D2 Round Bars / 1.2379 Round Bars

1.2379 Round Bars / D2 Round Bars is a High Carbon High Chromium Tool Steel, heat treatable to 60-62 HRC. D2 offers excellent wear and abrasion resistance, due to large volumes of carbides in the micro-structure. D2 steel 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 steel is available in de-carb free rounds, flats, and squares, as well as ground flat stock and drill rod.

D2 / 1.2379 is a ledeburitic cold work tool steel with high wear resistance and good cutting strength. A high resistance to abrasive and adhesive wear and high pressure resistance are given. Due to the good mechanical properties, this steel can be used in many different applications. Due to the secondary hardening properties a supplementary nitriding and coating of the surface is easily possible.

D2 / 1.2379 Round Bar is ideally suited for the manufacture of tools that require high abrasion resistance and shape stability during hardening. It is used for making punches, cutters, draughts, reamers, anvils for forging scythes, tools for cutting horns, marble, milling cutters, retractors, rollers, jaws for cold rolling of threads, knives for the production of nails, cutting boards for blanking dies of various shapes, tools for cutting paper and plastics, cold working dies, deburring machines, drawing dies, and gauges. Welding is hard and should be considered only as a mean to repair a damaged tool.

Heat Treatment :

• Soft annealing: The material 1.2379 can be annealed at temperatures of 830°C - 850°C. Subsequently, a slow cooling in the oven must be done.
• Stress relief annealing: Stress relief annealing is carried out at 650°C - 700°C with subsequent cooling of the furnace.
• Hardening: Hardening takes place at 1010°C - 1030°C with a final cooling in oil, warm bath, air or vacuum.
• Tempering: Tempering takes place at 170°C - 190°C.
