317L alloy is an austenitic stainless steel based on molybdenum. 317L stainless steel has stronger chemical corrosion resistance than conventional chromium nickel austenitic stainless steel such as 304 alloy. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is a low carbon grade or l grade, which has the performance of anti sensitization during welding and heat treatment. Compared with 316L, 317L steel has good seawater resistance and SCC resistance. It is used in chemical ships, chemical products reactor and other chemical equipment requiring high corrosion resistance.
