Low Hydrogen Electrodes

APLHA 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 bases metal is not necessary. given radiography welds excellent ductility and notch toughness down to minus 300c are some of special characteristics of alpha 7016.
