Stainless Steel 317 is an austenitic chromium-nickel-molybdenum steel that features a higher molybdenum content compared to 316, which enhances its resistance to pitting, crevice corrosion, and chemical attacks. On the other hand, 317L is the low-carbon variant of 317, providing improved weldability and better resistance to intergranular corrosion, particularly after welding or exposure to high temperatures. The ERW pipes made from these grades deliver excellent strength, good formability, and outstanding corrosion performance in environments rich in chlorides and acids. The electric resistance welding process ensures a high-quality weld with minimal additional material, making these pipes perfect for cost-effective, large-scale production.
