Typical Analysis:
C : 2.00-2.35
Si: 0.10-0.60
Mn: 0.10-0.60
P : Max 0.030
S : Max 0.030
Cr: 11.0-13.5
Similar Grades: DIN 1.2080, GB/T Cr12
Avantages:
Extremely high wear resistance.
Very high compressive strength.
Availability:
Limited.
Application:
Used in specialized applications such as draw dies, forming rolls, powder metal tooling and lamination dies.
Machinability:
Altough readily machinable in the annealed condition D3 has a lower rating than most other tool steels. It is rated at 45% of a 1% carbon tool steel. D3 has a low grindability rating.
Annealing:
D3 should be surface protected during annealing and slowly heated to 1600°to 1650°F. Hold at temperature for one hour per inch of thickness. Furnace cool to 1000°F, and then cool in still air.
