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