(R) Bolts, Screws and Studs, Nickel Alloy, UNS N07718 Work-Strengthened, Tensile Strength 220 ksi Procurement Specification
|Publication Date:||1 August 2020|
This procurement specification covers bolts, screws, and studs made from a work-strengthened corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07718. The following properties are covered:
220 ksi minimum ultimate tensile strength at room temperature
180 ksi minimum ultimate tensile strength at 900 °F
114 ksi tension to 11.4 ksi tension fatigue at room temperature
Primarily for aerospace propulsion systems applications where a good combination of tensile strength, fatigue strength, resistance to relaxation, and shear strength is required for use up to approximately 900 °F.
