Inox 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).

304L Seamless Stainless Steel Tubing
As a result, Inox 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.
Inox 304 and 304L plate and pipes have similar properties and in certain cases are stocked with Dual Certification, where it is concluded that each item has properties and a composition which comply with both steel types. Inox 304H cannot be included in this equation due to the steel’s higher carbon content which is intended for use in elevated temperature applications.
