Introduction to Nickel-Based Alloy 625:
chemical composition:
| Alloy | % | Ni | Cr | Mo | Nb | Fe | Al | Ti | C | Mn | Si | Co | P | S |
| Inconel 625 | maximum | margin | 20 | 8 | 3.15 | - | - | - | - | - | - | - | - | - |
| Minimum | 23 | 10 | 4.15 | 5 | 0.4 | 0.4 | 0.1 | 0.5 | 0.5 | 1 | 0.015 | 0.015 |
Physical properties:
| Density | 8.4g/cm |
| Melting point | 1290-1350℃ |
Minimum mechanical properties of Inconel 625 alloy at room temperature:
| Alloy state | Tensile strength Rm N/mm | Yield strength RP0.2 N/mm | Elongation A5 % | Brinell hardness HB |
| Solid solution | 760 | 345 | 30 | ≤220 |
Alloy properties:
1. Excellent corrosion resistance to various corrosive media in oxidizing and reducing environments
2. Excellent resistance to pitting and crevice corrosion, and will not produce stress corrosion cracking caused by chlorides
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
4. Excellent resistance to corrosion from various inorganic acid mixed solutions
5. At a temperature of 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
Metallographic structure:
625 has a face-centered cubic lattice structure. When kept at about 650℃ for a long enough time, carbon particles and unstable quaternary phase will precipitate and transform into a stable Ni3(Nb,Ti) orthorhombic lattice phase. After solid solution strengthening, the molybdenum and niobium components in the nickel-chromium matrix will improve the mechanical properties of the material, but the plasticity will be reduced.
Corrosion resistance:
Alloy 625 exhibits excellent corrosion resistance in many media. It has 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., and also has resistance to alkali and organic acid corrosion in oxidizing and reducing environments. Effective resistance to chloride ion reduction stress corrosion cracking. It hardly produces 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. It is resistant to carbonization and oxidation in static or cyclic environments, and is resistant to chlorine-containing gas corrosion.
Application Areas:
After softening and annealing, low-carbon alloy 625 is widely used in chemical process industry. Its good corrosion resistance and high strength enable it to be used as thinner structural components. Alloy 625 can be used in places where it contacts seawater and is subjected to high mechanical stress. Typical application areas:
1. Parts of organic chemical process technology containing chlorides, especially in places where acid chloride catalysts are used
2. Used to manufacture digesters and bleaching tanks in pulp and paper industry
3. Absorption towers, reheaters, flue gas inlet baffles, fans (humid), agitators, guide plates and flues in flue gas desulfurization systems
4. Used to manufacture equipment and components for acidic gas environments
5. Acetic acid and acetic anhydride reaction generators
