Metallographic structure of Inconel 625 seamless pipe


625 is a face-centered cubic lattice structure. When kept at about 650°C for a long enough time, carbon particles and an unstable quaternary phase will precipitate and transform into a stable Ni3(Nb, Ti) orthorhombic lattice phase. The molybdenum and niobium components in the nickel-chromium matrix after solid solution strengthening will improve the mechanical properties of the material, but the plasticity will be reduced.


The corrosion resistance of Inconel 625 seamless pipe


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

Inconel 625 seamless pipe application range The application fields are


Soft annealed low-carbon alloy 625 is widely used in the chemical process industry. Its good corrosion resistance and high strength enable it to be used as a thinner structural component. Alloy 625 can be used where it is exposed to seawater and subjected to high mechanical stress. Typical application areas:

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

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

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

4. Used in the manufacture of equipment and components used in sour gas environments

5. Acetic acid and acetic anhydride reaction generator

6. Sulfuric acid condenser
