MAXFIL- 31B (SPL)

AWS: SFA 5.20 E71T-5M EN ISO CODE: 17632-B T493T1-1MA-K

Maxfil-31B (Spl) is a mild steel flux cored wire suitable for all position welding with Argon-CO2 gas shielding. The wire gives smooth burning characteristics, low spatter and easy slag removal. Filler contour is flat to slightly convex with equal leg lengths and uniform sidewall fusion. The deposited weld metal is of radiographic quality. The deposited weld metal contains very low diffusible hydrogen (<5ml/100gms of weld metal).

Maxfil-31B (Spl) is designed for single and multi-pass welding of low and medium carbon steels grades like; C, D, E grades of SA-414, Gr.55, Gr.60 steels of SA-516 and equivalent grade steels, etc.
