Heat treatment Related
Forged of D3 Tool steels
Slowly heated the D3 steel material to 650-680°C (1202-1256°F) before raising the temperature to 1050-1100°C (1922-2120°F) and soak D3 tool steel material until uniformly heated. Initial hammer blows should be light due to the comparatively high hot strength of this steel.
The D3 steel forged temperature should be maintained above 1000°C(1832℉) until the D3 steel metal begins to yield. Final forged should not be done below 900°C(1652℉). Slowly cool after forged is essential to avoid the possibility of cracking.
Annealing of tool steel D3
Slowly heated D3 steel to 850-870 ℃(1562-1598°F) and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace at a rate of 4°C (40°F) per hour or less.. The D3 tool steel will get MAX 250 HB (Brinell hardness).
Hardening of D3 tool steel
D3 steels should be heated uniformly to 790-820°C (1436-1508°F) until completely heated through. Then heated to the hardening temperature of 950-980°C(1742-1796℉), soak at the temperature enough time, let D3 steel to be thoroughly heated .
Then withdraw D3 steel tools from the furnace ;either air cool or oil quench.
Tempering of D3 steel tool
Tempering of D3 steels is performed at 150-400°C (302-752°F), Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Get Rockwell C hardness of 57 to 62. Others different Heat treatment temperature will get different hardness. Below only for reference.

Other types of Tool Steel Grades :-
A2 Tool Steel
A2 tool steel is an air hardening, cold work, chromium alloy die steel that is preferable to O1 tool steel in applications requiring greater size stability, machinability and safer hardening. The wear resistance properties and cost place A2 between that of O1 and D2 tool steel making it a good all purpose grade for many applications. The increased wear resistance and lower distortion make A2 tool steel particularly useful in longer production runs on either light or heavy gauge stock. Applications include: blanking dies, forming dies, trimming dies, stamping dies, coining dies, drawing dies, extrusion dies, punches, shear and slitter blades, gauges, knurling tools, rolls, mandrels and machine parts.

M42 Tool Steel
M42 tool steel is a molybdenum high speed tool steel with 8-10% cobalt added for increased hardness and hot hardness that is superior to other high speed grades. This results in a sharper cutting edge that lasts longer, even when being used to machine high-hardness and hard-to-machine alloys in heavy duty and high production applications. M42 tool steel can be heat treated to a hardness greater than any other high speed steel and achieves the highest level of red hardness making it ideal stainless steels or any other hard to machine grades. This material has been hardened to 65-67 Rc. Typical uses include milling cutters, broaches, taps, drill bits, reamers, punches, saws, knives, and thread rolling dies. Common trade names include Braemax, CPM REX M42, Cyclops M42, Dynamax, Exocut, HS-100, Hypercut, Molite M42, Super Star, VEW S500, Uddeholm 442, Vasco Hypercut.
