Low alloy copper-coated solid wire designed for welding low alloy steels with 3,5% Ni content, fine grained for low temperature applications. It is used in petrochemical industry where it finds applications in construction of cryogenic plant and associated pipework, in the manufacture, storage and distribution of volatile liquids and liquefied gases, when operating at temperatures to -80°C. To be used under the shield of Ar+O2.
