AWS: SFA 5.20 E70T-5C
EN ISO CODE: 17632-B T493T5-0CA-K
Maxfil-31B is a low alloy steel flux cored wire designed for welding of low & medium tensile steels structures subjected to dynamic loading. The wire gives good performance under CO2 shielding with radiographic quality weld deposits. The wire produces thin & friable slag covering with shiny bead appearance.
Maxfil-31B 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 shipbuilding, bridge construction, pressure vessels & boilers, etc.
