As a senior fastener engineer, I can confirm that the Inconel 718 Stud from our Chinese Factory represents a benchmark in high-performance bolting solutions. Manufactured to ASTM B637 UNS N07718, this 1-inch-diameter, 180-mm-long stud is engineered for mission-critical joints where thermal stability and load retention are non‑negotiable.
What sets this fastener apart is its precipitation-hardened structure, which delivers yield strength above 550 MPa at 650 °C and still holds 482 MPa at 700 °C—far outperforming standard 304 stainless or A286. In creep‑rupture testing, it surpasses 100 hours under 700 °C/689 MPa stress, with a rupture strength of 620 MPa at 650 °C, outlasting Waspaloy and Haynes 282 in comparable cycles. Fatigue life is equally robust, with a 650 °C fatigue limit of 350–400 MPa and low notch sensitivity (Kf ≈ 2.5), making it inherently reliable for threaded connections under vibration.
Typical deployments include aircraft engine turbine bolts, combustion chamber connectors, gas turbine blade fasteners, nuclear reactor internals, and high‑temperature/high‑pressure petrochemical piping. The Chinese Factory leverages precise forging and aging cycles to achieve an optimal balance of strength, ductility, and oxidation resistance, ensuring consistent mechanical properties from batch to batch.
With a competitive price of USD 59–99/kg, low MOQ (10 kg), full customization, and delivery within 7–30 days, this Inconel 718 Stud offers a cost‑effective alternative without compromising aerospace‑grade performance. For engineers specifying elevated‑service fasteners, this product eliminates the trade‑off between creep life and fatigue endurance—delivering dependable joint integrity up to 700 °C for both short‑term peaks and long‑term steady operation.
