Material Introduction 317L (00Cr19Ni13Mo3, SUS317L) is a molybdenum-based alloy austenitic stainless steel. It is with the conventional chromium - as compared to nickel austenitic stainless steel alloy 304, with stronger resistance to chemical corrosion. In addition, compared with conventional stainless steel, 317L alloys have higher ductility, stress corrosion resistance, compressive strength and high temperature performance. It is a low carbon grade or L levels, this level have during the process of welding and heat treatment of the role of anti-allergy properties. 317L 2 Mechanical properties Mechanical properties: YS (Mpa) ≥176, TS (Mpa) ≥480, EL (%) ≥40, Hv≤200 3 chemical composition of 317L 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 4 uses 317L steel species relative 316L has a good seawater resistance and SCC resistance for Chemical ships, chemical products and other required Reactor high corrosion chemical equipment. 5 specifications 317L cold-rolled plate (volume) 2B (BA), 8K mirror, gilt.
