Stainless Steel 317 Welded Tubes are austenitic stainless steel tubes containing chromium, nickel and a higher level of molybdenum than 316 stainless steel. Grade 317, identified by UNS S31700, is designed for applications requiring enhanced resistance to corrosion, pitting and chemical attack.
The higher molybdenum content of Stainless Steel 317 provides improved resistance to localized corrosion and many aggressive chemical environments. The alloy also offers good strength, ductility and weldability, making it suitable for fabricated tubular components used in demanding industrial services.
Stainless Steel 317 Welded Tubes can be supplied according to applicable ASTM and ASME specifications, depending on the product form, dimensions and service requirements. These tubes are available in different outside diameters, wall thicknesses, lengths and finishes to meet specific project requirements.
Stainless Steel 317 Welded Tubes are commonly used in chemical processing, petrochemical equipment, pulp and paper plants, power generation, food processing and industrial fluid-handling systems. Their enhanced corrosion resistance makes them suitable for environments where standard stainless steel grades may not provide the required performance.
