MIG
Solid Wire Electrode BA-MIG 347 for MIG/MAG Welding
Classification:
EN ISO 14343-A: G 19 9 Nb
SFA 5.9 / AWS A5.9: ER347
Main Application
BA-MIG 347 is a solid wire electrode for GMAW, 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-MIG 347 has high resistance to intergranular corrosion.
