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.
ER308LSI has the same analysis as ER308L but with a higher silicon content. The higher silicon
content improves arc stability, bead appearance and wetting action. ER308LSI produces
exceptionally smooth welds for applications that require a good cosmetic appearance. This product is used primarilywith welding grades 304 and 308.
ER316/316L is used for welding types 316 and 316L stainless steels. It has a maximum carbon
content of .03% to reduce the possibility of formation of intergranular carbide precipitation. This low carbon alloy is not as strong as 316H at elevated temperatures. This filler metal is primarily used for welding low carbon molybdenum bearing austenitic alloys.
