317L Stainless Steel Tubes Supplier and Exporter | UNS S31703, DIN 1.4438 & EN 1.4438 | Leoscor Alloy Pipes
317L Stainless Steel Tubes are low-carbon austenitic stainless steel tubes designed for applications requiring higher corrosion resistance than standard 304 and 316 stainless steel grades. The increased molybdenum content improves resistance against pitting, crevice corrosion, and chemical attack, making these tubes suitable for harsh industrial environments.
Leoscor Alloy Pipes is a trusted supplier, stockist, and exporter of SS 317L Tubes, offering seamless and welded tube solutions for industries where durability, corrosion resistance, and long-term performance are required. Our tubes are available in different sizes, wall thicknesses, finishes, and shapes according to customer requirements.
317L Stainless Steel Tubes are low-carbon versions of 317 stainless steel tubes developed for highly corrosive environments. The combination of chromium, nickel, and higher molybdenum content provides improved resistance against acids, chlorides, and chemical processing conditions.
The low carbon content helps reduce carbide precipitation during welding, improving corrosion resistance after fabrication. Due to these properties, SUS 317L Tubes are widely used in chemical processing plants, pulp and paper industries, petrochemical systems, condensers, heat exchangers, and marine applications.
317L Stainless Steel Tubes are available in seamless and welded forms and can be supplied in different shapes including round, square, rectangular, oval, and hollow sections. The selection of tube size, wall thickness, pressure rating, and temperature range depends on the specific application requirements.
