ASTM F879 Group 1-CW1 302HQ Heat Treatments
- Condition CW1 - shall be annealed by heating to 1040 +/- 10°C (1900 +/- 50°F) to obtain maximum corrosion resistance and minimum permeability. The screws shall be held for a sufficient time at temperature, then cooled at a rate sufficient to prevent precipitation of the carbide, then cold worked to develop specific properties.
