Principal Design Features: 317L is a low carbon version of 317 stainless. It possesses the same high strength and corrosion resistance and will produce stronger welds due to its low carbon content. Many users are shifting over to this alloy in lieu of 304 and 316 as availability and cost improves.

Applications: Chemical and petrochemical process equipment, pulp and paper manufacturing and condensers in fossil and nuclear fueled power generation stations.

Machinability: Low speeds and constant feeds will minimize this alloy’s tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.

Welding: All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 317L filler metal for best results.
