ASTM A 350 Grade LF787 Class 3 Heat Treatments
- Normalized and precipitation heat treated: Austenitize in the range from 871 - 940°C (1600 - 1725°F) for not less than 1/2 h, remove from the furnace and cool in air. Subsequently, artificially age in the range from 538 - 649°C (1000 - 1200°F) for not less than 1/2 h, and cool at any convenient rate.
Quenched and precipitation heat treated: Austenitize in the range from 871 - 941°C (1600 - 1725°F) for not less than 1/2 h and quench in a suitable liquid medium by immersion; artificially age in the range from 538 - 663°C (1000 - 1225°F) for not less than 1/2 h, and cool at any convenient rate.
