HJ257
Appearance:
Brown or black glassy particles
Granularity:
8-40 mesh
Product Introduction:
HJ257 is a melting low manganese medium silicon medium fluorine flux. It is a brown or black glassy particle with a grain size of 2.5-0.45mm(8-40 mesh). The DC power supply is adopted, the welding wire is connected to X, the welding process is good, the slag removal is easy, the forming is beautiful.
Purpose:
With appropriate welding wire, such as H08MnMoA, H08MnMo2A, H08Mn2MoVA and other low alloy high strength steel, such as 15MnV, 14MnMoV, 18MnMoNb and so on.
Welding wire tensile strength Yield strength elongation AKV (J)
H10Mn2 490-670 ≥390 ≥18 ≥27
Matters needing attention:
1. Before welding, electric X should be baked at 300-350ºC for 1.5-3 hours.
2. The impurities on the workpiece must be removed, such as rust, oil stains and moisture.
