317L (00Cr19Ni13Mo3, UNS S31726) alloy is an austenitic stainless steel based on molybdenum. It has stronger resistance to chemical corrosion compared to conventional chromium nickel austenitic stainless steel such as 304 alloy. In addition, compared to conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength, and high-temperature resistance. It is low carbon grade or L grade, which has anti Sensitization performance during welding and heat treatment.
317L steel has good seawater and SCC resistance compared to 316L, and is used in chemical ships, chemical products, Reactors, and other chemical equipment that require high corrosion resistance
SUS317L Chemical composition: carbon (C) ≤ 0.030, manganese (Mn) ≤ 2.00, nickel (Ni) 11.0-15.0, silicon (Si) ≤ 1.00, phosphorus (P) ≤ 0.045, sulfur (S) ≤ 0.030, chromium (Cr) 18.0-20.0, molybdenum (Mo) 3.0-4.0
