Inconel 718 is a nickel-based super alloy that is well suited for applications requiring high strength in temperature ranges from cryogenic up to 1400°F. Inconel 718 also exhibits excellent tensile and impact strength.

Inconel 718 (or Alloy 718) is a special type of high-strength superalloy with a nickel-chrome base that makes it resistant to corrosion, high pressure and extreme temperatures of up to 700°C.

The material is composed of 50-55 % nickel, 17-21% chromium, 4.75-5.5 % niobium and tantalum, and trace amounts of molybdenum, titanium, cobalt, aluminium, manganese, copper, silicon and other elements.

Because of its unique properties, Inconel 718 has become useful in a wide range of applications ranging from manufacturing operations to military equipment and the aerospace industry.
