Inconel 718 Fasteners

Inconel 718 Fasteners Manufacturer & supplier

Premium-grade Inconel 718 fasteners, built to function under the most demanding circumstances, are our specialty at Synergy Fasteners. Our Inconel 718 fasteners, which are made for high-strength applications in the nuclear, oil and gas, power generation, and aerospace industries, provide exceptional performance in harsh conditions.

At temperatures as high as 704°C (1300°F), the nickel-chromium alloy Inconel 718 (UNS N07718 / W.Nr. 2.4668) shows outstanding fatigue resistance, creep-rupture strength, and high tensile strength. This age-hardenable alloy is one of the most trustworthy supplies for crucial fastening applications because it combines stability, corrosion resistance, and weldability.
