Low Alloy Steel Wire

MAXFIL- 44B

AWS: SFA 5.29 E100T5-D2C

EN ISO CODE:

Maxfil-44B is a low alloy steel flux cored wire designed for welding of high strength fine grained quenched & tempered steels to meet good sub-zero impact resistance property. 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-44B is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; SA-455M, Gr.60, Gr.65 steels of SA-515M, Class 1 of A, B, C, D grades of SA-533M. This wire is used for fabrication of crane plate, earth moving equipments, penstock pipelines and similar high strength applications, etc.
