· Compliance: GB / T5293-1999, F4A2-H08A AWS A5.17, F6A0-EL12

· Description: HJ431 is a smelting type high manganese high silicon low fluorine flux. It is brown red 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: It can be used with H08A, H08MnA, H10MnSi and other welding wires to weld low carbon steel and certain low alloy steels, such as 16Mn, 15MnV and other structures, such as boilers, ships, pressure vessels, etc., and can also be used for electroslag welding and copper welding.
