Name of Item:  High Manganese-oxide Fused flux LHHJ431 

Executed Standards:  AWS A5.17 F6AZ-EL12; JIS YSF42-W11 

Specification of Fused Flux：
Flux LHHJ431, it is a kind of high-Manganese oxide fused flux with glass granule red-brown to light yellow, grain

size of 2.5mm~0.45mm (8~40 mesh). The flux is good at welding and weld-ability.  It is suitable for the welding

polarity with AC or DCEP.

Application of Flux：
For the combination with welding wire H08A, H08MnA, H10Mn2, this fused flux is designed for welding low alloy high-

strength steel ( such as 16Mn, 15MnV steel etc )
and the important steel structures, the fabrication of ships, boilers and pressure vessels etc.
