Material Summary
317L (UNS S31703) is a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. The high levels of these elements assure the steel has superior chloride pitting and general corrosion resistance to the conventional 304/304L and 316/316L grades. The steel provides improved resistance relative to 316L in strongly corrosive environments containing sulfurous media, chlorides, and other halides.
The low carbon content of 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.
The grade 317L is non-magnetic in the annealed condition. It cannot be hardened by heat treatment; however the material will harden due to cold working. 317L can be easily welded and processed by standard shop fabrication practices.

Grade 317L is commonly used to handle sulfur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil, and many chemical compounds. Some other applications that use 317L include:
1.generally export packing
-packed by knitting strips in bundles
2.It is suggested that the pipes OD under 25MM or Less than container shipment are packed by plywood cases, which can protect pipes better.
