The difference between grade 317 and 317L is the percentage of carbon in their chemical composition. This difference in chemical composition is the deciding factor for a welded alloy grade. Since the content of carbon in 317L Stainless Steel Sheet is low, it is used for welding. The lower content of carbon promotes weldability, as the lack of carbon discourages the formation of chromium carbide precipitates. Thus using a low carbon version i.e. grade 317L Stainless Steel Plate for welding prevents intergranular corrosion. Another variation of grade 317 is the 317Lmn Stainless Steel Sheet, which contains a higher content of molybdenum and nitrogen in comparison to 317L.
The benefits of using this new alloy include its resistance to pitting corrosion as well as resistance to those environments that contain chlorine. Chlorine is acidic and often has a negative impact on conventional alloys such as grade 304. The combination of nitrogen and molybdenum in the ASTM A240 317L Shims also curbs the occurrence of crevice corrosion in marine environments. The most suitable use for this alloy is in the field of air pollution control. The corrosion resistance properties in combination with good mechanical strength are why many grade 317L Sheet Suppliers recommend using these sheets or plates to build flue gas desulfurization systems.
