Inconel 718 tube is an age-hardenable nickel-chromium-iron alloy also containing significant amounts of niobium, molybdenum, titanium and aluminum. It combines good corrosion resistance with extremely high strength. Typical applications include heat exchangers and O-rings.Alloy 718 ASTM B163, is an austenitic nickel-based superalloy. Alloy 718 nickel tubing exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF.
