13. SKD11 (SLD) - nondeformation toughness high chromium steel

Due to the increase of Mo and V content in the steel, the casting structure in the steel is improved, the grain size is refined, and the carbide morphology is improved. Therefore, the strength and toughness (bending strength, deflection, impact toughness, etc.) of this steel is higher than skd1 and D2, the wear resistance is also increased, and it has a higher resistance to tempering Practice has proved that the service life of this steel die is higher than that of Cr12MoV It often manufactures high demand molds, such as drawing molds, molds for impacting grinding wheel blades, etc.

14. DC53 high toughness high chromium steel

Produced in Datong, Japan, the heat treatment hardness is higher than skd11 After tempering at high temperature (520-530), it can reach 62-63hrc high hardness, and DC53 exceeds SKD11 in strength and wear resistance The toughness is twice that of SKD11 The toughness of DC53 seldom shows cracks and cracks in cold working die manufacturing The service life is greatly improved Small residual stress Reduce residual stress by turning back at high temperature Because the cracks and deformation after wire cutting are restrained Machinability and abrasiveness exceed SKD11 Used for precision stamping die, cold forging, deep drawing dies, etc.

15. Skh-9 - general-purpose high-speed steel with high wear resistance and toughness

It is produced by Hitachi in Japan and used for cold forging dies, Slitter, drill bits, reamers, punches, etc.

16. Asp-23 - powder metallurgy high-speed steel

Made in Sweden, carbide distribution is very uniform, wear resistance, high toughness, easy to process, and heat treatment size stability It is used for punch, deep drawing die, drilling die, milling cutter, shear blade, and other long-life cutting tools.

17. P20 - plastic molds of general requirements

Made in the United States, it can be operated by an electric erosion Factory pre-hardened hb270-300 Quenching hardness hrc52.

18. 718 - plastic molds with high requirements

19. NAK80 - high mirror, high precision plastic mold

Made in Datong, Japan, pre-hardened hb370-400 Quenching hardness hrc52.

20. S136 - corrosion-resistant and mirror-polished plastic mold

Made in Sweden, pre-hardened HB ＜ 215 in ex-factory state Quenching hardness hrc52.

21. H13 - common die casting die

For die casting of aluminum, zinc, magnesium, and alloys Hot stamping die, aluminum extrusion die.

22. SKD61 - advanced die casting die

The service life of the product made by Hitachi in Japan is significantly longer than that of H13 by electro slag remelting technology Hot stamping die, and aluminum extrusion die.

23. 8407 - advanced die casting die

Made in Sweden, hot stamping die, aluminum extrusion die.

24. Fdac - sulfur is added to enhance its capability

The factory pre-hardening hardness is 338-42hrc, which can be directly engraved without quenching and tempering Used for small-batch mold, simple mold, all kinds of resin products, sliding parts, mold parts with short delivery time Zipper mold, glasses frame mold.
