Product Description
D2 Tool Steel
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.

AISI D2 Form of Supply
D2 tool steel, we can supply the round bar, flat bar,
plate and square block. Diameters can be sawn to your required
lengths as one offs or multiple cut pieces. Rectangular pieces can
be sawn from flat bar or plate to your specific sizes. Ground tool
steel bar can be supplied, providing a quality precision finished
bar to tight tolerances.

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 **0°C
(***2°F) uniformly. Then heat to *******0°C
(********4°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 **0°C(***2°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
******0°C(********2°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 *0°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.
