Product Description

Submerged arc welding fluxes
welding flux Description:      
  1.SJ501 is a kind of aluminum-titanium-type sintered flux.
  2.Color: deep gray to dark brown.
  4.Grain size:10-40 (2.0-0.45mm) meshes.
  5.Either alternating or direct current can be used.
 6.Performance:high rust resistance, easy slag dropping, smooth welding bead, and good welding technology.
  1.The welding flux is for low carbon, low alloy, and pressure vessel steels(applied to various welding wires such as H08A, H08MnA, H08MnMo and H10MnSi).
  2.Fit for fast welding of thin steel sheet (gas steel tanks and membrane water-cooled wall) in boiler factory.
