DESCRIPTION

AND

APPLICATION

 

HEAVY COATED LOW HYDROGEN, IRON POWDER TYPE ELECTRODE. The weld deposit contains 3.5 Nickel. The electrode is designed for welding of nickel alloy steel. It gives very good toughness and resistance to embritting effects down to -100C. Gives radiographic quality weld deposit. Deposition efficiency 115% (approx.).

Recommended for welding of 3 3.75% Nickel steels. Fabrication of parts subject to low temperature service, Refinery pressure vessels and valves. ASTM A333-Grade 3 pipe etc.
