Hastelloy C276 alloy's resistance to general and localized corrosion (particularly pitting, crevice corrosion, and stress corrosion cracking) in extremely harsh environments, along with its excellent machinability and weldability, makes it a preferred material for solving complex corrosion problems. It is a reliable safeguard for critical equipment and components in chemical processing, environmental protection, energy, and other fields, significantly extending equipment life, reducing maintenance downtime, and improving production safety and economic efficiency.
Excellent general corrosion resistance:
Performs well in a wide range of acids, alkalis, and salts, including sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, and organic acids.
Strong resistance to wet chlorine, hypochlorite, and chlorine dioxide solutions.
Excellent localized corrosion resistance:
Strong resistance to pitting and crevice corrosion: Thanks to its high molybdenum and chromium content.
Excellent resistance to stress corrosion cracking (SCC): Particularly in chloride- and sulfide-containing environments.
Excellent Oxidation Resistance:
Stable performance in moderately high-temperature oxidizing atmospheres (such as air and sulfur-containing fumes).
Excellent Reduction Resistance:
Performs far beyond stainless steel and many other nickel-based alloys in reducing acids (such as sulfuric and hydrochloric acids).
