ASTM A312 TP304L Welded Stainless Steel Tubing SS304 Pipe
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.
This steel Grade is found in a variety of commercial sectors,
particularly in the chemical industry..

304L is a variant of 304 stainless steel with lower carbon content
and is used for welding applications. The lower carbon content
minimizes carbides precipitation in the heat-affected zone near the
weld, which can lead to intergranular corrosion (welding erosion)
in stainless steel in some environments.
