Last time, we gave some introduction about machining and mold metal material properties. Now, more kinds of materials for sharing.
About introduction of part 1, please click here.
9, DC53 - Japanese imports of cold work die steel
Features and Applications: High strength and toughness cold work die steel, Japan Datong special steel (strain) manufacturer steel. After high temperature tempering, it has high hardness, high toughness, and good wire cutting. For precision cold stamping dies, drawing dies, reeling dies, cold dies, punches, etc. 10, SM45 - ordinary carbon plastic mold steel (Japanese steel S45C)9, DC53 - Japanese imports of cold work die steel.

10, DCCr12MoV - wear-resistant chrome steel
Made in China. Compared to Cr12 steel with low carbon content and addition of Mo and V, carbides are not evenly improved, MO can reduce carbide segregation and improve hardenability, V can refine grains and increase toughness. This steel has high Hardenability, cross section below 400mm can be completely hardened, can still maintain good hardness and wear resistance at 300 ~ 400 °C, higher toughness than Cr12, small change in volume when quenched, and high wear resistance Good overall mechanical properties. So it is possible to manufacture various molds with large cross-sections, complex shapes and large impacts, such as ordinary drawing dies, punched dies, dies, blanking dies, trimming dies, piping dies, wire drawing dies. , Cold extrusion die, cold cutting scissors, circular saws, standard tools, measuring tools, etc.
11, SKD11 - toughness chrome steel
Japan Hitachi plant production. Technically improve the casting structure in the steel, refine the grain. Compared to Cr12mov's toughness and wear resistance has been improved. Extend the life of the mold.
12, D2 - high carbon high chromium cold working steel
Made in the United States. Has high hardenability, hardenability, wear resistance, high temperature oxidation resistance, good resistance to rust after quenching and polishing, heat treatment deformation is small, should produce a variety of cold work molds that require high precision, long life , Tools and measuring tools, such as drawing die, cold extrusion die, cold shearing knife, etc.
13, SKD11 (SLD) - non-deformation tough high chromium steel
Japan Hitachi Plant Production. As the content of MO, V in the steel increases, the cast 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) of the steel are improved. Such as) higher than SKD1, D2, wear resistance has also been increased, but also has a higher resistance to tempering. Practice has shown that this steel mold life than Cr12mov has increased. Often required to make high mold, such as tensile die, impact Grinding wheel die and so on.
14, DC53 - high toughness high chromium steel
Japan Tatung Co., Ltd. production. Heat treatment hardness higher than SKD11. High temperature (520-530) After tempering up to 62-63HRC high hardness, in strength and wear resistance DC53 more than SKD11. Toughness is twice that of SKD11. DC53 toughness in Cold working molds produce few cracks and cracks. The service life is greatly improved. The residual stress is small. The residual stress is reduced at high temperatures. The cracks and deformations after wire cutting are suppressed. Machinability and abrasiveness exceed that of SKD11. Precision stamping die, cold forging, deep drawing die, etc.
15, SKH-9 - wear resistance, high toughness of general purpose high-speed steel
Japan Hitachi Corp. Production. Used for cold forging die, cutting machine, drill, reamer, punch and so on.
16, ASP-23 - powder metallurgy high speed steel
Made in Sweden. Very uniform distribution of carbides, wear resistance, high toughness, easy processing, dimensional stability of heat treatment. Used for various long-life cutting tools such as punches, deep drawing dies, drilling dies, milling cutters and shearing blades.
17, P20 - General requirements of the size of plastic mold
US-made. Erosion operation. Pre-hardened HB270-300. Hardened hardness HRC52.
18, 718 - High-demand plastic mold
Made in Sweden. Electro-erosion operation in particular. Pre-hardened HB290-330. Hardened Hardness HRC52
19, Nak80 - high mirror, high precision plastic mold
Japan Tatung Co., Ltd. Factory Pre-hardened HB370-400. Quenched Hardness HRC52
20, S136 - anti-corrosion and mirror polishing plastic mold
Made in Sweden. Pre-hardened HB<215. Hardened Hardness HRC52.
21, H13 - common die casting mold
For aluminum, zinc, magnesium and alloy die-casting. Hot stamping die, aluminum extrusion die.
22, SKD61 - Advanced Die Casting Die
Japan's Hitachi plant type production, re-dissolved by electrolysis technology, in the service life than H13 has significantly improved. Hot stamping die, aluminum extrusion die.
23, 8407 - Advanced Die Casting Die
Made in Sweden. Hot Stamping Dies, Aluminum Extrusion Dies.
24, FDAC - adding sulfur to enhance its easy machinability
Factory pre-hardness 338-42HRC, can be carved directly processing, no quenching, tempering. Used in small batch mold, simple mold, various resin products, sliding parts, short delivery time mold parts. Zipper mold, Spectacle frame model.
