TIG
Solid Wire Electrode BA-MIG 347Si for MIG/MAG Welding
Classification:
EN ISO 14343-A: G 19 9 Nb Si
SFA 5.9 / AWS A5.9: ER347Si
Main Application
BA-TIG 347Si is a solid wire rod for GTAW with higher Si content than BA-TIG 347, suitable to weld 18Cr/10Ni stabilized with Ti or Nb austenitic stainless steels grades 321 and 347. Also suitable for welding similar unstabilized grades 304 or 304L. BA-TIG 347Si has high resistance to intergranular corrosion.
