316L Stainless Steel Tubes Supplier and Exporter | UNS S31603, SUS 316L & DIN 1.4404 | Leoscor Alloy Pipes
316L Stainless Steel Tubes are low-carbon austenitic stainless steel tubes designed for applications requiring excellent corrosion resistance, superior weldability, and reliable performance in aggressive environments. The low carbon content helps reduce carbide precipitation during welding, making these tubes suitable for welded structures and critical industrial applications.
Leoscor Alloy Pipes is a trusted manufacturer, stockist, supplier, and exporter of SS 316L Tubes, offering high-quality seamless and welded tube solutions for industries such as marine, chemical processing, pharmaceutical, food processing, and heat exchanger applications.
316L Stainless Steel Tubes are the low-carbon version of 316 stainless steel tubes, containing chromium, nickel, and molybdenum as major alloying elements. The addition of molybdenum improves resistance against pitting and crevice corrosion, especially in chloride-rich and marine environments.
The reduced carbon content improves welding performance and helps maintain corrosion resistance after fabrication. Due to these properties, SUS 316L Tubes are widely used in applications where long-term durability, corrosion resistance, and hygienic performance are required.
316L Stainless Steel Tubes are available in seamless, welded, ERW, and EFW forms. They can be supplied in various shapes including round, square, rectangular, oval, and hollow sections. Different finishes such as cold drawn, hot rolled, cold rolled, annealed, pickled, and electropolished are available according to application requirements.
