Hot Rolled 1.2379 / D2 / SKD11 Long Service Life Cold Work Mould Steel Flat Bar
1.2379 / D2 is a high carbon and high chromium alloy tool steel with high hardness and wear resistance after heat treatment, and has the characteristics of strong quenching and good dimensional stability.
Equivalent grades:
| GB | DIN | AISI | JIS |
| Cr12Mo1V1 | 1.2379 | D2 | SKD11 |
Brief introduction:
1.2379 / D2 die steel, high wear resistance and micro deformation, cold working die steel, wind hard tool steel, carbon content up to 1.5%, chromium content high, noisy 11.5%, heat treatment, hardness up to 60HRC. D2 steel can be used to make large cross section, complex shape, strong impact, high resistance to cold working die steel, such as silicon steel sheet die, cold cutting scissors, trimming die, etc..
Available size(mm):

| Thickness | Width | Length | Diameter | Length |
| 8-80 | 155-610 | 3000-6000 | 14-80 | 300-6000 |
Characteristic:
1, Vacuum degassing refining treatment of steel purity.
2, The spheroidizing annealing is softened and the machining performance is good.
3, Reinforcement element vanadium, molybdenum special addition, wear resistance extremely excellent.

| Heating temperature/℃ | Cooling | Hardness/HRC | Heating temperature/℃ | Cooling | Hardness/HRC |
| 980-1040 | Oil or Air | 60-65 | 180-220 | Air | 60-64 |
| 1060-1100 | 60-65 | 510-540 | Air | 60-64 | |
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. |
