MAXFIL 71A1

AWS: SFA 5.29 E71T1-A1C/M

EN ISO CODE: 17632-B T493T1-1CA 2M3

Maxfil-71A1 is an all position low alloy steel flux cored wire designed for welding of 0.5% Molybdenum and 1% Chromium and 0.5% Molybdenum steels. The wire gives optimum performance under both 100% CO2 and 80%Ar:20%CO2 gas shielding with radiographic quality weld deposits. The wire produces full slag covering. Slag detachability is very good and is of fast freezing nature.

Maxfil-71A1 is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; Gr. F1 of SA-182 and SA-336, Gr. A of SA-204, Gr. T1/T1a/T1b of SA-209, Gr. WC1 of SA-217, Gr. A of SA-302, Gr. P1 of SA-335, Class 1 of A grade of SA-533, etc.
