MAXFIL- 37R

AWS: SFA 5.29 E81T1-Ni1C

EN ISO CODE: 17632-B T553T1-1CA N2

Maxfil-37R 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. The wire gives optimum performance under CO2 shielding and deposits radiographic quality weld metal. The weld has excellent bead appearance and easy slag removal. The wire sets low diffusible hydrogen content (<4ml/100gm) in the weld metal.

Maxfil-37R 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.
