LJ-HJ431
Jinan Jincai Welding Material Co. , Ltd.

Conforming to:GB/T53293    S43A0UMS-SU08A  

Equivalent to: AWS F6AZ-EL12

JIS YSF42-W11

Description: HJ431 is defined as fused type fluxes with high-manganese high silicate and low fluorine elements. Color in brown to light yellow with vitreous granules 8-40 meshes in size. Fluxes are suitable for use with both AC & DC. When applying D.C. filler wire will be connected to electrode positive (EP). Fluxes have good welding technology behavior.

Field of application: Fluxes match filler wire (i. e. SU08A、SU26,and SU34 etc.) of which may be used for welding of mild-steel low alloyed steel (16Mn, 15MnV) structures for examples, boilers, ships, pressure vessels and Electro-slag welds as well as copper welds.

Remarks:
    1.Before welding, fluxes need to be baked for two(2)hours at around 250℃.
    2.Removal of rust, oil, dirt, water, impurities etc in welding-areas.
