Product Overview
Introduction To Hastelloy G-30 /Alloy G-30 / UNS N06030
MOKSH TUBES & FITTINGS LLP LLP is a leading manufacturer, supplier, exporter, importer, and stockist of ALLOY G-30 (UNS N06030) products, available in various forms such as Pipes & Tubes, Pipe Fittings, Flanges, Fasteners, Sheets & Plates, Coils, Wires, Round Bars, Flat Bars, Angles, Channels, Welding Rods, Wire Mesh, and special custom-made components.
HASTELLOY G30 is a nickel-chromium-iron alloy with high additions of cobalt, molybdenum, and copper, developed specifically for improved corrosion resistance in strongly oxidizing acid environments, especially phosphoric and nitric acids. It offers significantly better performance than ALLOY G-3 in many highly oxidizing chemical environments and resists intergranular corrosion even after welding. Known for its exceptional resistance to mixed acid environments, HASTELLOY G30 also retains good fabricability and is a popular choice in fertilizer production, chemical processing, and pollution control systems.
