Inconel 718 U-Bolts & J-Bolts (UNS N07718, WNR 2.4668)

Inconel 718 U-Bolts & J-Bolts are specialized fasteners primarily used as pipe clamps or structural anchors to secure piping, tubes, or other structural components to their supports. Formed from the high-strength, age-hardenable Nickel Alloy 718 (UNS N07718), these fasteners exhibit outstanding resistance to creep and rupture at service temperatures up to $700∘C ($1300^\circ\text{F}$). The high nickel and chromium content provides exceptional defense against stress-corrosion cracking and general corrosion in aggressive media, making them indispensable in marine, chemical, and petrochemical environments. Zeron Fastners fabricates these Inconel 718 pipe supports to precise dimensions, ensuring reliable, long-lasting performance in critical industrial applications, including securing high-pressure process lines and heat exchanger bundles.
