Specifikacije

AISI D3 alloy steel is heat treatable and will offer a hardness in the range 58-64 HRC. After heat treatment D3 tool steel is hard, durable and dense, and is immune from sinking in use. It offers a measure of corrosion resistance when polished. In general, the applications of AISI D3 tool steel resemble those of D2 tool steel but it should be remembered that alloy tool steel D3 has better wear resistance of the two steels and is preferred for such items as shear blades. Owing to its higher wear resistance, AISI / ASTM D3 cold work steel is slightly more difficult to grind than D2 steels.


Aplikacije:

D3 tool steel used for cold work tool products. Like forming dies , thread rolling dies, cutting knife, etc.
