317L Stainless Steel 


 317L Stainless Steel 
 317L (00Cr19Ni13Mo3, UNS S31726) alloy is a molybdenum-based austenitic stainless steel. With the conventional chromium - nickel austenitic stainless steel alloys such as 304, compared with more resistance to chemical corrosion. In addition, compared with conventional stainless steel, 317L alloy has a higher ductility, resistance to stress corrosion, compressive strength and high temperature performance. It is a low carbon level or L level, this level has in the process of welding and heat treatment during the allergy of the role of performance. 317L steel 316L has relatively good water resistance and SCC resistance, used in Chemical ship, Reactor and other chemical products need high corrosion resistance of chemical equipment. SUS317L mechanical properties: YS (Mpa) ≥ 176, TS (Mpa) ≥ 480, EL (%) ≥ 40, Hv ≤ 200 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
