AWS ER308L
Description:
ER308L is similar to ER308 but contains an average .02% carbon producing a weld deposit with good resistance against intergranular corrosion caused by carbide precipitation. ER308L is commonly used for welding AISI types 304L, 308L, 321 and 347.
AWS ER309L
Description:
ER309L is similar to ER309 but contains an average .02% carbon to provide a weld deposit that will offer good resistance against intergranular corrosion caused by carbide precipitation. ER309L is excellent for buttered passes and overlay work. Typical applications include those of ER309 welding wire.
AWS ER316L
Description:
ER316L is similar to ER316 but contains an average .02% carbon producing a weld deposit with excellent resistance against intergranular corrosion caused by carbide precipitation.
Application:
ER316L is used for welding AISI types 316L and 318 that may be exposed to organic and inorganic acids.
