    Nickel Alloy 718 / Inconel 718 Seamless Alloy Pipe 20ft Length Round Shape

    ASTM B444 Alloy 625 / UNS N06625 Nickel Alloy SMLS Tube WNR 2.4856 Tubing

    Alloy 718 (UNS N07718, W Nr 2.4668) is an austenitic nickel-based superalloy. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. Alloy 718 is used in applications that require high strength such as parts for jet engines and high speed airframe parts such as wheels, buckets, spacers and high temperature bolts and fasteners.


    Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures. This nickel alloy is used from cryogenic temperatures up to long term service at 1200° F. One of the distinguishing features of Inconel 718’s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. The addition of niobium acts with the molybdenum to stiffen the alloy’s matrix and provide high strength without a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium. This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition. This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors.

    Thus precipitation-hardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
