Low Alloy Steel Wire

MAXFIL- 81W

AWS: SFA 5.29 E81T1-W2C EN ISO CODE: 17632-B T553T1-1CA NCC1

Maxfil-81W is an all position low alloy steel flux cored wire designed for welding of high strength weatherresistant grade steels. The wire gives optimum performance with 100% CO2 shielding and characterized with smooth metal transfer, uniform welding even on vertical-up stringer beads and easy slag removal. In fillet welds, the bead contour is flat to slightly convex with equal leg lengths and uniform sidewall wetting. Weld metal is free from porosity and conforms to X-ray soundness.

Maxfil-81W is designed for single and multi-pass welding of weather resistant steels - Corten steels grade A/B, Class 1 steels of type A of SA-533, etc.
