PROPRIETARY WM L-6 Heat Treatments

  • Forging: Heating for forging must be done slowly and uniformly. Soak through at 1800-1900°F, and reheat as often as necessary, stopping work when the temperature drops below 1600°F. After forging cool slowly in lime, mica, dry ashes or furnace. Should always be annealed after forging.
    Annealing:Heat slowly to 1400-1450°F, hold until the entire mass is heated through, and cool slowly in the furnace (40°F per hour) to about 1000°F, after which the cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
    Strain relieving:When desirable to relieve the strains of machining, heat slowly to 1050-1250°F, allow to equalize, and then cool in still air.
    Preheat for hardening:Warm slightly before charging into the preheat furnace, which should be operating at about 1100-1200°F.
    Hardening:If preheating is not employed, it is good practice to warm the parts on top of the furnace, or in front of the door, before charging into the furnace. The hardening temperature should be 1500-1550°F, depending on the section size.
    Quenching:WM L-6 should be quenched into warm circulating oil. It should be allowed to cool until it has reached a temperature of 125-150°F, or to where it can be held in the bare hand, and tempered immediately.
    Tempering:This grade of steel is generally tempered in the range of 300-900°F.
