Low Alloy Steel Wire

MAXFIL- 42B

AWS: SFA 5.29 E110T5-K4C

Maxfil-42B 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 -51°C. The wire gives optimum performance under CO2 shielding and deposits radiographic quality weld metal. The weld has excellent bead appearance and easy slag removal.

Maxfil-42B 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 crane plate, earth moving equipments and similar high strength applications, etc.
