INCONEL 718 SPECIFICATIONS
Inconel 718 Threaded Tee, Inconel 718 Threaded Forged Fittings, ASTM B564 Inconel 718 Threaded Elbow, Inconel 718 Hexagonal Plug, 718 Alloy Threaded Inconel 718 are oxidation-corrosion-resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies
