PROPRIETARY Whitebear Heat Treatments

Hardening:Preheating: To minimize distortion and stresses in large or complex tools use a double preheat. Heat at a rate not exceeding 222°C per hour (400°F per hour) to 621-677°C (1150-1250°F) equalize, then heat to 816-843°C (1500-1550°F). For normal tools, use only the second temperature range as a single preheating treatment.
Austenitizing (High Heat): Heat rapidly from the preheat to: 1038-1093°C (1900-2000°F). Equalize and soak at the austenitizing temperature for 30 minutes for pieces up to 25.4 mm in thickness, plus 15 minutes for each additional 25.4 mm of thickness. For maximum toughness, austenitize at the low end of the recommended range. For maximum wear resistance, austenitize at the upper end of the recommended range.
Quenching: Air or pressurized gas to 66-51°C (150-125°F).
Tempering: Temper immediately after quenching. Hold at temperature for 1 hour per 25.4 mm of thickness, 2 hours minimum, then air cool to ambient temperature. Typical tempering temperatures are 510 to 593°C (950 to 1100°F). Double tempering is required.
Cryogenic Treatment: Refrigeration treatments should typically be performed after the first 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 222°C per hour (400°F per hour) to 843-899°C (1550-1650°F), and hold at temperature for 1 hour per 25.4mm of maximum thickness; 2 hours minimum. Then cool slowly with the furnace at a rate not exceeding 11°C per hour (25°F per hour) to 538°C (1000°F). Continue cooling to ambient temperature in the furnace or in air.
