Product Code:SAE AS7477
Title:Bolts and Screws, Steel, UNS S66286 Tensile Strength 130 ksi, Procurement Specification
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This document covers bolts and screws made from a corrosion and heat resistant precipitation hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286. The following specification designations and their properties are covered: AS7477: 130 ksi minimum ultimate tensile strength at room temperature 70 ksi stress-rupture strength at 1200 degrees F; and AS7477-1 130 ksi minimum ultimate tensile strength at room temperature 85 ksi minimum ultimate shear strength at room temperature. Primarily for aerospace propulsion system applications where a good combination of fatigue resistance, tensile strength, and resistance to relaxation at elevated temperatures is required.
