GFC 347


Fluxcored wire for stainless Steel

CLASSIFICATION : AWS/SFA 5.22:E347T1–1/4

TYPICAL APPLICATION :

  • Weld metal 19.5%Cr-10% Ni-Nb which adds Nb in order to reduce carbide precipitation.
  • It is suitable for welding AISI 347, 321, 304L and 302 stainless steel.

Welding Instruction :

  • Dilution of base metal produces ferrite or pure austenitic to increase crack susceptibility.

Shielding gas :

CO2 or (80%Ar+20%CO2 mix gas)

Welding Position: All Positions
