Exaton Ni60 Overlay

Exaton Ni60 Overlay

The welding wire of Exaton Ni60 Overlay is especially suitable for overlay welding on non- and low alloyed steels using either hot wire TIG and mechanized TIG or MIG welding. It can also be used for dissimilar joining of stainless steels to nickel alloys, such as 6Mo-steels to UNS N06625 (2.4856) and corresponding grades. The weld chemistry is very corrosion resistant in oxidizing, aqueous and high temperature environments. Applications for Exaton Ni60 Overlay are found in Oil and gas application such as valves, tubes and flanges. Other applications are cryogenics, components subject to high temperature service up to 980°C (1800°F) such as aircraft ducting, engine exhaust systems, power boilers and recovery boilers and a diversity of seawater applications. The combination of strength and corrosion resistance over a wide range of temperatures is utilized in reaction vessels, line pipe distillation columns and heat exchangers.
