This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of June 2007. It is recommended, therefore, that this specification not be specified for new designs. "NONCURRENT" refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. This specification covers the requirements for heat treated aluminum alloy die forgings, hand forgings, and ring forging, produced under additional mechanical property control to ensure known mechanical properties for parts used in aerospace critical applications. This specification also covers the requirements for forgings furnished in the F or 01 conditions which will be used in the heat treated condition.
