Maxfil-81R (Spl) is an all position low alloy steel (1.25% Cr-0.5% Mo) flux cored wire especially designed to achieve the desired all-weld metal mechanical properties even in as-weld condition. The wire gives smooth burning characteristics, low spatter, easy slag removal and radiographic quality weld metal. The wire is suitable for high temperature and pressure service conditions in steam pipes, boilers, etc.
Maxfil-81R (Spl) 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
