General Characteristics
Type: fluoride-alkaline type slag serial
Basicity: 1.6-1.8
Grain Size: 10-60 meshes(2.0-0.28mm)
Color: gray
Currency: AC/DC(wire to be connected to the positive electrode when using DC)
Features:
*stable burning arc, easy slag removal and smooth bead with head appearance.
*all weld metal shows excellent toughness at low temperatures with low diffusion of hydrogen, fine cold and heat crack resistance.
Applications
*suitable for welding low alloy steels for important products, such as ships, boilers, pressure vessels, pipelines and so on.
*suitable for multiple-wire submerged arc welding, especially for butt welding of large diameter vessel with one-pass on both sides.

Notes
1 Fluxes to be baked for two hours at 300-350¡æ before using;
2 It is better to use D/C;
3 Removal of rust, oil, dirt, water, impurities etc in welding-areas.
