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.

Inconel® 718 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.
