· Compliance: GB / T12470-2003, F48A2-H10Mn2 AWS A5.23, F7A0-EH14

· Description: HJ350 is a smelting type manganese, silicon, and fluorine flux. It is brown to light yellow glass-like particles with a particle size of 2.5-0.45mm (8-40 mesh). It can be used for both AC and DC. The welding wire is connected to the positive electrode during DC welding. The welding process has good performance, easy slag removal and beautiful appearance.

· Application: With suitable welding wire, it can weld low alloy steel, such as 16Mn, 15MnV, 15MnVN and other important structures, such as ships, boilers, high-pressure vessels, etc.
