Inconel625 application areas

The softened and annealed low carbon alloy 625 is widely used in the chemical process industry, and its better corrosion resistance and high strength enable it to be used as a thinner structural component. Alloy 625 can be used in applications exposed to seawater and subject to high mechanical stress. Typical application areas:

1. Components of organic chemical processes containing chlorides, especially where acid chloride catalysts are used

2. Digesters and bleaching tanks for the pulp and paper industry

3. Absorption tower, reheater, flue gas inlet baffle, fan (humid), agitator, deflector and flue in flue gas desulfurization system

4. For the manufacture of equipment and components for use in sour gas environments

5. Acetic acid and acetic anhydride reaction generator

6. Sulfuric acid condenser
