    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.

    We usually hold D2 tool  steel on sale activities, and you would have our price on regular  schedule. Contact us and sign in our newsletter to have D2 tool steel  materials price list and commercial quote today.

  • Ever wondered how ball bearings are made?
    Today on How It’s Made, ball bearings, electrical wires, wax casting and automated machines. With the entire high end couplet these days, the lowly ball bearing gets forgotten but many machines needs ball bearings to rotate. Household appliances, industrial machines and car engine parts, alternator and fans. This is what’s called a deep groove radio ball bearing. It has steel balls that move inside tracks called raceways. The raceways are carved into a set of heavy-duty rings. The balls were made from the same type of steel. They first prepare the shape of the rings to the right thickness. They insert the inner ring to the outer ring. The set passes through a grinder that alters width to the correct thickness. A gauge checks the width of each ring as it exit.

    Now they separate the inner and the outer rings in order to grind their outer circumference on separate machines. The outer rings enter the grinder which shapes its outer surface to a precise roundness and diameter. A water-based liquid keeps the outer rings from overheating which would cause warping. The ring exits the grinder from a gauge that checks the diameter. Next the outer rings go for grinding. A brace of steel wheels and oil cog shapes the surface to a precisely correct roundness and size. The inner ring and raceways goes through a similar machine. Now the ring goes for polishing and a brace of stone lubricates with oil polishes the steel until you see a reflection. Next stop is washing. They coat the rings with thick oil and a fine stone grid. They clean the raceways with kerosene. Elsewhere in the planet they classify the steel balls according to size.

    These balls started out as steel wire. Machine cuts them into pieces and a then punches them into steel balls. Those rough balls go into the grinder which removes the bumps then other machine round them up and give them a mirror finish. This entire process takes a few days. The balls go through a furnace where they are hardened. Then they get a bath and cleaning solvent. After several quality checks, the finished balls goes into hoppers. The hoppers load them into an automatic assembly machine. The ball fitter sends the balls through tubes to a ball pusher that fix the correct quantity of balls into the raceways of the now re-assembled inner and outer rings. Next comes the ball cage, a metal cage that retains the balls in position around the raceways.

    The first machine installs half of the cage. The half drives holes. The next machine carefully positions the outer half of the cage. The half with rivets. The machine test spins the bearings then rivets the two halves the ball cage together. The bearing is now fully assembled. Now it goes to a solvent bath then to a series of automated quality control tests. This noise vibration tests makes sure the ball bearing operates quietly. Some types of bearings are lubricated with grease. A machine squirts evenly into the ball bearings then inserts a rubber seal after the grease. A final quality control test, an automated scale tosses out bumped bearings that aren’t the required weight. The good ones move to the laser which marks them with information such as the part number and the trademark.
