Stainless Steel 317L Sheets, UNS S31703 Plates Supplier & Exporter

STAINLESS STEEL 317L SHEETS AND PLATES GENERAL PROPERTIES:

317L is a molybdenum bearing, low carbon content "L" grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

STAINLESS STEEL 317L SHEETS AND PLATES APPLICATIONS:

• Flue-gas desulfurization systems
• Chemical process vessels
• Petrochemical
• Pulp and Paper
• Condensers in power generation

STAINLESS STEEL 317L SHEETS AND PLATES CORROSION PROPERTIES:

317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion. Resistance increases with molybdenum alloy content. 317L is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C). At temperatures under 100°F (38°C) this alloy has excellent resistance to solutions of higher concentration. However, service tests are recommended to account for the affects of specific operating conditions that may affect corrosion behavior. In processes where condensation of sulfur-bearing gases occurs, 317L is much more resistant to attack at the point of condensation than conventional alloy 316. The acid concentration has a marked influence on the rate of attack in such environments and should be carefully determined by service tests.

STAINLESS STEEL 317L SHEETS AND PLATES WELDING:

317L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of 317L, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of 317L should be used to weld 317L steel.

STAINLESS STEEL 317L SHEETS AND PLATES CHARACTERISTICS:

• Improved general and localized corrosion to 316L stainless
• Good formability
• Good weldability
