304L Stainless Steel Tubes

Home 304L Stainless Steel Tubes

304L Stainless Steel Tubes Supplier and Exporter | UNS S30403, DIN 1.4307 & SUS 304L | Leoscor Alloy Pipes

304L Stainless Steel Tubes are low-carbon austenitic stainless steel tubes designed for applications requiring excellent corrosion resistance, good weldability, and reliable performance after fabrication. The reduced carbon content helps minimize carbide precipitation during welding, making these tubes suitable for welded structures and industrial equipment.

Leoscor Alloy Pipes is a trusted manufacturer, stockist, supplier, and exporter of SS 304L Tubes, offering seamless and welded tube solutions for various industries. Our 304L stainless steel tubes are available in different sizes, wall thicknesses, surface finishes, and shapes according to customer requirements.

304L Stainless Steel Tubes are a low-carbon version of the standard 304 stainless steel grade. These tubes contain chromium and nickel as major alloying elements, providing excellent resistance against corrosion, oxidation, and general industrial environments.

The lower carbon content improves weldability and helps maintain corrosion resistance after welding processes. Due to these properties, SS 304L Tubes are widely used in chemical equipment, food processing systems, heat exchangers, nuclear energy applications, and fabrication industries.

304L Stainless Steel Tubes are available in seamless, welded, ERW, and EFW forms. They can be supplied in different shapes including round, square, rectangular, oval, and hollow sections with finishes such as cold drawn, hot rolled, annealed, and pickled.
