ERNiCr-3 / Inconel 82 / Alloy 82 Nickel-Chromium Welding Wire | AWS A5.14 ERNiCr-3 Filler Metal for Corrosion & Heat Resistant Welding
Product Overview
ERNiCr-3 welding wire (Inconel 82 type) is a nickel-chromium alloy filler metal designed for welding Inconel 600, Incoloy 800/825, and dissimilar joints between nickel alloys and stainless steels.
It offers excellent resistance to oxidation, corrosion, and cracking in high-temperature and aggressive environments, making it ideal for chemical processing, power generation, marine, and nuclear industries.
Key Features
-
High-Temperature Strength: Maintains mechanical stability and oxidation resistance up to 900 °C.
-
Excellent Corrosion Resistance: Performs well in oxidizing and reducing environments, acids, and chloride atmospheres.
-
Dissimilar Metal Welding: Suitable for joining nickel alloys to stainless steels or carbon steels.
-
Smooth Welding Performance: Stable arc transfer, low spatter, and smooth bead appearance.
-
Clean and Ductile Weld Deposit: Produces crack-free, porosity-free welds with strong mechanical integrity.
