Studs, Steel, UNS S66286, Aged After Roll Threaded, Procurement Specification For AS7481

This procurement specification covers studs made from a corrosion and heat resistant age hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286 and of 130 ksi tensile strength at room temperature, with maximum test temperature of parts at 1200 degrees F.

Primarily for aerospace propulsion system applications where the coefficient of expansion of the stud is more compatible in light alloys, and where stress-rupture and creep resistance are of primary importance at elevated temperatures.
