Description: AFM E308L-16 has the same composition of the weld metal of AFM E308-16, except
for the restricted carbon content. The 0.04 percent maximum carbon content of
weld metal deposited by AFM E308L-16 reduces the possibility of intergranular
carbide precipitation and thereby increases the resistance to intergranular
corrosion without the use of stabilizers such as columbium (niobium) or
titanium. A carbon content of 0.04 percent maximum has been shown to be
adequate in weld metal, even though it is recognized that similar base metal
specifications require a 0.03 percent limitation. This low carbon alloy,
however, is not as strong at elevated temperature as the columbium-stabilized
alloys or 304H.
