Pressure and heat are no match for Inconel 718 socket set screws. These screws handle many extreme environments including those that require oxidation and corrosion resistance.

Inconel 718, also known as Alloy 718, is twice as strong as Inconel 625. It is incredibly corrosion resistant and used at -423°F to 1300°F. This makes it useful for gas engine turbines and cryogenic tanks.

Additionally, due to their nickel-chromium content, Inconel 718 socket set screws have excellent resistance even when combating chloride-ion stress-corrosion cracking. The addition of molybdenum to the alloy helps prevent pitting.

Inconel 718 has also been precipitation hardened. The heating and quenching process is used to change the alloy’s atomic structure, making it stronger by locking the metal’s grain structure in place.
