Name: Fused submerged arc welding flux HJ250G
AWS: AWS A5.17/5.23 F7A0-EH14
SAW wires: EH14, EA2, EA3
Power supply: DC (DCEP)
Grain size: 10-40 mesh (0.45-2.0mm)
Category: submerged arc welding of low-alloy high strength steel, cryogenic steel
Description: HJ250G is fused flux with low manganese, medium silicate and medium fluoride content. It is light yellow, light green glass-like granule. It is suitable for use with DC current, and please connect wire with positive electrode. The flux is featured with excellent welding performance, easy slag peeling, smooth weld pass. Welding flux HJ250G could be used to weld low alloy high strength steel with SAW wires like EA2, EA3, H08Mn2MoVA. It is also used to weld cryogenic steel 09Mn2V with SAW wire H08Mn2MoVA.
Package: damp-proof packing, 25kg/bag
Certification: ISO
