Low Alloy Steel Wire

MAXFIL-71W

AWS: SFA 5.29 E71T1-GC

EN ISO CODE:

Maxfil-71W designed for single and multi pass welding on Weathering Corten Weathering A1 steels. The wire burns with smooth arc and low spatter. Weld metal contains extremely low diffusible hydrogen (<4ml per 100gm). The wire gives optimum performance with 100% CO2 shielding and characterized with smooth metal transfer, uniform welding even on vertical-up stringer beads and easy slag removal. The weld metal mechanical properties afford a high degree of security against heavy stress and for welds on thick
