Corrosion Resistance
C-276 is a nickel-chromium-molybdenum-tungsten alloy with very low carbon and silicon content, recognized for its outstanding corrosion resistance in both oxidizing and reducing environments. Key features:
- Excellent resistance to a wide range of corrosive media, including acids, chlorides, and mixed chemical environments.
- Superior resistance to pitting, crevice corrosion, and stress corrosion cracking.
- High molybdenum and chromium contents provide exceptional resistance to chloride-induced attack, while tungsten further enhances overall corrosion performance.
C-276 is one of the few alloys capable of resisting wet chlorine gas, hypochlorite, and chlorine dioxide solutions. It also demonstrates excellent resistance to highly concentrated chloride solutions, such as ferric and cupric chlorides. In addition, the alloy performs exceptionally well in sulfuric acid over a broad concentration range and is suitable for service in hot, concentrated sulfuric acid environments.
