Low Alloy Metal Cored Wire
Maxfil-MC-81R is a gas shielded metal-cored wire designed for welding of steel with high temperature and pressure service conditions in steam pipes and boilers. The wire encompasses the deposition advantages of flux cored wire along with the high deposition efficiencies of a solid wire with both single and multi-layer applications. The deposited weld metal is virtually free from slag covering and thus reduces post-weld cleaning time. The wire burns with smooth arc and low spatter. Maxfil-MC-81R is suitable for 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. ASTM A 335-P11, FP2/FP11/FP12 of SA-369, Gr. 2/11/12 of SA-387, Gr.CP2/CP11/CP12 of SA-426.
