H08A
Description:
Low-manganese low-silicon type wire, with high manganese, silicon flux matching, the base metal is not sensitive to rust, weld forming and slag removal performance is the largest amount of domestic submerged arc welding wire. 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.
