ASTM A 727 Heat Treatments
- Heat treated by normalizing, or normalizing and tempering, or quenching and tempering.
Normalizing: Heating to 845-925°C (1550-1700°F), holding a sufficient time to attain uniform temperature throughout, and cooling in still air. The forging shall be at a temperature below 540°C (1000°F) before heating for normalizing.
Quenching: Uniformly heating the forging to 845-925°C (1550-1700°F), holding a sufficient time to attain uniform temperature throughout, and quenching into a suitable liquid medium. The forging shall be at a temperature below 540°C (1000°F) before heating for quenching.
Tempering: Reheating the forging subsequent to normalizing or quenching to at least 595°C (1100°F), but not above the lower transformation temperature, for 30 min/25 mm (30 min/in.) of maximum section thickness, with minimum holding time at tempering temperature not less than 30 min.
