Same as ER308. The nominal composition (wt.-%) of this classification is 21 Cr, 10 Ni. Commercial specifications for filler and base metals vary in the minimum alloy requirements; consequently, the names 18-8, 19-9, and 2010 are often associated with filler metals of this classification. This classification is most often used to weld base metals of similar composition, in particular, Type 304. ER308L. This classification is the same as ER308, except for the carbon content. Low carbon (0.03 percent maximum) in this filler metal reduces the possibility of intergranular carbide precipitation. This increases the resistance to intergranular corrosion without the use of stabilizers such as niobium or titanium. Strength of this low-carbon alloy, however, is less than that of the niobiumstabilized alloys or Type 308H at elevated temperatures. Steel seal of AWS Classification "ER308L" , the letter is stamp at the end of the rod, but only the size above (sometimes include) 1/16".
