PROPRIETARY ATI AL-6XN Heat Treatments

Flat rolled products are annealed at temperatures above 1110°C (2025°F) and are then rapidly cooled to produce a fully austenitic microstructure . Since the cold formability of AL-6XN alloy is excellent, subsequent heat treatment is generally not required to maintain ductility and toughness. Hot-for med products generally must be heat treated above 1110°C (2025°F) followed by a rapid cool to dissolve any secondary phases that may have precipitated during the process. If the cooling after heat treatment is too slow, the corrosion resistance of the AL-6XN alloy will be markedly decreased. Furnace cooling of AL-6XN alloy should be avoided.

Caution: To avoid the risk of incipient melting, AL-6XN alloy should never be heated above 1290°C (2350°F).
