SAE AS 7479B

This 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, and of 130 000 psi tensile strength at room temperature, with maximum test temperature of parts at 1200 \mDF.

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