Stainless Steel 317 and 317L are molybdenum-bearing austenitic stainless steels. Due to the molybdenum content of 3-4%Stainless Steel 317 and Stainless Steel 317L are more resistant to general corrosion and pitting/crevice corrosion than type stainless steel 304. Stainless Steel 317 and Stainless Steel 317L are used in the Food, Pharmaceutical, Marine and Architecture industries.
