Bolts and Screws, Steel, UNS S66286 Tensile Strength 130 ksi, Procurement Specification
|Publication Date:||1 August 2020|
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 °F
AS7477-1: Inactive for design
AS7477-2: 130 ksi minimum ultimate tensile strength at room temperature
78 ksi minimum ultimate shear strength at room temperature
130 ksi minimum tensile strength at room temperature.
1200 °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.
