    4. 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℃). After D2
    die steel forging, cool slowly in lime, mica, dry ashes or furnace. AISI D2 steel
    should always be annealed after forging.

    5. D2 Tool Steel Heat Treatment

    • Heat Treatment

    ASTM  D2 steels alloy should be preheated very slowly to 815oC (1500oF) and  then temperature can be increased to 1010oC (1850oF). They are then held  at 1010oC (1850oF) for 20 to 45 minutes and air cooled (air quenched).

    • Annealing

    Annealing  of D2 tool steels material should be done at 871 to 898oC (1600 to  1650oF) followed by slow furnace cooling at 4.4oC (40oF) per hour or  less.after which cooling rate may be increased. Suitable precautions  must be taken to prevent excessive carburization or decarburization.

    • Stress Relieving

    When  desirable to relieve the strains of machining, heat D2 grade steel  slowly to 1050°-1250°F, allow to equalize, and then cool in still air  (Strain Relieving).

    • Preheat Prior To Hardening

    Preheat slowly to 1350°-1450°F and hold at this temperature until grade steel D2 material is uniformly heated.

    • Hardening

    After  thorough preheating, heat to 1800°-1850°F. Hold the work piece at the  hardening temperature until it is completely and uniformly heated.

    • Quenching

    AISI  D2 steel tool material is an air hardening steel and will develop  hardness on cooling in still air. To avoid scaling and prevent  decarburization of the work piece surface, controlled atmosphere or  vacuum furnaces are recommended. If these furnaces are not available,  pack hardening, salt baths or wrapping the piece in stainless steel foil  will provide some degree of surface protection in the hardening  process. Parts should be allowed to cool to 150F, or to where they can  be held in the bare hand, and then temper immediately.

    • Tempering

    The  tempering temperature on material D2 steel may be varied according to  the desired hardness. D2 steels can be tempered at 204oC (400oF) for  achieving Rockwell C hardness of 61 and at 537oC (1000oF) for a Rockwell  C hardness of 54.

    6. D2 Tool Steel Material Application
     AISI grade D2 tool steels are used for long run tooling applications,  where wear resistance is important, such as blanking or forming dies and  thread rolling dies.

    Some main applications for D2 tool steel are as below:

    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.
