Application
ER308L has the same analysis as type 308 except the carbon content has been held to a maximum of .03% to reduce the possibility of intergranular carbide precipitation. ER308L is ideal for welding Types 304L, 321, and 347 stainless steels. This is a suitable wire for applications at cryogenic temperatures.

Note: Parameters for tig welding are dependent upon plate thickness and welding position.
Other shielding Gases may be used for Tig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration.

 

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.
