Bolts and Screws, Nickel Alloy, UNS N07718 Tensile Strength 185 ksi Stress Rupture Rated Procurement Specification
|Publication Date:||1 June 1997|
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. The following specification designations and their properties are covered:
AS7467 185 ksi minimum ultimate tensile strength at room temperature
145 ksi minimum ultimate tensile strength at 1200 °F
100 ksi stress rupture strength at 1200 °F
AS7467-1 185 ksi minimum ultimate tensile strength at room temperature
111 ksi minimum ultimate shear strength at room temperature
Primarily for aerospace propulsion systems applications where a good combination of tensile strength, stress rupture strength, and resistance to relaxation is required for use up to approximately 1200 °F; also, where a good combination of tensile strength, and shear strength is 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 take necessary precautionary measures to ensure the health and safety of all personnel involved.
