HJ431 is a kind of fused glassy granulated flux, colored as red-brown to light-yellow,
high in manganese and silicon but low in fluoride. Either alternate or direct current
can be used. The welding performance is excellent.
When applied with welding wires such as H08A, H08MnA, H10Mn2 or H10MnSi, HJ431
can weld low-carbon steel and some low-alloy steel like 16Mn and 15MnV, as well as
ships, boilers and low-pressure vessels.
