D2 Tool Steel Round

D2 tool steel is an air-hardening, cold work, high carbon, high chrome tool steel with exceptionally high wear resistance properties. D2 tool steel properties combine minimal distortion in heat treatment, high toughness and wear resistance at the expense of grindability and machinability compared to other grades. Its deep hardening ability helps it to resist chipping and cracking. These characteristics along with price make D2 tool steel a high performance choice for applications requiring maximum dimensional stability in heat treatment, toughess, and wear resistance for longer life in long run, high production die applications. These applications include knife blades, thread rolling dies, lamination dies, blanking dies, forming dies, trimming dies, stamping dies, coining dies, drawing dies, extrusion dies, punches, punch plates, shear and slitter blades, gauges, knurling tools, rolls, mandrels and machine parts. Common trade names include Ontario, Aristocrat, Superior No 3, High-Chrome, Olympic FM, Airdi 150, Ohio Die, Ultra Die 3, CCM, AL3, CNS-1, Atmodie, 610, FNS. D2 plates and flats are supplied in a decarb free and annealed condition.
