Description: AFM E309L-16 has the same composition of weld metal deposited by AFM E309-16
electrodes, except for the restricted carbon content. The 0.04 percent maximum
carbon content of these weld deposits reduces the possibility of intergranular
carbide precipitation and thereby increases the resistance to intergranular
corrosion without the use of stabilizers such as columbium (niobium) and
titanium. AFM E309L-16 is not as strong at elevated temperature as the
columbium-stabilized alloys or high carbon content AFM E309-16 deposits.
