Hastelloy C-276: Properties and Applications
Date:2024-05-17 17:19:10View:157Tags:Nickel Alloy Supplier

Hastelloy C-276 has excellent corrosion resistance to most corrosive media in both oxidized and reduced states, which makes it perform well in a variety of environments. In addition, the alloy offers excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking, making it an ideal choice in many areas.

 

Metallographic structure of Hastelloy C-276
Hastelloy C-276 has a face-centered cubic lattice structure, which gives it higher strength and good ductility. In addition, this alloy also has good welding and processing properties, which facilitates its application in various engineering fields.

 

Corrosion Resistance of Hastelloy C-276
Hastelloy C-276 alloy is suitable for use in various chemical process industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes it resistant to corrosion by chloride ions, while the addition of tungsten further improves its corrosion resistance. C276 is one of the only materials that can withstand corrosion from moisture, hypochlorite and chlorine dioxide solutions. The alloy also has significant corrosion resistance to highly concentrated chloride salt solutions, such as ferric chloride and copper chloride.

 

Application range of Hastelloy C-276
Due to its excellent corrosion resistance, Hastelloy C-276 is widely used in many fields. In the chemical and petrochemical fields, C276 alloy is widely used in components and catalytic systems that come into contact with chloride-containing organic matter. This material is particularly suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as sulfuric acid and nitric acid), and seawater corrosive environments. In the pulp and paper industry, Hastelloy C-276 is used in the manufacture of equipment such as digestion and bleaching vessels because of its ability to withstand acidic environments containing hypochlorite. In addition, in flue gas desulfurization (FGD) systems, C276 alloy is also used in the manufacture of scrubbers, reheaters, wet steam fans and other equipment. These devices operate in sour gas environments and require excellent corrosion resistance. Hastelloy C-276 alloy is also widely used in equipment such as methylene dibenzoate (MDI) and acid condensers in the production of impure acids. The acidic environments involved in these applications place extremely high demands on the material's corrosion resistance, and Hastelloy C-276 is ideal for solving these problems.

 

As a high-performance nickel-based alloy, Hastelloy C-276 has attracted much attention due to its excellent corrosion resistance and wide range of applications. It plays an important role in chemical industry, petrochemical, pulp and paper, FGD systems and other fields. Understanding the characteristics, metallographic structure, corrosion resistance and application range of Hastelloy C-276 will help you better select and use this material to meet the needs of various harsh environments.
