Product Description
Inconel 718 Seamless Tube
The offered Inconel 718 Seamless Tube is a nickel-based alloy that has been precipitation hardened. It is used in the aerospace industry. In addition to having extremely high yield strength and tensile strength, this tube also has excellent creep-rupture properties, making it a perfect choice for use in various industrial applications. Welding an age-hardened Inconel metal, however, can result in the formation of a heat-affected region. Similar to the welding operation, our Inconel 718 Seamless Tube can be easily machined in either the annealed or the age-hardened condition, depending on their size and shape. In general, machining our tube in age-hardened operational conditions results in a better surface finish than machining it in a soft state. Meanwhile, manufacturing and annealed condition tube can result in elongated tool life.
Unmatched Strength and Heat ResistanceInconel 718 Seamless Tubes exhibit exceptional heat resistance up to 700C, coupled with a minimum yield strength of 1035 MPa and tensile strength of 1240 MPa. This ensures reliable performance under high-pressure and high-temperature conditions, typical in aerospace and industrial applications. Its polished and bright finish also adds to its suitability for demanding operations.
Custom Fabrication for Diverse ApplicationsManufacturers offer Inconel 718 seamless tubes in customizable sizes and thicknesses ranging from 0.5 mm to 20 mm and diameters from 6 mm to 219 mm. With excellent cold and hot formability, these tubes can be tailored for unique requirements in sectors such as energy, chemical processing, and gas turbine engineering.
Corrosion and Oxidation ProtectionComposed primarily of nickel, chromium, and alloying elements like niobium and molybdenum, Inconel 718 provides outstanding resistance to corrosion and oxidation. This characteristic enables long service life even in chemically aggressive or extreme environments, minimizing maintenance and replacement cycles.
