HF-SJ301 Classifications Standard GB F4A2-H08A Accord with AWS F7A0-EL8 General Characteristics HF-SJ301 is designed as a Si-Ca neutral agglomerated flux(B.I.: 1.0). They are small grey balls with grain sizes 2.0-0.28mm (10-60 meshes). It can be used with AC/DC and large current. Its unique features include stable burning arc, easy slag removal and smooth bead appearance. It forms short slag without the phenomenon of slag-flow. Applications Combination with wires, such as H08A(EL8), H10Mn2(EH14), this flux is suitable for welding structures, boilers and piplines, etc. Typical Chemical Compositions of the Flux (%) SiO2+TiO2 CaO+MgO Al2O3+MnO CaF2 Others 35-45 20-35 20-35 5-15 10 Mechanical Properties of all Weld Metal Test Item ?s Mpa ?b Mpa δ5 % AKV(J) -20℃ Guaranteed Value ≥330 415-550 ≥22 ≥27 Test Value 400 518 33 100, 90, 130 Notes 1.
