Stainless steel Mig Welding Wire
RAAJMIG ER 347
Stainless steel continuous & cut length solid welding wire for MIG/TIG welding
CLASSIFICATION : AWS/SFA-5.9: ER347, BS 19.9Nb
DIN 8556: WK. 1.4551
CHARACTERISTICS : ER347 are Niobium stabilized 18Cr-8Ni type welding wires are designed to produce excellent weld appeal with Argon+O2 or CO2 mixtures as shielding gas.
APPLICATION : ER 347 is Niobium stabilized grades are suitable for MIG/TIG/ SA welding of type AISI 321 and the 18/8 types which are likely to be subject to temperatures of above 400°C but not more than 850°C. The higher Silicon grades give better weld flow & smoother weld beads.
SHIELDING GAS : welding with 100% Ar gas Or Ar+2%O2 gas.
