AK-ER347L
Standard：
EN ISO 14343-A:G 19 9 Nb
AWS A5.9 ER347L
GB/T 29713 S347L
Description: A stainless steel gas shield designed for all position welding, offers better corrosion
resistance than Type 308 wires, used to weld 347 and 321 stainless steel. Niobium (Nb) is used as the
stabilized element to prevent intergranular corrosion.
Application: Used to weld important anti- corrosion steel which contains Nb or nickel-chrome alloys
which Ti as the stabilized element.
