Type 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 ??c. Tensile strength at 1200 ??145 ksi minimum d. Stress Rupture: 100 ksi stress rupture strength at 1200 ??Application Primarily for use in aerospace propulsion systems as follows: a. For use up to approximately 1200 ??where elevated temperature tensile strength@ stress-rupture strength@ and resistance to relaxation are required. b. For use up to approximately 800 ??where fatigue resistance and tensile strength are required. Safety-Hazardous Materials While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
