Harris Products Group, 317LT30, TIG Welding Alloy, Stainless Steel 317L, 0.03% C max, 87,000 psi tensile, High Molybdenum

317L stainless steel TIG (GTAW) welding alloy content is somewhat higher than ER316, particularly in molybdenum. The 0.03% maximum carbon content increases resistance to intergranular corrosion due to carbide precipitation. 317L provides severe corrosion resistance to sulfuric and sulfurous acids and their salts. This alloy is often used in the chemical and paper industries. Conforms to AWS A5.9 ER 317L.
