This specification has previously been widely used and may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend this specification for future use in new designs.This specification covers the requirements for heat treated aluminum alloy die forgings, hand forgings, and ring forgings, 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 ultimately be used in the heat treated condition.
