Product Code:SAE AS7467
Title:Bolts and Screws, Nickel Alloy, UNS N07718 Tensile Strength 185 ksi Stress Rupture Rated Procurement Specification
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: 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.Tthe 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掳F, 100 ksi stress rupture strength at 1200掳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 system applications where a good combination of tensile strength, stress-rupture strength, and resistance to relaxation is required for use up to approximately 1200掳 F; also, where a good combination of tensile strength, and shear strength is required.
