This SAE Aerospace Standard (AS) establishes the requirements for AS3504 and AS3505 thin wall self-locking inserts made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Number System as UNS N07718. Classification: tensile strength at room temperature 185 ksi minimum test temperature of parts 1025 degrees F. The method of locking the insert into parent material to resist rotation to be by means of swaging the insert knurled collar into the prebroached knurl of the parent material. Primarily for use in aircraft engines application up to approximately 1025 degrees F where an insert with a self-locking feature is required at elevated temperature, having excellent tensile strength and resistant to relaxation.
