GB/T 17853 E347T1-1
Description: E347T1-1 is a stainless steel gas shielded flux-cored wire designed for all positional welding, can be used to weld 347 and 321 stainless steel. The weld deposit has 5- 15% ferrite. 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.
