MAXFIL-40R

AWS: SFA 5.29 E101T1-K3C

EN ISO CODE:

Maxfil-40R is a low alloy steel flux cored wire designed for welding of high strength fine grained quenched & tempered steels to meet sub-zero impact resistance property down to -20°C. The wire is suitable for positional welding application, results easy slag removal and has excellent welders appeal. Weld bead is smooth & uniform and satisfies the requirements of radiographic quality.

Maxfil-40R is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; HY-80, NAXTRA-60/65, T-1, A/B grades of SA-203, A/B/C grades of SA-662, B/C grades of SA-737, etc. This wire is used for fabrication of penstock pipelines, crane plate, earth moving equipments and similar high strength applications, etc.
