AS7471E - Bolts and Screws, Nickel Alloy, UNS N07001 Tensile Strength 165 ksi, Corrosion and Heat Resistant, Procurement Specification

Details
Document Number: AS7471E
Revision Number: E
Title
Bolts and Screws, Nickel Alloy, UNS N07001 Tensile Strength 165 ksi, Corrosion and Heat Resistant, Procurement Specification
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 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; and AS7471-1 165 ksi minimum ultimate tensile strength at room temperature; 99 ksi minimum ultimate shear strength at room temperature.

Primarily for aerospace propulsion system applications where a good combination of tensile strength, and resistance to relaxation at elevated temperatures up to approximately 1500 °F is required.
