ENI 422 (Cardboard)

Basic coated electrode with Ni-Cr-Fe type nickel base deposit. Used for repairing and joining of nickel alloys, 5 – 9% Nickel steels, cryogenic stainless steels down to -196°C, Incoloy 800 and other high temperature steels. Provides a weld metal which has a operating temperatures from -196°C to 800°C. Used for joining dissimilar materials as stainless steels/low alloyed steels, stainless steels/Nickel alloys, buffering of difficult to weld steels. Weld metal deposit is insensitive to cracks, has very good resistance to acids, salts and alkaline solutions, molten salt (e.g. cyanide) in oxidizing and carburization atmospheres (avoid a sulphurous atmosphere). Generally used for welding on oven parts, burners, heat treatment equipment, cement works, moulds, transport and storage tanks of liquid gas. Has a wide range of application in chemical industry, petrochemical industry, glassworks, civil engineering, repairing and maintenance workshops.
