Low Alloy Steel Wire

MAXFIL-34B (MDH)

AWS: SFA 5.29 E81T5G-M

EN ISO CODE:

Maxfil-34B (MDH) is a low alloy steel flux cored wire designed for welding of medium tensile (containing Nickel, Molybdenum) steels structures subjected to dynamic loading. The wire gives good performance under Argon-CO2 gas shielding with radiographic quality deposits. Presence of Nickel & Molybdenum in the weld metal, imparts an excellent crack resistance & toughness properties.

Maxfil-34B (MDH) is suitable 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 & structures, high strength fabricated structures etc.
