Bolts and Screws, Steel, UNS S66286 Classification: 130 ksi/1200 °F 1800 °F Solution Heat Treated, Aged After Roll Threaded Procurement Specification For
- Aerospace Standard
This procurement specification covers bolts and screws made from a corrosion and heat resistant age 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: AS7478: 130 ksi minimum ultimate tensile strength at room temperature 65 ksi stress-rupture strength at 1200 degrees F; AS7478-2 130 ksi minimum ultimate tensile strength at room temperature 78 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 stress-rupture strength and creep resistance are required at elevated temperature.
