HF-SJ101 Classifications Standard GB F4A4-H08MnA F5A4-H10Mn2 Accord with AWS F7A4-EH14 General Characteristics HF-SJ101 is a bonded high basic flux (B.I.: 1.8) with ball form gray granule of 10-60 meshes(2.0-0.28mm) in size. It can be used with AC/DC or even large current. Its unique features include stable burning arc, easy slag removal and smooth bead with head appearance. The all weld metal shows excellent toughness at low temperatures. Applications Matching with wires H08MnA(EM12), H10Mn2(EH14), H08MnMoA, H08Mn2MoA, etc, SJ101 is suitable for welding low alloy steels for important products, such as ships, boilers, pressure vessels, pipelines and so on. It is also suitable for multiple-wire submerged arc welding, especially for butt welding of large diameter vessel with one-pass on both sides.
