Heat Treatment
| HEAT TREATMENT | TEMPERATURE |
|---|---|
| Annealing | Heat uniformly in a protective atmosphere (or vacuum) to 1600°F (870°C) and soak for 2 hours. Slow cool 30°F (15°C) per hour until 1000°F (540°C). Parts can then be cooled in air or furnace as desired. Hardness expected is BHN 245 -275. |
| S tress relieving (soft) | Heat uniformly to 1100 -1300°F (595 -700°C), soak for 2 hours, and cool in air or furnace. |
