LJ-HJ350
Jinan Jincai Welding Material Co. , Ltd.

Conforming to::GB/T12470   S49S2MS-SU34

Equivalent to:  AWS F7A0-EH14    JIS YSF-W41

Description: HJ350 is defined as fused type fluxes medium-manganese, medium-silicate and medium fluorine elements, color in brown to high yellow, with vitreous granules 8-40 meshes in size. Fluxes are suitable for use both AC and D.C. When applying D.C, filler-wire will be connected to electrode positive (EP). Fluxes have good welding technological behavior.
Field of application: Fluxes match proper filler-wire (i. e SU26、SU34、SUM3 etc) of which may be use for welding of low-alloyed steel (i. e. 16Mn、15MnVN、15MnV etc) important structures for example: ships, boilers, pressure vessels etc. As required by fine-granule fluxes, they can be used for SAW with filler-wire to serve thin-plating weld.

Remarks:
     1.Before welding, fluxes need to be baked for two(2)hours at around 300-350℃.
    2.Removal of rust, oil, dirt, water, impurities etc in welding-areas.
