, and toughness is twice that of SKD11. The toughness of DC53 shows few cracks and cracks in cold work die making. The service life is greatly improved, the residual stress is small, and the residual stress is reduced after high temperature. Because cracks and deformation after wire cutting are suppressed, machinability and abrasiveness are superior to those of SKD11. Used for precision stamping dies, cold forging, deep drawing dies, etc.
15. SKH-9——General-purpose high-speed steel with high wear resistance and toughness,Produced by Hitachi Co., Ltd., Japan. For cold forging dies, slitters, drills, reamers, punches, etc.
16. ASP-23——Powder metallurgy high speed steel made in Sweden.Carbide distribution is extremely uniform, wear resistance, high toughness, easy processing, heat treatment dimensional stability. For punches, deep drawing dies, drilling dies, milling cutters and shear blades and other long-life cutting tools.
17. P20——Generally required size plastic molds are made in the United States. Electrically erodible operation. Factory state pre-hardened HB270-300, quenched hardness HRC52.
18. 718——High-demand size plastic molds, made in Sweden. Especially in the electro-erosion operation, the factory state is pre-hardened HB290-330, and the quenching hardness is HRC52.
19. Nak80——High mirror surface, high precision plastic mold, produced by Datong Co., Ltd. in Japan. Factory state pre-hardened HB370-400, quenched hardness HRC52.
20. S136——Anti-corrosion and mirror-polished plastic moulds, made in Sweden. Pre-hardened HB<215 in factory state, quenched hardness HRC52.
21. H13——Commonly used die-casting dies for aluminum, zinc, magnesium and alloy die-casting, hot stamping dies, and aluminum extrusion dies.
22. SKD61——Advanced die-casting die, produced by Hitachi Co., Ltd. in Japan, has a significantly improved service life than H13 through ballast redissolving technology. Hot stamping die, aluminum extrusion die.
23. 8407——Premium die-casting mold, made in Sweden. Hot stamping die, aluminum extrusion die.
24. FDAC——Sulfur is added to enhance its machinability. The factory pre-hardened hardness is 338-42HRC, which can be directly engraved without quenching and tempering. It is used for small batch molds, simple molds, various resin products, sliding parts, mold parts with short delivery time, zipper molds, and eyeglass frame molds.
