D2 Tool Steel Bar For Knife

D2 Die steel is used to make cold die, hot forging die, die casting die and other steel types. Moulds are the main processing tools for manufacturing parts in machinery manufacturing, radio instruments, motors, electrical appliances and other industrial sectors. The quality of the mold directly affects the quality of the pressure processing process, the accuracy of the product, and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to the reasonable structure design and processing accuracy.

D2 Tool  Steel Specifications :

D2 Tool Steel Material Characteristics

Good mechanical property and quenching, make surface have equal hardness after deal with it.

Nice polishing and low roughness.
Normally make the heat-treatment to harden condition before used, it can be used directly after the mould machined.

D2 Tool steel forfing process

AISI/ASTM A681 D2 Grade Steel Forging   

Heating for forging of AISI D2 tool steel should be done slowly and uniformly. Soak through at 1850°-1950°F and reheat as often
as necessary, stopping work when the temperature drops below 1700°F(926°C).

After D2 die steel forging, cool slowly in lime, mica, dry ashes or furnace.

AISI D2 steel should always be annealed after forging.
