D3 Tool Steel
D3 steel also knows as 1.2080, is an air-hardening, high-carbon, high-chromium tool steel. It displays excellent abrasion/wear resistance and has good dimensional stability and high compressive strength.
It is heat treatable and will offer a hardness in the range of 58-64 HRC. Due to its abrasion resistance in the hardened condition, D3 machining should be limited to finished grinding.
In General, Application of D3 material is same as of D2 but it should be remembered that D3 has better wear resistance of the two steels and is preferred for such items as shear blades.

Ground Flat Stock
Precision ground flat stock / gauge plate can be produced using D3 tool steel. Subject to size suitability and availability pieces can be produced in approximately 2 to 3 weeks. Standard and non-standard sizes are available.
Forging
Pre-heat at 900-950°C then raise temperature to 1050-1100°C. Soak until uniformly heated. D3 tool steel is relatively hard at elevated temperature. Therefore, initial hammer blows must be light and the temperature must not be allowed to fall below 1020°C until the metal begins to flow. Final forging should not be done below 900°C.
Annealing
Annealing of D3 tool steel needs to be done in a controlled atmosphere furnace. D3 tool steels should be heated thoroughly to 871°C (1600°F) and cooled slowly at a rate of not more than -6°C (20°F) per hour, until the furnace is black. Then the material should be removed and air cooled.
Stress Relieving
Heat to 650-700ºC. Soak for 2-4 hours then furnace cool.
Hardening
D3 tool steel should be heated properly since it is very sensitive to overheating and if not heated maximum hardness cannot be achieved. The work should be directly placed in a furnace preheated to 954°C (1750°F) and soaked for 20-25 minutes, plus 5 minutes per inch of thickness, and then oil-quenched to harden it.
