• 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

• AISI D2 steel equivalent

1, JIS SKD11 steel

2, GB Cr12MoV steel

3, DIN.EN 1.2379 steel

4, KS STD11 cold work steel

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:
