D2 Tool Steel | 1.2379 | Cr12MoV | SKD11 steel

  • 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 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°C200°C250°C300°C350°C400°C
Hardness [HRC]62-6161-6060-5957-5656-5556-55

Mechanical properties and Physical properties of AISI D2 steel grade material

  • Melting point 1421°C
  • Density of D2 steel: About 7.85 kg/cm3 at room temperature
  • Hardness: Rockwell C 62 HRc, Vickers 748 V
  • Izod impact unnotched: 77 J
  • Elastic modulus: 190-210 GPa.
  • Thermal Properties: 10.4 x 10-6/ºC
