ER347
AWS A5.9 ER347
EN ISO 14343-A : W 19 9 Nb
Description：
A stainless steel gas shielded welding wire 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 contain Nb or nickel-chrome alloys which Ti as the stabilized element .
