| eatment | Temperature Range | Cooling/Quenching | Notes |
| Forging | 2000-2100° F | Slow. | Heat slowly and uniformly. Do not forge below 1700°F. Cool in vermiculite or other insulating media. |
| Annealing | 1545-1600° F | Cool slowly at a rate of 25° F per hour to 1000° F. | Protect against surface decarburization using controlled atmosre or by pack-annealing. |
| Stress Relieving | 1020-1200° F | Cool slowly in furnace to 930° F. Then in air. | Stress relieve after rough machining |
| Preheating | 1450-1500° F | ? | Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible |
| Hardening | 1800-1900° F | In air. | Temper immediately after hardening. Allow to cool to 125-150° F before tempering. Soak time is 15 minutes per inch of thickness. Minimum of 30 minutes. |
| Tempering | ? | ? | Complete equalization of temperature throughout the tool is essential for good results. Double temper. Recommended temperature is 400-1000° F |
