ASME SA-350 Grade LF787 Class 3 Heat Treatments
- Material shall be furnished in either the normalized and precipitation heat treated condition or in the quenched and precipitation heat treated condition.
Normalized and precipitation: Austenitize in the range from 870 to 940°C (1600 to 1725°F) for not less than 1/2 h, and remove from the furnace and cool in air. Subsequently, artificially age in the range from 540 to 650°C (1000 to 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 870 to 940°C (1600 to 1725°F) for not less than 1/2 h and quench in a suitable liquid medium by immersion; artificially age in the range from 540 to 665°C (1000 to 1225°F) for not less than 1/2 h, and cool at any convenient rate.
