Compared to alloy 316L, alloy 317L has a higher nickel alloy concentration and is an austenitic stainless steel with low carbon and high molybdenum. This alloy was created to withstand the attack of compounds that contain sulfuric acid, and it combines outstanding corrosion resistance with great mechanical qualities and ease of manufacture. In fossil fuel power plants, these alloys are frequently utilized for flue gas desulfurization services. 317L plate has greater creep strength, stress to rupture, and tensile strength at high temperatures when compared to other austenitic stainless steels.
Compared to stainless steel grades like 304 or 316, 317L has better corrosion resistance because of its higher molybdenum and chromium content. It also resists pitting and crevice corrosion caused by chloride and is resistant to phosphoric acid, sulfuric acid, and these acids. This grade of 317's low carbon content also confers resistance to sensitization during welding, enabling it to preserve its grain boundary corrosion resistance and avoid intergranular stress corrosion cracking. Although the 317L Plate cannot be heat-treated to harden, it can be cold-worked.
Properties of 317L Plates
This alloy has exceptional corrosion resistance in hostile conditions and also protects against corrosion from a variety of substances. The corrosion and oxidation resistance of SS 317L PLATES is good. Additionally, it provides significantly better resistance to general corrosion caused by substances like chloride, such as pitting. Stainless Steel 317L Plates have strong resistance to solutions with greater concentrations and combine outstanding fabricability with high mechanical qualities. It is a suitable option for a variety of applications in industries due to its enhanced corrosion resistance, high formability, and great formability.
