Inconel625

inconel625 is a grade of alloy with a density of 8.4 g/cm3 and a melting point of 1290-1350°C. Excellent corrosion resistance to inorganic acids and very good resistance to various corrosive media in both oxidizing and reducing environments. Alloy 625 exhibits excellent corrosion resistance in many media. It has excellent resistance to pitting, crevice corrosion, intergranular corrosion and erosion in chloride media.

Inconel 625 alloy has the following properties. 1. Excellent corrosion resistance to various corrosive media in both oxidizing and reducing environments 2. Excellent resistance to pitting and crevice corrosion, and no stress corrosion cracking due to chlorides 3. Excellent corrosion resistance to inorganic acids, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and a mixture of sulfuric and hydrochloric acids, etc. 4. Excellent resistance to corrosion of mixed solutions of various inorganic acids 5. When the temperature reaches 40℃, it can show good corrosion resistance in various concentrations of hydrochloric acid solutions 6. Good processability and weldability, no post-weld cracking sensitivity 7. With wall temperature in -196 ~ 450 ℃ pressure vessel manufacturing certification 8. Certified by the American Society of Corrosion Engineers NACE standard (MR-01-75) to meet the highest standard grade VII for use in sour gas environments Metallographic structure of Inconel 625 625 is a face-centered cubic lattice structure. When held at approximately 650°C for a long enough time, carbon particles and unstable quaternary phases will precipitate and transform into a stable Ni3(Nb,Ti) rhombohedral lattice phase. The molybdenum and niobium components of the solid solution strengthened nickel-chromium matrix will improve the mechanical properties of the material, but the plasticity will be reduced. Corrosion resistance of Inconel 625 Alloy 625 exhibits excellent corrosion resistance in many media.
