B.S. 509-690 Heat Treatments
- Austenitizing: 770-820°C;
Tempering: 540-600°C - Forgings shall be given other a double-refining or single-refining heat treatment as specified below.
Forgings of greater than 75 mm ruling section shall be quenched in oil or water at the final refining stage.
The double-refining heat treatment shall consist of:
(a) normalizing or quenching in oil or water from a temperature within the range 880°C to 920°C; followed by
(b) normalizing or quenching in oil or water from a temperature within the range 780°C to 820°C; followed by
(c) tempering at a temperature within the range 560°C to 600°C. The forgings shall be held at the tempering temperature for not less than 1h for each 25 mm of thickness and quenched in air, oil or water. The rate of cooling shall be as fast as is practicable and not less than 170 °C/h down to a temperature of 200°C.
The single-refining heat treatment shall consist of:
(1) normalizing or quenching in oil or water from a temperature within the range 780°C to 820°C; followed by
(2) tempering at a temperature within the range 560°C to 600°C. The forgings shall be held at the tempering temperature for not less than 1h for each 25 mm of thickness and quenched in air, oil or water. The rate of cooling shall be as fast as is practicable and not less than 170°C/h down to a temperature of 200°C.
Tempered at 560 to 600°C
