Product Description
D2 tool steel China Supplier and stockholders, Otai Special steel is Supplier of D2 steel in round bar, flat, plate, block and sheet.
AISI D2 is a high carbon-high chromium alloy tool steel that offers great wear and abrasion resistance, due to the large volumes of carbides in its microstructure. It is widely used in long production cold work applications requiring very high wear resistance and high compression strength. D2 tool steel is machinable in its annealed condition, and like other air hardening tool steels, shows minimal distortion when treated with heat. D2 Tool Steel is available in rounds, flats, and squares, as well as ground flat stock and drill rod.

D2 cold work Tool steel Applications
D2 tool steels used for cutting, shaping and pruning is dead, gauge, longitudinal cutting knife, wearing parts, the texture is dead, thread rolling, drawing die, the rotary die cutter, knurling, bending modulus, gauge, the shear blade, polishing tools, volume, machine parts and control parts, injection screw and prompt components, sewing, extrusion die, tire shredder, etc.
D2 cold work steel Forged
Slowly heat the D2 tool steel to 700°C (1292°F) uniformly. Then heat to 900-1040°C (1652-1904°F) more rapidly. After forging slowly cool down in furnace.
D2 Tool steel Annealing
Cold work D2 steel delivery condition is annealed and machineable. For annealing, First slowly and uniformly heat D2 component to 900°C(1652°F). and Soak for 3 to 4 hours. then cool in the heat treatment furnace to room temperature.
D2 Tool steel Stress Relieving
When D2 steel material is heavily machined, ground machined or otherwise subjected to cold work, Internal pressure relief Suggestions before hardening to reduce the possibility of distortion. the stress relieving is must. For stress relieve, heat the D2 steel component to 600-650°C(1112-1202°F). Confirm soak uniformly, then cool it in the heat treatment furnace or Cool in air.
Tempering of Tool steel D2
Double tempering is recommended for Cold work D2 tool steel. It will get better Mechanical properties. Tempering of the D2 preferably is after Hardening , when the steel tools are still hand warm(about 40°C). Choose a suitable tempering temperature, Slowly and uniformly Heat the D2 tool steel Component, Until the D2 component has reached the desired temperature, soak 1 hours at least. For make the second tempering, It should be a repetition of the first.
Temperature [°C] | 150 | 200 | 250 | 300 | 350 | 400 |
Hardness [HRc] | 62-61 | 61-60 | 60-59 | 57-56 | 56-55 | 56-55 |
D2 Tool steel Quenching
