BC-D212
D212 is a titanium-calcium coating overlay electrode. It can be used for both AC and DC, the arc is stable during surfacing welding, and the slag removal is easy.
BC-D256
D256 is a low-hydrogen potassium type coating overlay electrode.
BC-D507
D507 is a low-hydrogen sodium type coating overlay electrode.
BC- D507Mo
D507Mo is a 12Cr13 valve surfacing electrode with low hydrogen sodium type coating. The surfacing metal is 12Cr13 semi-ferritic high chromium steel. The surfacing layer has air quenching characteristics, and the surfacing metal has high medium temperature hardness, good thermal stability, and erosion resistance. When used in conjunction with D557 electrode, it can obtain good anti-abrasion performance, and adopts DC reverse connection.
BC-D668
D668 is a graphite-type coating overlay electrode. It can be used for both AC and DC, and has red hardness.
BC-D707
D707 is a low-hydrogen sodium type coating, carbon steel core surfacing electrode.
