Submerged Arc Welding Flux HJ431
Flux HJ431, is a kind of high-Manganese oxide fused flux with glass granule red-brown to light yellow, grain size is about 8~40 mesh. The flux is good at welding and weldability. It is suitable for welding polarity with AC or DCEP.
Color: brownish-red to light yellow
Performance: easy to slag, smooth welding bead
Grain size: 8-40 meshes(2.5-0.45mm)
Material: Ore and alloy powder
Usage: welding ultralow carbon stainless steel
Applications:
For the combination with welding wire H08A, H08MnA, and H10Mn2, this fused flux is designed for welding low alloy high-strength steel ( such as 16Mn, Q345, Q3901, 15MnV steel, etc ) and the important steel structures, the fabrication of ships, boilers, and pressure vessels, etc.
