Low Alloy Steel Wire

MAXFIL- 37B

AWS: SFA 5.29 E80T5-Ni1C

EN ISO CODE: 17632-B T555T5-0CP N2

Maxfill-37B 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-37B is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; A/B grades of SA-203, A/B/C grades of SA-662, B/C grades of SA-737, N-A-XTRA-60/65, etc. This wire is used for heavy fabrication work subjected to dynamic loading, earth moving equipments, off-shore platforms and similar kind of applications, etc.
