Scope

This procurement specification covers bolts and screws made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07718. Classification: a. tensile strength at room temperature 185 ksi minimum, b. maximum test temperature of parts 1200 degrees F, c. tensile strength at 1200 degrees F 145 ksi minimum, and d. stress rupture: 100 ksi stress rupture strength at 1200 degrees F. Primarily for use in aerospace propulsion systems as follows: a. for use up to approximately 1200 degrees F where elevated temperature tensile strength, stress-rupture strength, and resistance to relaxation are required, and b. for use up to approximately 800 degrees F where fatigue resistance and tensile strength are required.
