D3 / 1.2080 Cold Work Special Tool Steel Bar Diameter 10-180mm
SKD1 / D3 mold steel is one of a cold work mold steel with excellent wear resistance and stability heat treatment. Widely used for deep drawing die.
The resistance welding electrode: Chromium, zirconimu, copper though the method combine with heat treatment and cold working to ensure is performance.
So that it has the best mechanical property and good physical property. high carbon,high chrome ledeburite cold work mould steel,has good hardenability characteristic and good wear resistance.
|Flat Bar Size(mm)||Round bar Size(mm)|
1. Vacuum degassing refining treatment of steel purity.
2. Spherification annealing and softening treatment, the cutting processing performance is good.
3. Reinforced vanadium, special addition of molybdenum, excellent wear resistance.
1. The thickness is not greater than 2MM thin sheet, high efficiency falling mold, punching die and embossing die.
2. Various scissors, inlaid blades, woodworking blades.
3. Thread rolling die and wear resistant slider.
4. Cold heading mould, thermosetting resin forming die.
5. Stretch molding mold and cold extrusion die.

1, Used for making small impact load, high requirement of high wear resistance cold work die and puncher.
2, High requirement with wear resistance cold punched die, puncher, coining die, screw plate, drawing die,gauge,drill bushing, wire drawing die
For abundant stock, 15-20 days.For customized products, 30-50 days.
EF or ESR, hot rolled or forged, black surface or milling.
Hardness: annealed, HB217-269.
Cr12 / 1.2080 / D3 steel belongs to high carbon high chromium ledeburite steel, is widely used cold work die steel.
This steel has good hardenability, abrasion resistance, hot workability. Carbide distribution in the steel is good, can be used to make complex shape, heavy working conditions of all kinds of cold work mould.
Such as cold die punch, thread rolling dies, wire drawing die, die, powder metallurgy die, woodworking cutting tools, cold cutting scissors drill tool and gauge set.
It is widely used in cold making die steel, with high strength, better hardenability and good wear resistance, but the impact toughness is poor.It is mainly used for the low impact load, which requires high wear-resisting cold punching die and punch, cold cutting scissors, drill sleeve, gauge, drawing die, embossing die, thread rolling, drawing die and thread rolling mould.
