About 317/317L Stainless Steels

Stainless steel 317 (SS317) is a modified version of stainless steel 316 (SS316) with higher molybdenum (Mo) addition to improve the pitting-corrosion resistance as well as enhance its strength. Stainless steel 317L (SS317L) is the low carbon version of SS317 providing improved corrosion resistance relative to stainless steel 316L (SS316L). The low carbon permits SS317L to be welded without sensitization to intergranular corrosion resulting from chromium carbide precipitation in the grain boundaries. Both SS317 and SS317L are widely used in pulp and paper making industry, chemical processing, petrochemical piping and textile industry.
