Application

SUPERMIG 347Si/347LSi

SUPER MIG 347Si/347LSi is a G 19 9 Nb Si / ER 347Si 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 347Si/347LSi is used for welding of 321 and 347 austenitic stainless steels and similar steel , mainly used in a range of applications including the fabrication of pipe, plate and vessels. SUPER MIG 347Si/347LSi weld metal has a high resistance to corrosive media at service temperatures <400°C and the presence of niobium reduces the propensity of intergranular chromium carbide precipitation and thus reduces the susceptibility to intergranular corrosion. The increased silicon content results in increased weld pool fluidity to give a smooth deposit appearance.
