D2 / SKD11 / 1.2379 Hot Rolled Alloy Steel Round Bar of Cold Work Tool Steel
D2 is a kind of high-carbon and high-chromium alloy tool steel, after heat treatment has a high hardness of grinding, and has strong hardenability, good dimensional stability characteristics, suitable for making high-precision long-life cold mold and thermoforming plastic mold.
Other application suitable for this tool steel include deep drawing dies, cupping dies, forming die sheet metal forming rolls, shear blades for strip and sheet including flying shears, circular cutters for cold rolled strip, trimmer dies, thread rolling dies, cold extrusion dies, broaches, plug gauges, ring gauges, master hobs for cold hobbing plastic moulds, cut moulds for plastics, special taps, straybolt taps, brick and tile mould liners.

| Feature | |||||||
| 1,Good processing, heat treatment size stability. 2,Excellent machinability. 3,Excellent dimensional stability when hardened. 4,After hardening and tempering, the high surface hardness match well with the toughness of the body. |

| Applications | |||||||
| For metal stamping die, drawing die, stainless steel sheet punching die, high hardness punching die, cutting knife mold, Roll Die, metal parts production, machinery manufacturing etc. (1) Used for drawing die of refrigerator compressor rear cover, quenching hardness 56~58HRC. (2) In order to improve the service life of flat rolling material for D2 cold working die, the wear resistance and impact toughness of steel are greatly improved by adding rare earth, so as to improve the service life of flat rolling material of round die. (3) Because the content of V and Mo in D2 steel is higher than that of Cr12MoV steel, it has better comprehensive properties, and the traditional Cr12MoV steel will be replaced gradually. (4) Made of D2 steel rolling wheels, from Taiwan palette die, and Cr12MoV can improve the service life of steel compared to 5 ~6 times. |
