This procurement specification covers bolts and screws made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07001. The following specification designations and their properties are covered:
AS7471 165 ksi minimum ultimate tensile strength at room temperature.
75 ksi stress-rupture strength at 1350 °F.
AS7471-1 165 ksi minimum ultimate tensile strength at room temperature.
99 ksi minimum ultimate shear strength at room temperature.
Primarily for aerospace propulsion systems applications where a good combination of tensile strength, and resistance to relaxation at elevated temperatures up to approximately 1500 °F is required.
