Characteristics
Exceptional corrosion resistance in both oxidizing and reducing environments, making it highly versatile for various chemical processing applications.
Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, even in severe chloride-rich conditions.
Metallurgical Structure
Alloy C-276 has a face-centered cubic (FCC) lattice structure, contributing to its excellent mechanical properties and corrosion resistance.
Corrosion Resistance
Alloy C-276 is well-suited for a wide range of applications in the chemical processing industry, as it can withstand both oxidizing and reducing media.
High molybdenum and chromium content provide excellent resistance to chloride-induced corrosion.
Tungsten enhances overall corrosion resistance, making it superior in highly aggressive environments.
Alloy C-276 is one of the few materials that can resist most chlorine-containing compounds, including chlorine gas, hypochlorite, and chlorine dioxide.
It exhibits superior resistance to concentrated chloride solutions, such as ferric chloride (FeCl₃) and cupric chloride (CuCl₂).
Applications
Due to its superior corrosion resistance, Alloy C-276 is widely used in the chemical and petrochemical industries, particularly in chloride-rich and catalytic environments. It is especially suitable for:
High-temperature environments with exposure to impure inorganic and organic acids (e.g., formic acid, acetic acid).
Marine and seawater applications, where corrosion resistance is crucial.
Other Application Fields
Pulp and Paper Industry – Used in digesters and bleaching equipment.
Flue Gas Desulfurization (FGD) Systems – Key components include absorption towers, reheaters, and fans.
Acidic Gas Environments – Suitable for equipment and components exposed to acid gases.
Acetic Acid and Anhydride Production – Applied in reaction vessels.
Sulfuric Acid Cooling Systems – Resistant to harsh acidic conditions.
MDI (Methylene Diphenyl Diisocyanate) Production.
Phosphoric Acid Manufacturing and Processing, especially for handling impure phosphoric acid.
