Stainless Steel Filler Wire

347 / 347 H



SUPER MIG 347/347H is a G 19 9 Nb / ER 347H type solid MIG welding wire, supplied precision layer wound, depositing a Niobium stabilized 19Cr 9Ni weld metal, suitable for use with Ar+2%O2 or Ar+0.5…5%CO2 mixed shielding gases. SUPER MIG 347/347H is used for welding of 321H and 347H austenitic stainless steels and similar steel , mainly used in applications including the fabrication of pipe, plate and vessels. The weld metal has a high resistance to corrosive media at service temperatures <400°C. The presence of niobium reduces the propensity of intergranular chromium carbide precipitation and thus reduces the susceptibility to intergranular corrosion.
