317L Stainless Steel Pipe
317L Stainless Steel Pipe is a low-carbon, molybdenum-bearing austenitic steel providing superior resistance to pitting and general corrosion compared to 316L, particularly in highly acidic and chloride-rich environments like seawater. The low carbon content ensures excellent weldability without risking intergranular corrosion after joining. This pipe is mandatory for use in severe service applications in the chemical and petrochemical industries, pulp and paper processing (scrubbers), and aggressive marine environments where enhanced resistance to chemical attack is necessary for reliable pipelines and heat exchanger tubing.
