317 Stainless Steel is an austenitic stainless steel which contains molybdenum. This grade has improved corrosion resistance over 304/304L and 316/316L. 317/317L By controlling the addition of nitrogen, 317L commonly meets the properties of the straight grade 317 except for it’s lower carbon content.
