Inconel 718 tubing is a high-strength and corrosion-resistant material that is commonly used in the aerospace, gas turbine, and oil and gas industries. It is a nickel-chromium alloy that also contains significant amounts of iron, niobium, and molybdenum, which give it exceptional mechanical properties even at high temperatures. Inconel®718/Alloy 718 is available in wide variety
of shapes and forms including pipe, tube, fitting, flange, sheet, plate, round
bar, forging stock, flat bar, wire, hexagon. The various forms of UNS N08825 from Hengyang Piping meet different critical standards like ASTM, ASME, DIN, EN
and clients’ specification.
In terms of specifications, Inconel 718 tubing has a W.Nr. 2.4668 designation and an UNS N07718 material grade. This makes it easy to identify and source the appropriate material for a particular application. Key features of Inconel 718 tubing include its excellent strength, durability, and resistance to corrosion and oxidation. It also has good fatigue resistance and can maintain its properties in extreme environments, making it an ideal choice for demanding applications.
Inconel 718 tubing is available in both seamless and welded forms, and can be used for a variety of purposes such as tubing hangers, heat exchangers, and gas turbine engine components. It is also used in forging applications due to its excellent forgeability and workability.
