MAXFIL MC-42B

AWS: SFA 5.36M E11T15- M21A5-K4

Maxfil MC-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 -50oC. The wire gives optimum performance under Ar + CO shielding and deposits radiographic quality weld metal. The deposited weld 2 metal is virtually free from slag covering and thus reduces post welding cleaning time.

Maxfil MC-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.
