ERNiCr-3

Description
ERNiCr-3 is suitable for applications ranging from cryogenic to high temperatures making this alloy one of the most used in the nickel family. Weld metal deposited has high strength and good corrosion resistance, including oxidation resistance and creep-rupture strength ar elevated temperatures. It can equivalent to: Oxford Alloy 82 FM82 Techalloy 606.

Applications
ERNiCr-3 for 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 one of the most used in the nickel family. Also be used for dissimilar welding applications between various nickel alloys and stainless or carbon steels, as well as for overlay.
