317L
317L (00Cr19Ni13Mo3, UNS S31726) are molybdenum-based alloy austenitic stainless steel. With conventional chromium - nickel austenitic stainless steel such as Alloy 304, compared with more resistance to chemical corrosion. In addition, compared with conventional stainless steel, 317L alloys offer higher creep, stress corrosion resistance, compressive strength and high temperature performance. It is the low carbon level or L level, this level has in the process of welding and heat treatment during the sensitization of the role of performance.
  317L steel 316L has relatively good water resistance and resistance to SCC resistance for Chemical ship, Reactor and other chemical products to be high corrosion resistance of chemical equipment.
