Stainless steel 317L are the second most commonly used stainless steel grades after 304/304L, being a higher version of 304 with addition of molybdenum and slightly higher content of nickel. The features of 317 are similar to that of 304, the only difference is that 317 is stronger at elevated temperatures. 317L Stainless Stel is also known as UNS S31700 and has a low caron austenitic nickel-chromium stainless steel with additions of molybdenum and copper and that is why They are used especially in severe corrosive conditions.

The key features of Stainless Steel 317L
