JH-350 Welding Flux

JH-350 is a type of fused flux with medium Mn, medium Si and medium F content, brownish red to light yellow glassy grains in appearance. Its grain size is 8-40 meshes or 14-80 meshes. JH-350 is suitable for use with AC Or DC Power, filler wires connect with positive electrode while in DC. with excellent technological properties of welding

Combining with appropriate wires, JH-350 is used for welding low alloy structures (16Mn, 15Mn v N,15MnV and other important structures) in ships ,boilers, high pressure vessels and other applications. Fine-grained flux is used for fine-wire SAW and welding thin-plate structures.
