PROPRIETARY WM O-6 热处理

• Preheating: Heat at a rate not exceeding 400°F (222°C) per hour to 1200-1250°F (649-677°C) and equalize.
  Austenitizing (high heat): Heat slowly from the preheat to 1450-1550°F (788-816°C); Less than ½ inch thickness: use 1450°F (788°C); ½ to 2 inches (12.7 - 50.8 mm) thickness: use 1475°F (802°C); Over 2 inches (50.8 mm) thickness: use 1500°F (816°C).
  Quenching:Oil or pressurized gas. For oil, quench to 150-125°F (66-52°C). For pressurized gas, the quench rate to below 1000°F (538°C) should be a minimum of 400°F (204°C) per minute, and is critical for obtaining the desired properties.
  Tempering:Temper immediately after quenching. The typical tempering range is 300-400°F (149-204°C). Hold at temperature for 1 hour per inch of thickness, 2 hours minimum, then air cool to ambient temperature. The actual hardness obtained is dependent upon the section size of the part being quenched and tempered. To minimize internal stresses in cross sections greater than 3 inches (76.2 mm) and to improve stability in parts that will be EDM’d after heat treatment, a soaking time of 4-6 hours at the tempering temperature is strongly recommended.
  Cryogenic Treatment: Refrigeration treatments should typically be performed after the temper, and must be followed by a second temper.
  Annealing: Annealing must be performed after hot working and before rehardening. Heat at a rate not exceeding 400°F (204°C) per hour to 1450°F (788°C), and hold at temperature for 1 hour per inch (25.4 mm) of maximum thickness, 2 hours minimum. Then cool at 10°F (-12°C) per hour to 1300°F (704°C). Then cool at 25°F (-4°C) per hour from 1300°F (704°C) to 1000°F (538°C). Then cool in air to ambient temperature. The resultant hardness should be a maximum of 229 HBW.
