Max Tube Fittings is a reliable manufacturer and supplier of Inconel 718 Tube Fittings based in Delhi, India. We pride ourselves on delivering top-notch fittings that are crafted for high-performance applications. Made from Inconel 718, a nickel-chromium alloy that hardens with heat, these tube fittings boast impressive strength, excellent resistance to corrosion, and remarkable fatigue and creep rupture properties. They’re built to endure extreme conditions, high pressure, and elevated temperatures, ensuring secure and leak-proof connections. Commonly found in aerospace, chemical processing, power generation, marine, and oil & gas sectors, Inconel 718 Tube Fittings are perfect for critical operations that demand durability and reliability.
Inconel 718 Tube Fittings are mainly made up of nickel (50–55%), chromium (17–21%), along with iron, niobium, molybdenum, titanium, and aluminum. This special combination gives them outstanding resistance to oxidation and corrosion, while also allowing them to maintain strength at temperatures reaching up to 700°C. The alloy can achieve a tensile strength of up to 1375 MPa and a yield strength of around 1035 MPa, along with excellent elongation and toughness. It also shows impressive resistance to creep, stress-corrosion cracking, and is easy to weld. These mechanical properties make Inconel 718 Tube Fittings a dependable choice for high-temperature, high-pressure, and corrosive environments.
