Product Overview
Introduction To AL 6XN / UNS N08367 / W.Nr. 1.4529
MOKSH TUBES & FITTINGS LLP is a trusted manufacturer, supplier, exporter, importer, and stockist of AL 6XN Alloy (UNS N08367) products including Pipes & Tubes, Pipe Fittings, Flanges, Sheets & Plates, Coils, Wires, Round Bars, Forged Components, Fasteners, Welding Electrodes, and custom-engineered parts.
AL 6XN is a superaustenitic stainless steel designed for superior corrosion resistance in aggressive chloride environments, especially where standard stainless steels (like 316L) are inadequate. It is known for its high nickel (24%), molybdenum (6.3%), and nitrogen content, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC). Its strength, formability, and weldability make it ideal for critical applications in chemical processing, marine environments, pulp & paper, food, and pharmaceutical industries.
