Stainless Steel 317 & 317L

317L is a molybdenum bearing, low carbon content “L” grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes.

317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.
