PROPRIETARY UGI 4545 AIR Heat Treatments
- Forging: reheating must be carried out at a temperature between 1150°C and 1200°C, forging between 1200°C and 950°C. Cooling after forging must be performed in air or oil.
Heat treatments are composed of two steps: austenitisation and aging.
Austenitisation:solution annealing is performed around 1030°C - 1050°C, and is interrupted by oil quenching or alternatively by air cooling for small section parts. Stress relief treatment at 300°C for 1 hour after austenitisation is recommended.
Aging: performed after solution treatment. Aging treatments can be performed between 480°C (condition H900) and 620°C (condition H1150). The condition H900 corresponds to the peak of hardening, for which the Cu precipitates induce a maximum of hardness.The condition H1025 is often chosen by customers because it leads to an optimal trade-off between strength and toughness.
Softening: the lowest strength or hardness is obtained after the thermal cycle H1150M, consisting into of a solution annealing followed by a tempering at 760°C for 2 hours and an aging at 620°C for 4 hours.
