HJ350 Melting Type Medium Manganese, Medium Silicon And Medium Fluorine Flux
HJ350 [Flux 350]: Conforms to GB12470-90 HJ402-H10Mn2 (AWS F6A0-EH14), HJ350 is a melting type medium manganese, medium silicon and medium fluorine flux, which is brown to light yellow glassy particles. The particle size is 2.5-0.45mm (8-40 mesh), etc. It can be used for both AC and DC. When DC welding, the welding wire is connected to the positive pole, with good welding process performance, easy slag removal and beautiful shape.
Uses: With appropriate welding wire, it can be used to weld low alloy steel (such as 16Mn, 15MnV, 15MnVN) and other important structures, such as ships, boilers, high-pressure vessels, etc. Fine-grained flux can be used for fine-wire submerged arc welding and welding of thin plate structures.
