1. Product Description:
Welding flux HJ431 is a kind of high-Manganese oxide and -SiO2 -CaF2 smelt flux. It is a kind of granule red brown to light yellow color,
The size is about 2.5-0.45mm (8-40 mesh) and 1.5mm-0.18mm (14-80 mesh),
When used on AC or DC(+). It is good at welding and weld-ability.
2. APPLICATION:
In combination with H08A,H08MnA, H10Mn2, welding wire, this fused flux is suitable for welding low alloy high-strength steel ( such as 16Mn, 15MnVN ),welding the important structures, the fabrication of ships, boilers and pressure vessels etc.
