Applications of Hastelloy C276 Flanges

Corrosion-Resistant Applications

Hastelloy C276 Flanges are corrosion-resistant alloys that resist various chemical process environments. They also possess superior strength and toughness at elevated temperatures, making them suitable for high-temperature applications such as heat exchangers and flanges. The chromium in these alloys resists oxidation, and the molybdenum resists localized corrosion such as pitting. Their nickel content makes them highly resistant to stress-corrosion cracking and crevice corrosion, while the addition of tungsten helps prevent sulfide stress corrosion cracking. With its low carbon component, this alloy is particularly well suited for applications where local or intergranular corrosion is a concern due to weldability characteristics.


Seawater Applications

Hastelloy C276 flanges are a nickel-molybdenum alloy created to provide excellent corrosion resistance in various industrial, chemical, and marine applications. The combination of molybdenum and chromium gives it exceptional strength, making it suitable for high-pressure applications. Furthermore, its superior corrosion resistance in seawater makes it an ideal choice for components exposed to seawater, such as flanges. Hastelloy C276 is also resistant to chloride-induced stress corrosion cracking (SCC). This is due to chromium, which helps form a protective oxide film on the exposed surface when exposed to air or salt water. It has outstanding thermal stability and superior fabricability and weldability properties, making it a preferred material for pipe fittings like flanges used in several industries such as oil refineries, pharmaceuticals industry, chemical processing plants etc.


High-Temperature Applications

Hastelloy C276 flanges are one of the most corrosion-resistant metal alloys for high-temperature applications. These flanges have superior oxidation and sulfide stress cracking resistance and can withstand temperatures up to 1350°C without losing mechanical properties. They also remain stable in various corrosive media such as seawater, hydrochloric acid, sulfuric acid and acetic acid. In conclusion, Hastelloy C276 flanges provide excellent performance at elevated temperatures, making them an ideal choice for many industries, including automotive, aerospace and power generation.


Petrochemical Industry Applications

Hastelloy C276 flanges are corrosion-resistant components used in various Petrochemical industry applications. This special alloy has excellent resistance to stress corrosion cracking and crevice corrosion, making it an ideal choice for many petrochemical applications such as petrochemical tanks, chemical process equipment, pollution control systems, and heat exchangers. Its high molybdenum content offers superior strength and makes it resistant to various acids that commonly corrode other metals. In addition, its chromium content provides further protection from oxidation at higher temperatures. Moreover, the low carbon content helps prevent graphitization in extreme heat conditions, while its nickel-molybdenum-chromium (NiMoCr) combination also contributes to good weldability and formability characteristics. Hastelloy C276 flanges in the Petrochemical industry are essential for ensuring efficient production operations with minimal maintenance costs due to their reliability and long service life over a wide range of operating conditions.


Power Generation Applications

Hastelloy C276 flanges are an excellent choice for power generation applications. These flanges offer high-temperature strength, excellent resistance to oxidation and corrosion, pitting resistivity, and great fabricability. This makes them suitable for use in the most demanding power generation environments, such as steam turbines, condensers, pumps, piping systems and other components in nuclear plants. Additionally, Hastelloy C276 is easy to machine and weld, making the components faster without sacrificing quality or integrity. In short, Hastelloy C276 flanges are ideal for the highly specialized needs of power generation applications due to their superior performance and durability.


Conclusion

Hastelloy C276 has become a trusted material for flange applications thanks to its excellent corrosion, heat, and stress resistance. It’s widely used in various industries, including chemical processing plants, petrochemical industries, power generation, marine environments, etc. Hastelloy C276 flanges ensure safety, performance, and reliability in severe environments.
