Used for joining & cladding similar grades of copper-nickel alloys, with up to 30% nickel content. Shipbuilding, food industry, desalinization plants, refrigerators, heat exchanger, pumps, valves, pipelines, etc.
Ni-Cr-Fe basic coated stick electrode for heat resistance
UTS: 55-60 kgf/mm2
This is a versatile electrode for welding of nickel, inconel, monel, nickel-chromium-iron alloys. Weld deposits are similar to ENiCrFe3. HK alloys, steel, stainless steel and heat resisting steels. Also for welding dissimilar metals such as carbon steels, stainless steels, nickel, nickel alloys to each other. For use on equipment and components made of pure nickel, for fabrication of corrosion resistant tanks and containers, heat exchangers, furnace components, boilers, fittings, anchors, mill trunnions, symmetry gears, etc. Very good for repair of cracks in kiln tyres.
