Inconel 718 - Superalloy

Inconel 718 - Superalloy

IN718 is a nickel-based Inconel superalloy, developed to resist most of all high temperatures, usually in cases until 70 % of the absolute melting temperature. It has an excellent creep, corrosion and oxidation resistance as well as a good surface stability and fatigue life.

This superalloy is widely used in the industrial production fields such as aircraft, nuclear, space industry, etc.
