Type 304L is a lower carbon variant of Grade 304 – the steel can be welded without the resulting issue of carbon precipitation (precipitation of chromium carbide as heat is applied during the welding process which depletes the chromium element of the steel thus reducing its anti-corrosive/oxidation effectiveness).As a result, Type 304L stainless steel is a sought after material for use in severely corrosive conditions. Weld annealing is only necessary in applications where stress loads are excessive.
