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.
