    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.

  • ASTM A213 T22 Seamless Ferritic and Austenitic Alloy-Metal Boiler, Superheater, Warmth-Exchanger Tubes.
    Grades made up of the letter H in their designation have requirements distinctive from these of identical grades not made up of the letter H.
    These distinctive requirements provide greater creep-rupture power than commonly achievable in identical grades without having these distinctive requirements. ASTM A213 T22 tubes shall be made by the seamless approach and shall be either very hot concluded or cold concluded, as specified. Quality TP347HFG shall be cold concluded. Warmth procedure shall be finished independently and in addition to heating for very hot forming. The ferritic alloy and ferritic stainless steels shall be reheated. On the other hand, austenitic stainless metal tubes shall be furnished in the heat-taken care of condition. Alternatively, straight away soon after very hot forming, whilst the temperature of the tubes is not a lot less than the bare minimum option temperature, tubes may possibly be separately quenched in water or fast cooled by other usually means. Stress examination, hardness examination, flattening examination, and flaring examination shall be finished to just about every tube. Also, just about every tube shall be subjected to the nondestructive electric examination or hydrostatic examination.
    ASTM A209 Through A213
    Other conventional specifications incorporate the types of A209 seamless carbon-molybdenum alloy-metal boiler and superheater tubes A210 seamless medium-carbon metal boiler and superheater tubes and A213 seamless ferritic and austenitic metal boiler, superheater and heat-exchanger tubes.
    Piping wall thicknesses array from 1/2 inch to five inches. A213 grades also have the letter H or M assigned, which improvements the composition and specifications for that series.
    This summary is a short summary of the referenced conventional. It is informational only and not an formal portion of the conventional the comprehensive text of the conventional alone should be referred to for its use and application.
    ASTM does not give any guarantee express or implied or make any illustration that the contents of this summary are accurate, finish or up to date.
    Wall thickness is average wall or according to ASME SA530.
    Notes for Bend Examination:
    For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7. or a lot less shall be subjected to the bend examination as a substitute of the flattening examination.
    Other pipe whose diameter equals or exceeds NPS 10 may possibly be specified the bend examination in location of the flattening examination subject matter to the acceptance of the purchaser.
    The bend examination specimens shall be bent at place temperature via one hundred eighty without having cracking on the outdoors of the bent part.
    Packing:
    Packed in wooden crates, wrapped in plastic, and suitably secured for sea-worthly shipping and delivery or as asked for.
    Both of those ends of just about every crate will suggest the order no., heat no., dimensions, fat and bundles or as asked for.
    Shipping and delivery:
    Pipes are supplied in hexagonal bundles or spherical bundles tied with metal strip.
    Excess weight of bundle – up to 5000 kg on ask for of client.
    Just about every bundle is furnished with 3 tags.
