Acid-resistant, Hastelloy 276 is a good corrosion-resistant material
C276 is face-centered cubic lattice structure.
V. Properties:
1. Excellent corrosion resistance to most corrosive media in oxidized and reduced states.
2. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking performance. c276 alloy is suitable for a variety of chemical process industries containing oxidizing and reducing media.
Higher molybdenum and chromium content makes the alloy resistant to chloride ions, and tungsten further improves its corrosion resistance.C276 is one of only a few materials that are resistant to corrosion by moist chlorine,
hypochlorite, and chlorine dioxide solutions, and the alloy has significant corrosion resistance to high concentrations of chlorinated salt solutions (e.g., ferric chloride and copper chloride).
Six, application areas:
C276 alloy in the chemical and petrochemical fields have been widely used, such as in contact with chlorinated organic components and catalytic systems. This material is particularly suitable for use in high temperature,
inorganic and organic acids mixed with impurities (such as formic and acetic acid), seawater corrosive environment.
Mainly used in the manufacture of the following types of equipment or parts:
1. Pulp and paper industry, such as boil-off and bleaching vessels:
2. Scrubber towers, re-heaters, and wet steam fans in FGD?systems:
3. Equipment and components operating in acidic gas environments;
4. Reactors for acetic acid and acidic products;
5.
5. Sulfuric acid condensers;
6. Methylenediphenyl isocyanate (MDI);
7. Production and processing of impure phosphoric acid .
