Inconel X-718

Inconel X-718 is a nickel super alloy frequently used for cryogenic storage tanks, turbines, down hole shafting and well head parts. High tolerance to extremely high and low temperatures allow inconel 718 to be welded and annealed into products that will withstand extreme conditions. Other uses include jet rocket, nuclear fuel, and pump body components.

Inconel X-718 Applications

• Rings
• Fasteners
• Casings
• Instrumentation components
• Nuclear fuel element spacers
• High-strength bolts

Chemical Composition

Inconel® 718 is made up primarily of nickel (52%). Alloying elements include Iron (19%), Chromium (18%), Columbium+ Tantalum (5%), Molybdenum (3%), Titanium (0.9%), Aluminum (0.5%) with the addition of other elements in trace amounts such as Baron, Cobalt, Copper, Manganese and Silicon.

Physical Properties

Inconel® 718 features a melting point of 2300°c and possesses impressive tensile strength that lends itself well to the wide variety of industrial applications it is involved in such as fasteners, high-strength bolts and nuclear fuel element spacers to name but a few. This is further aided by the alloy's excellent performance in properties such as weldability and creep-rupture.
