Heat treat
- Preheat
- 1,500-1,550°F, equalize.
- Austenitize
- Heat rapidly from preheat. For optimum wear resistance, soak for 5 to 15 minutes 2,150°F. For balance of wear resistance and toughness, soak for 15 to 30 minute 2,050°F. For maximum toughness and minimum distortion in cooling, soak for 30 to 60 minutes 1,975°F.
- Quench
- Plate, air or medium oil quench to 125°F.
- Temper
- Temper immediately after quenching. Typical temperature range is 1,000-1100°F. Do not temper below 1,000°F. Hold at temperature for two hours then air cool to ambient temperature. Double tempering is required. Triple tempering is required when austenitized at 2,100°F or higher.
