SS FITTINGS

317L

Overview: 317L is a molybdenum-containing austenitic stainless steel. Its corrosion resistance is better than SS 304L and 316L. The low carbon provides resistance to sensitization during welding and other thermal processes.
Applications: Petrochemical, Pulp and Paper, Flue-gas desulfurization systems, Chemical process vessels, etc.
