Description
317L Stainless Steel Pipe – High Corrosion Resistance, Low Carbon Alloy | KCM
The 317L Stainless Steel Pipe by KCM is designed for superior performance in highly corrosive and high-temperature industrial environments. Alloyed with higher molybdenum content and low carbon levels, 317L provides outstanding resistance to sulfuric acid, chlorides, and other aggressive chemicals, ensuring reliable performance in applications where standard austenitic stainless steels may fail.
Thanks to its low carbon content, the pipe offers enhanced resistance to intergranular corrosion, especially in weld zones, making it suitable for critical fabrication and piping systems in the chemical processing, pulp and paper, food processing, and pharmaceutical industries.
Manufactured to precise industry standards, KCM’s 317L pipe ensures dimensional accuracy, weldability, and surface finish. Available in a wide range of diameters and wall thicknesses, it is supplied in both seamless and welded forms, allowing for flexible installation in new builds or retrofits.
