Description:
Low-manganese low-silicon type wire, with high manganese, silicon flux match, the base metal is not sensitive to rust, weld bead forming and slag performance. Single, bipolar, AC, DC welding can be.
use:
301, 501 with a sintered flux, 420N / mm 2 high-speed welding and filled with weld tensile strength of the base metal levels can be.
