Hastelloy C-2000 Features:

Hastelloy C-2000 Hastelloy C-2000 is an optimized alloy developed to expand the application range of materials. It is resistant to sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, organic acids, chlorides, alkali metals, pitting corrosion, crevice corrosion, and stress corrosion. It has excellent corrosion resistance in media and working conditions such as cracking, and is the most comprehensive high-temperature corrosion-resistant alloy. Excellent resistance to uniform corrosion in both oxidizing and reducing environments. Compared with C-276 alloy, it has excellent resistance to stress corrosion cracking and better resistance to local corrosion. Hastelloy C-2000 Hastelloy has been widely used in the chemical and petrochemical fields, such as in components and catalytic systems that come into contact with chloride-containing organic matter. This material is especially suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid), and seawater corrosion environments.

Other application areas:

1. Pulp and paper industry, such as digestion and bleaching vessels; scrubbers, reheaters, moisture fans, etc. in FGD systems.

2. Equipment and components operating in acidic gas environments; reactors for acetic acid and acidic products; sulfuric acid condensers; methylene diphenyl isocyanate (MD1); production and processing of impure phosphoric acid.

3. Reactors, heat exchangers, towers, pipelines in the chemical industry, reactors and dryers in the pharmaceutical industry, and flue gas desulfurization system components.
