Inconel 625

Characteristics of Inconel 625

1. It has excellent corrosion resistance against various corrosive media in oxidizing and reducing environments.
2. Excellent resistance to pitting corrosion and crevice corrosion, and will not produce stress corrosion cracking caused by chloride
3. Excellent resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and mixed acids of sulfuric acid and hydrochloric acid, etc.
4. Excellent resistance to corrosion by various inorganic acid mixed solutions
5. When the temperature reaches 40°C, it can show good corrosion resistance in hydrochloric acid solutions of various concentrations.
6. Good processability and weldability, no post-weld cracking sensitivity
7. Manufacturing certification of pressure vessels with wall temperature between -196~450℃
8. Certified by the NACE standard of the American Society of Corrosion Engineers (MR-01-75) to meet the highest standard level VII for use in sour gas environments.

Alloy 625 shows excellent corrosion resistance in many media. Excellent resistance to pitting, crevice corrosion, intergranular corrosion and erosion in chloride media. It has good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid, etc. It also has resistance to alkali and organic acid corrosion in oxidizing and reducing environments. Effective resistance to chloride ion reduction stress corrosion cracking. It produces almost no corrosion in seawater and industrial gas environments, and has high corrosion resistance to seawater and salt solutions, even at high temperatures. No sensitivity during welding. Resistant to carbonization and oxidation in static or cyclic environments, and resistant to corrosion by chlorine-containing gases

Low carbon alloy 625 after soft annealing is widely used in the chemical process industry. Its good corrosion resistance and high strength enable it to be used as thin structural components. Alloy 625 can be used in applications where it is exposed to seawater and is subject to high mechanical stress. Typical application areas:
1. Components of organic chemical processes containing chlorides, especially where acidic chloride catalysts are used
2. Digesters and bleaching tanks for manufacturing pulp and paper industry
3. Absorption tower, reheater, flue gas inlet baffle, fan (humidity), agitator, guide plate and flue in the flue gas desulfurization system
4. For manufacturing equipment and components used in sour gas environments
5. Acetic acid and acetic anhydride reaction generator
6. Sulfuric acid condenser
