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

  · Description: HJ250G is a smelting low manganese medium silicon and fluorine flux, which is light yellow to light green jade-like particles with a particle size of 2.0-0.45mm (10-40 mesh). Adopting DC power supply, the welding wire is connected to the positive electrode, the welding process has good performance, easy slag removal and beautiful appearance.

  · Use: With suitable welding wire, such as H08MnMoA, H08Mn2MoA, H08Mn2MoVA and other low-alloy high strength steels, such as 15MnV, 14MnMoV, 18MnMoNb, etc. With H08Mn2MoVA wire welding -70 ℃ low temperature steel 09Mn2V, it has better low temperature impact toughness.
