Hastelloy C-276 can be used in various chemical processes containing oxidizing and reducing substances, and its high chromium content makes it resistant to a variety of corrosion. The addition of tungsten further improves its corrosion resistance, making it one of the few materials capable of resisting media such as chlorine, hypochlorous acid and chlorine dioxide. In addition, Hastelloy C-276 has significant corrosion resistance to high-concentration chloride salt solutions (such as ferric chloride and copper chloride).
Supporting welding materials: Welding materials compatible with Hastelloy C-276 include ERNICRMO-4 welding wire and ENICRMO-4 welding rod.
Applications of Hastelloy C-276
Hastelloy C-276 is widely used in the chemical and petrochemical industries and is particularly suitable for the following situations:
It is used in components and catalytic systems that are in contact with chloride-containing organic matter, especially in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid) and seawater corrosion environments.
Pulp and paper industry, including scrubbers, reheaters, moisture fans, etc. in bleaching vessels and FGD systems.
Equipment and components operating in sour gas environments.
Reactor for acetic acid and acidic products.
Sulfuric acid condenser.
Sub-use diphenyl isocyanate (MDI) production and impure phosphoric acid production and processing.
In summary, Hastelloy C-276 is an ideal material widely used in industrial applications dealing with corrosive chemicals due to its excellent corrosion resistance and stability under a variety of extreme conditions.
