UNS N07718 Inconel Nickel Alloy Corrosion Resistant For Cold Rolled Plate

Inconel 718 N07718 2.4668 High-strength Corrosion-resistant Nickel Alloy

Inconel 718, widely known as GH4169 in China, is one of the most popular high strength corrosion resistant alloys in China. It also has good mechanical properties at -423° to 1300°F.

Inconel 718 is designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures.

Chemical composition(%)

Character

•  Good mechanical properties – tensile, fatigue and creep-rupture
