We are professional AISI D2 D-2(SKD11,SKD-11,BD2,SAE J437,SAE J438)strip Sheets shearing machine shear blade Cutting Blades flying shears circular cutters factory from china
D2 is a high carbon - high chromium air hardening tool steel, heat treatable to 60-62 Rc. D2 offers excellent wear and abrasion resistance, due to large volumes of carbides in the microstructure. D2 is widely used in long production cold work applications requiring very high wear resistance and high compression strength. It is machinable in the annealed condition, and, like other air hardening tool steels, exhibits minimal distortion in heat treat. D2 is available in de-carb free rounds, flats, and squares, as well as ground flat stock and drill rod.

A.I.S.I. D2 conforms to ASTM A681, DIN 1.2379, SAE J437, J438
Typical applications for D2 tool steel are blanking, forming, and trim dies, gages, slitting cutters, wear parts, lamination dies, thread rolling dies, drawing dies, rotary cutting dies, knurls, bending dies, gages, shear blades, burnishing tools, rolls, machine parts, master parts, injection screw and tip components, seaming rolls, extrusion dies, tire shredders, scrap choppers, etc.
FORGING
Heating for forging must 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. After forging, cool slowly in lime, mica, dry ashes or furnace. D2 should always be annealed after forging.
ANNEALING
Heat slowly to 1550°-1600°F, hold until entire mass is heated through, and cool slowly in the furnace (40°F per hour) to about 1000°F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
