(R) Bolts and Screws, Nickel Alloy, UNS N07718 Tensile Strength 185 ksi Stress Rupture Rated Procurement Specification
|Publication Date:||1 April 2021|
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 N07718. The following specification designations and their properties are covered:
AS7467 185 ksi minimum ultimate tensile strength at room temperature
145 ksi minimum ultimate tensile strength at 1200 °F
100 ksi stress rupture strength at 1200 °F
AS7467-1 185 ksi minimum ultimate tensile strength at room temperature
111 ksi minimum ultimate shear strength at room temperature
Primarily for aerospace propulsion systems bolt applications where a good combination of tensile strength, stress rupture strength, and resistance to relaxation is required for use up to approximately 1200 °F; also, where a good combination of tensile strength and shear strength is required.
