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.
