Specification: AWS A5.17-97 ASME SFA 5.17Classification: F7AZ-EL12
LJ-HJ431 is defined as fused type fluxes with high-manganese high silicate and low fluorine elements. Color in brown to light yellow with vitreous granules 8-40 meshes in size. Fluxes are suitable for use with both AC & DC. When applying D.C. filler wire will be connected to electrode positive (EP). Fluxes have good welding technology behavior.
