317L

HuaNickel 317L is a molybdenum-containing austenitic stainless steel with improved corrosion resistance over HuaNickel 304/304L and 316/316L stainless steels. The increased chromium, nickel and molybdenum content on 316L stainless steel improves chloride pitting and general corrosion. By controlling nitrogen addition, 317L can generally meet the mechanical properties of 317 straight grade while maintaining low carbon content.
