Product Code:SAE AMS2248
Title:Chemical Check Analysis Limits, Corrosion and Heat-Resistant Steels and Alloys, Maraging and Other Highly-Alloyed Steels, and Iron Alloys
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:Product Code:SAE AS7471
Title:Bolts and Screws, Nickel Alloy, UNS N07001 Tensile Strength 165 ksi, Corrosion and Heat Resistant, 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 N07001. The following specification designations and their properties are covered:AS7471165 ksi minimum ultimate tensile strength at room temperature. 75 ksi stress-rupture strength at 1350 掳F.AS7471-1165 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 掳F is required.
