What is Inconel 718 Sheet?
Inconel 718 Sheet is a nickel-chromium alloy that contains niobium, molybdenum, and titanium additions. It is renowned for its strength, corrosion, and oxidation resistance in high temperatures. Inconel 718 Sheet offers excellent creep rupture strength down to cryogenic temperatures and can be used in static and dynamic applications.
What are the features of the Inconel 718 Sheet?
The features of the Inconel 718 Sheet include the following:
• Good formability.
• Weldability.
• High fatigue strength under cyclic loading conditions.
• Good corrosion resistance in acids like sulphuric acid and phosphoric acid.
• Oxidation resistance up to 1300°F (704°C).
The sheet also has excellent cold workability due to its ability to harden by strain
aging.

What are the applications of the Inconel 718 Sheet?
Inconel 718 Sheet has a range of applications, including cryogenic tanks and components, gas turbine parts, aircraft engine components (including landing gear), rotating discs, pump bodies and impellers, valves and valve components, springs, and fasteners. This 718 Inconel Sheet is also used in chemical processing for heat exchangers, piping systems, and process vessels.
What are the advantages of the Inconel 718 Sheet?
The advantages of Inconel 718 Sheet include outstanding mechanical properties over a wide range of temperatures in static and dynamic conditions. The sheet offers excellent weldability with no pre-or post-weld treatments required to maintain its strength or corrosion resistance. It also has good formability when cold worked, which makes it easier to manufacture complex shapes such as curved components or riveted connections. In addition, Inconel 718 Sheet is a non-magnetic material that provides electrical insulation and reduces interference in electronic applications.
Inconel 718 Sheet is an ideal choice for various applications due to its excellent mechanical properties, formability, and corrosion resistance. Also, these sheets come in multiple thicknesses, including 0.062" to 0.312" (1.58mm to 8mm). The most common Inconel 718 sheet thickness is 1/8" (3.175mm) and ¼" (6.35mm). You can purchase thicker sheets up to 1" (25 mm).
