This basic electrode is suitable for joining and surfacing of nickel-copper alloys and of nickel-copper-clad steels. It also suited for joining different materials, such as steel to copper and copper alloys, steel to nickel-copper alloys. Excellent corrosion resistance to chloride induced stress corrosion cracking and a wide range of marine and chemical requirements. These materials are employed in high-grade apparatus construction, primarily for the chemical and petrochemical industries. A special application field is the fabrication of seawater evaporation plants and marine equipment.
