Bolts and Screws, Steel, Uns S66286 Tensile Strength 130 Ksi, Procurement Specification AS7477

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: inactive for design; AS7477-2: 130 ksi minimum ultimate tensile strength at room temperature 85 ksi minimum ultimate shear strength at room temperature. Classification: 130 ksi minimum tensile strength at room temperature 1200 degrees F maximum test temperature of parts.

Primarily for aerospace propulsion system applications where a good combination of fatigue resistance, tensile strength, shear strength, and resistance to relaxation at elevated temperatures is required.
