Benefits and industry first

• Customers are provided with options that best suit their    needs with design and specification selected against the background of cargoes carried.
• By matching design and specification with the cargoes, customers may expect expenses associated with shell repairs to taper down as will the cost of non-utilization.
• By matching corrosive cargoes with shell material with greatly enhanced corrosion resistance owners can enjoy longer service live of their assets in comparison to regular ISO tank containers.
• The preservation of the tank shell thanks to its enhanced corrosion resistance above the current market standard austenitic grade ASTM 316L  EN 1.4401 provides REMANUACTURE prospects with the much needed credibility
• For service that requires an austenitic grade of stainless steel that offers corrosion resistance significantly above ASTM 317L  EN 1.443 there is austenitic grade ASTM 904L  EN 1.4539

Elevated corrosion resistance Stainless steel Type 317L, UNS S31703

A low-carbon, molybdenum-containing austenitic stainless steel with improved resistance to chlorides relative to

Type 304L and Type 316L stainless steels.

Description

Type 317L is a molybdenum-containing austenitic stainless steel intended to provide improved corrosion

resistance relative to Type 316L in highly corrosive process environments, particularly those containing chlorides

or other halides. The low carbon permits Type 317L to be welded without sensitization to intergranular corrosion

resulting from chromium carbide precipitation in the grain boundaries. Type 317L is non-magnetic in the annealed

condition but may become slightly magnetic as a result of welding.

Corrosion Resistance

Type 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.
