Exaton 20.25.5.LCu (ESW)

Exaton 20.25.5.LCu is a copper alloyed chromium-nickel-molybdenum strip electrode used for electro-slag welding (ESW) or submerged arc welding (SAW) to deposit a second and third layer corrosion resistant alloy of 20%Cr/25%Ni/5%Mo/Cu composition on carbon- and low alloyed steels. The buffer layer can be deposited using Exaton 20.25.5.LCu, but also strip electrodes such as 21.13.3.L or 22.11.L can be used. Exaton 20.25.5.LCu is used for weld surfacing of components in the chemical, petrochemical, marine industry where corrosion resistance equal to UNS N08904 is required. Typical components are heat exchangers, pressure vessels, shafts etc.
