D2 tool steel is an air-hardening, high carbon, high chromium tool steel with extremely high wear resisting properties. It is a very deep hardening steel and will be practically free from size change after proper treatment. The high percentage of chromium gives it mild corrosion-resisting properties in the hardened condition. It has low machinability and grindability, with a medium resistance to decarburization. D2 is commonly used in long production, cold work applications, high wear applications and it is very popular as a knife blade steel.

D2 tool steel is also available in precision milled Super Square, which can be 2, 4, or 6 side precision milled. Our Super Square is milled to customer tolerances and delivered quickly for your convenience. Alro Steel is also able to grind tool steel with a rotary grinding machine for a fast turnaround, with reciprocal grinding for an even smoother finish. 

Main applications are stamping tools, punches and dies, forming dies, shear blades and cutters, ceramic molds,

5. 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.

6. D2 Tool Steel Material Application
Blanking Dies, Forming Dies, Coining Dies, Slitting Cutters, Heading Tools, Long Punches, Forming Rolls, Edging Rolls, Master Tools, Beading Rolls, Intricate Punches, Extrusion Dies, Drawing Dies, Lamination Dies, Thread Rolling Dies, Shear Blades, Burnishing Tools, Gauges, Knurls, Wear Parts.
