Stainless Steel 317 and 317L Welded Tubing is crafted for situations where you need top-notch corrosion resistance and dependable performance, especially in tough environments. Thanks to advanced welding techniques, this tubing boasts consistent weld quality, smooth inner surfaces, and precise dimensions. With a higher molybdenum content than standard austenitic grades, it stands up well against chemical attacks, making SS 317 and 317L welded tubing a reliable option for critical industrial applications that require durability and long-lasting service.
These austenitic alloys, Stainless Steel 317 and 317L, are made with chromium, nickel, and extra molybdenum to provide excellent protection against pitting and crevice corrosion. The 317L grade has a lower carbon content, which not only improves weldability but also reduces the chances of intergranular corrosion. Both grades offer solid tensile and yield strength, along with great ductility and toughness. They maintain their mechanical stability even under pressure and at moderate to high temperatures, ensuring they perform consistently in demanding conditions.
