- What is D2 steel?
AISI D2 is a cold work tool steel.Cold work die steel D2 steel with high abrasion resistance, micro deformation, the wind hard tool steel, carbon content as high as 1.5%, chromium content as high as 11.5%, the heat treatment hardness can reach 60 HRC. Otai Special Steel are chinese d2 steel china supplier in steel round bar, plate, flat.
D2 tool steel properties as below:
- D2 steel composition
| Grade | C(％) | P(%) | Si(％) | S(%) | Mn(％) | Cr(%) | Mo(％) | V(%) |
| AISI D2 | 1.40～1.60 | ≤0.030 | 0.10～0.60 | ≤0.030 | 0.20～0.60 | 11.0～13.0 | 0.70～1.20 | 0.50～1.10 |

D2 tool steel heat treatment
- Forging of D2 die steel
Pre heat to 700 °C, Then rapidly heat to 900-1040 °C. Start forge the D2 steel fabrication.
- Annealing of D2 cold work tool steel
Heat to 900 °C, soak enough time. cool in furnace until to room temperature.
- Quenching of AISI D2 tool steel
For improve d2 tool steel hardness, Quenching is needs. Heat to 1010°C, heat thoroughly, cool in air.
- Tempering of Tool Steel D2
After Quenching, according different tool requirement, Tempering at different temperature. Typical data as below:
| Temperature [°C] | 150°C | 200°C | 250°C | 300°C | 350°C | 400°C |
| Hardness [HRC] | 62-61 | 61-60 | 60-59 | 57-56 | 56-55 | 56-55 |
