D2 cold work steel -What is the D2 tool steel’s mechanical properties?

With over 20 years’ pre-sales and after-sales special steel, Otai helps distributors and end-users to avoid all possible swindle and cheat. Our steel materials meet DIN / ASTM / EN / JIS etc different international standards. D2 tool steel, we can supply the round bar, flat bar, plate, and square block.

D2 is a high carbon-high chromium alloy tool steel that offers great wear and abrasion resistance, due to the large volumes of carbides in its microstructure.

It is widely used in long production cold work applications requiring very high wear resistance and high compression strength. D2 tool steel is machinable in its annealed condition, and like other air-hardening tool steels, shows minimal distortion when treated with heat. D2 Tool Steel is available in rounds, flats, and squares, as well as ground flat stock and drill rod.

D2 cold work steel used for cutting, shaping and pruning is dead, gauge, longitudinal cutting knife, wearing parts, the texture is dead, thread rolling, drawing die, the rotary die cutter, knurling, bending modulus, gauge, the shear blade, polishing tools, volume, machine parts and control parts, injection screw and prompt components, sewing, extrusion die, tire shredder, etc.
