Inconel 718 Hex Bolts (UNS N07718, WNR 2.4668)

Inconel 718 Hex Bolts are premium, high-performance fasteners manufactured from a high-strength, precipitation-hardenable nickel-chromium alloy. This superalloy, UNS N07718, is characterized by exceptional yield, tensile, and creep-rupture properties at temperatures up to $1300^\circ\text{F}$ ($704∘C). The presence of iron, niobium, and molybdenum, along with controlled additions of aluminum and titanium, allows these Alloy 718 fasteners to be strengthened by a simple heat treatment process. Due to their outstanding mechanical strength and resistance to corrosive environments, including stress-corrosion cracking, Inconel 718 bolts are extensively used in critical applications like jet engine components, gas turbines, rocket motors, and downhole oil and gas equipment. Zeron Fastners specializes in supplying these highly reliable fasteners, manufactured to exacting aerospace and industrial standards.
