Inconel 625 Metallurgical structure
625 for the face-centered cubic lattice structure. After incubation for sufficient time at about 650 ℃, the deposited carbon particles and unstable quaternary phase and into stable Ni3 (Nb, Ti) phase orthorhombic lattice. Nickel-chromium matrix molybdenum, niobium solid solution strengthening component will improve the mechanical properties of the material, but the plastic will be reduced.

Inconel 625 application
1.Organic Chemistry Process Technology of chloride-containing components, particularly in the case of using an acid chloride catalyst
2.For the manufacture of pulp and paper industry and bleaching digester tank
3.FGD absorber system, another heater flue gas inlet baffle, fan (wet), stirrer, baffle and flue
4.Applied to the acidic environment for the manufacture of gas equipment and components
5.Acetic acid and acetic anhydride generator
6.Sulfuric acid condenser
