MAXFIL-31B (MDH)
AWS: SFA 5.29 E80T5G-C/M
EN ISO CODE: 17632-A T46 3 Z B M
Maxfil-31B (MDH) is a low alloy steel flux cored wire designed for welding of medium tensile steels structures subjected to dynamic loading. The wire gives good performance under CO2 and Argon-CO2 gas shielding with radiographic quality deposits. The weld metal has excellent crack resistance & toughness.
Maxfil-31B (MDH) is designed for single and multi-pass welding of similar composition steels, fine grained steels and equivalent grade steels like; Gr. F1 of SA-182 and SA-336, Gr. A of SA-204, Gr. T1/T1a/T1b of SA-209, Gr. WC1 of SA- 217, Gr. A of SA-302, Gr. P1 of SA-335, Class 1 of A grade of SA-533, etc. Suitable for fabrication of heavy machinery, steel plant equipments, horten spheres, etc.
