Type 304L is a lower carbon variant of Grade 304-the steel can be welded without the resulting issue of carbon precipitation. As a result, Type 304L stainless steel is a sort after material for use in severely corrosive conditions. Weld annealing is only necessary in applications where stress loads are excessive.
