ER308/308L
Alloy Type: A5.9, STAINLESS STEEL Bare, Cored and Stranded Electrodes
ER308/308L is used for welding types 304, 304L, 308, and 308L stainless steels. It is very similar to type 308 but has a carbon content held to a max of .03% to avoid carbide precipitation. This product can also be used for welding types 321 and 347 stainless steels. This wire is suitable for applications at cryogenic temperatures.
