Inconel 625 is a solid solution-strengthened nickel-based deformed superalloy with molybdenum rhenium as the main strengthening element. It has excellent corrosion resistance and oxidation performance. It has good tensile and fatigue properties from low temperature to 980 °C, and is resistant to salt. Stress corrosion under a foggy atmosphere. Therefore, it can be widely used in the manufacture of aero-engine components, aerospace structural components and chemical equipment.
The characteristics of inconel 625:
1. Excellent corrosion resistance to various corrosive media in oxidation and reduction environments
2. Excellent resistance to pitting and crevice corrosion, and no stress corrosion cracking due to chloride
3. Excellent corrosion resistance to inorganic acids, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and mixed acid of sulfuric acid and hydrochloric acid.
4. Excellent corrosion resistance to mixed inorganic acid solutions
5. When the temperature reaches 40 C, it shows good corrosion resistance in hydrochloric acid solutions of various concentrations.
6. Good workability and weldability, no post-weld cracking sensitivity
7. Manufacturing Certification of Pressure Vessels with Wall Temperature ranging from -196 to 450 C
Metallographic Structure of Inconel 625:
Inconel 625 is a face-centered cubic lattice structure. Carbon particles and unstable quaternary phases will be precipitated and transformed into stable Ni3 (Nb, Ti) oblique lattice phase after holding at 650 C for a long time. The molybdenum and niobium components in nickel-chromium matrix after solution strengthening will improve the mechanical properties of the material, but the plasticity will be reduced.
