Marsh Nickel Alloys, based in Canberra, Australia, stands out as a top-notch manufacturer and supplier of high-quality Inconel 718 tubing. Thanks to their cutting-edge fabrication technology and rigorous quality standards, they produce tubing that’s built to endure extreme conditions. Serving vital sectors like aerospace, power generation, chemical processing, and oil and gas, Marsh Nickel Alloys provides Inconel 718 tubing known for its remarkable strength, corrosion resistance, and durability, making it perfect for demanding applications.
Inconel 718 tubing is mainly made up of nickel (50-55%), chromium (17-21%), iron, niobium, molybdenum, and trace amounts of other alloying elements. This unique blend gives it outstanding resistance to oxidation, corrosion, and high-temperature degradation. On the mechanical side, Inconel 718 tubing boasts high tensile strength, excellent fatigue resistance, and toughness, ensuring it performs well even under thermal cycling and in harsh environments. Its ability to maintain strength at elevated temperatures makes it a go-to choice for critical applications.
