317L Stainless Steel Strip Features:
Alloy 317L (UNS S31703) is a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. The high levels of these elements assure the alloy has superior chloride pitting and general corrosion resistance to the conventional 304/304L and 316/316L grades. The alloy provides improved resistance relative to 316L in strongly corrosive environments containing sulfurous media, chlorides, and other halides.
The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition. With the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700).
Grade 317L stainless steel strip offers excellent machinability because it has high hardness which in turn means that cutting tools do not get dulled easily by the material during machining operations.

317L Stainless Steel Strip Advantages:
1) 317L stainless steel coil has excellent welding characteristics including the ability to be welded using conventional methods or TIG welding.
2) 317L stainless steel coil also has good forming properties making it easy to form into complex shapes using conventional forming techniques.
3) The mechanical properties at room temperature are very similar to those of 316L stainless steel coil.
4) The yield strength of both materials is about 25% higher than 304 stainless steel coil, but the lower yield strength of 316L stainless steel coil limits their use to applications where higher working loads are not expected.
317L Stainless Steel Strip Applications:
1. Air Pollution Control — flue gas desulfurization systems (FGD)
2. Chemical and Petrochemical Processing
3. Explosives
4. Food and Beverage Processing
5. Petroleum Refining
6. Power Generation — condensers
7. Pulp and Paper
