Type 304 and 304L Stainless Steel Explained

Jan 11, 2020· Type 304L Stainless Steel. Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing.
