Details of HJ431
HJ431 is a kind of smelting-type,red brown to light yellow colored,glassy granulated flux with high manganese and silicon but low fluorine,mesh 8-14(2.5-1.5mm),8-40(2.5-0.45mm) and 14-40(1.5-0.45mm). Either alternating or direct current can be used and Welding wires must be connected with the positive electrode when direct current is used. The welding technology has good performance.

APPLICATIONS:
In combination with H08A, H08MnA AND H10Mn2 wires, this flux is suitable for welding of low carbon steels and some low alloy steel such as 16Mn and 15Mnv in producing of structures, boilers, ships, pressure vessels, ect. It can also be used for electroslag welding.

Cautions:
1.The oil soil,moisture,iron rust and other foreign substances must be removed from the surface before welding.
2.The flux must be baked under 300-400ºC for 2 hours.
