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

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.
