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:
It can be used for welding pressure-bearing equipment with 420N / mm2 tensile strength grade such as Q245R (20g, 20R) and other carbon steel structures with sintered pressure-type fluxers JQ.SJ301 and JQ.SJ501.
