Low Hydrogen Electrodes


Low Hydrogen Electrodes

Our company is a well-renowned Manufacturer and Supplier of Low Hydrogen Electrodes. The ALPHA 8018 W Low Hydrogen Electrodes are iron powder basic type electrode for all position welding. They show high resistibility to atmospheric corrosion. The Basic Coated Low Hydrogen Electrodes contain Cu, Ni and Cr, Crack resistibility and mechanical properties. Smooth and regular fusion of Low Hydrogen Electrodes gives uniform bead shape. Welds are of radiographic quality.

Alpha 7016 Coding :- IS 814 - 2004 : Eb5424h3x, Aws / A5.1 : E7016

Alpha 7016 is a basic coated low hydrogen electrode specially designed for welding of medium and high tensile structural steel joining and surfacing of high strength steels such as carbon steel up to 0.40% C. Manganese steel up to 2.0% Mn, silicon steel up to 0.5% SI and other heat treated steels where matching of base metal is not necessary, gives radiography welds excellent ductility and notch toughness down to minus 300oC are some of special characteristics of Alpha 7016.
