ER70S-6 rods contain high levels of manganese and silicon for enhanced deoxidizing power. This rod is designed to provide porosity-free welding. The high silicon content improves weld metal fluidity, producing a smoother bead appearance and minimizing post-weld grinding. It is used for a wide range of general engineering and pipe fabrication applications, including construction work, tanks, truck bodies, agricultural tools, and pressure vessel piping.
