SAE 52100 Heat Treatments
- Annealing temperature: 777°C (1430°F) for 20 minutes, cool to 743°C (1370°F) at a rate not faster than 29°C (52°F) per hour, cool to 716°C (1320°F) at a rate not to exceed 24°C (43°F) per hour, cool to 677°C (1250°F) at a rate not faster than 29°C (52°F) per hour, and air cool to ambient temperature.
Normalizing temperature: 885 - 913°C (1625 - 1675°F)
Austenitizing temperature: 829 - 843°C (1525 - 1550°F). Permissible austenitizing temperature of 816°C (1500°F) for parts made from 52100 requiring distortion control. Parts shall be hardened from the spherodize annealed condition or the normalized condition.
Hardening quenchant: oil, polymer. Immediately after quenching sub-zero cool parts made from 52100 at -68°C (-90°F) or lower, hold 1 hour minimum, and air warm to room temperature. For parts made from 52100 with a geometry that is susceptable to cracking during sub-zero cooling, a snap temper before sub-zero cooling is allowed. (Marquenching in a nitrate/nitrite salt bath, oil bath, or alternate quenchant operated at a set temperature applicable to the alloys processed is permitted. The parts shall be in the marquenching bath only for sufficient time to stabilize the parts at the bath temperature, but not less than 2 minutes, followed by cooling to approximately ambient temperature. Salt residues shall be removed by a hot water rinse before air tempering).
Tempering: 171 - 232°C (340 - 450°F), at least two tempering operations are required. - Bars, forgings, and tubing shall have given mechanical properties after being heated to 829 ± 6°C (1525 ± 10°F), held at heat for 20 ± 2 minutes, and quenched in commercial paraffin oil (90 - 110 SUS at 38°C (100°F)) at room temperature.
