Used for TIG, MIG and SAW welding of base materials such as ASTM B163, B166, B167 and B168 alloys which have UNS Number N06600. Suitable for applications ranging from cryogenic to high temperatures making this alloy on of the most used in the nickel family. This filler metal can also be used for dissimilar welding applications between various nickel alloys and stainless or carbon steels, as well as for overlay. ERNiCr-3 is ideal for welding in desalination plants because it is formulated to resist pitting corrosion and stress-corrosion cracking in chloride containing environments.
