Maxfil-31SB is a low alloy steel flux cored wire designed for welding of low & medium tensile steels structures subjected to high dynamic loading with superior impact properties. The wire is used with CO2 shielding and deposits radiographic quality weld metals. The wire produces thin & friable slag covering with shiny bead appearance. Weld deposit contains very low diffusible hydrogen (<4ml/100gm).
Maxfil-31SB is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; D/E/F/G grades of SA-414, Gr.60/Gr.65 steels of SA-515, Gr.60/Gr.65 steels of SA-516, etc. Suitable for ship-building, bridge construction, heavy machineries, pressure vessels & boilers, etc.
