Inconel 718
Inconel 718 is a precipitation-hardening nickel-chromium-iron alloy with exceptional high-strength, fatigue resistance, and creep-rupture properties at elevated temperatures. It exhibits excellent corrosion resistance, good weldability, and outstanding mechanical stability up to 700°C. It features high tensile and impact strength, as well as superior resistance to oxidation and corrosive media. Widely used in high-temperature and high-stress environments, it is one of the most popular superalloys for critical structural applications.
