MAXFIL-81R

AWS: SFA 5.29 E81T1-B2M

EN ISO CODE: 17632-B T55ZT1-1MP-G

Maxfil-81R is an all position low alloy steel flux cored wire designed for welding of 1.25% Cr-0.5% Mo steel with high temperature and pressure service conditions in steam pipes and boilers. The slag coverage is complete and easy to remove. This wire burns with low spatter & minimal fumes with radiographic quality deposits.

Maxfil-81R is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; Gr. F2/F11/F12 of SA-182, Gr. T11 of SA-199, Gr. T2/T11/T12 of SA-213,Gr.WC6 of SA-217, Gr. P2/P11/P12 of SA-335, Gr. FP2/FP11/FP12 of SA-369, Gr. 2/11/12 of SA-387, Gr.CP2/CP11/CP12 of SA-426.
