Inconel 625 polished bar
Inconel 625 polished bar is a high-performance alloy material based on nickel and chromium. It has a smooth metallic luster and uniform geometric dimensions after precision machining and surface polishing. The alloy is strengthened by adding elements like molybdenum (Mo) and niobium (Nb). It has excellent corrosion resistance, high-temperature strength and oxidation resistance. It is used to make key parts in harsh environments.
Inconel 625 polished bar is widely used in aerospace (engine parts, rocket propulsion systems), marine engineering (submarine components, seawater pump shafts), chemical energy (nuclear reactor pipes, heat exchangers) and medical food equipment. Thanks to its high-temperature resistance, corrosion resistance and excellent mechanical properties, it is a key material choice in harsh environments.
Features of Inconel 625 polished bar
Excellent corrosion resistance: Inconel 625 polished bar is highly resistant to chloride stress corrosion, seawater, acidic media (such as sulfuric acid and hydrochloric acid), and oxidative environments.
Stable high-temperature performance: Inconel 625 polished bar maintains high strength from -200℃ to 1000℃. It has excellent oxidation resistance and is suitable for high-temperature and high-pressure applications.
Excellent mechanical properties: Inconel 625 polished bar has high tensile strength (≥830 MPa) and fatigue life. It has a low tendency for work hardening, which makes it easy to form.
Surface treatment advantages: The polishing process of Inconel 625 polished bar reduces surface defects. It improves fatigue resistance and wear resistance. It also lowers fluid drag or friction coefficient.
Applications of Inconel 625 polished bar
Aerospace: Inconel 625 polished bar is used in engine parts, combustion chamber liners, and rocket propulsion systems.
Marine engineering: Inconel 625 polished bar is used in submarine parts, seawater valves, pump shafts, and other salt spray corrosion-resistant components.
Chemical and energy: Inconel 625 polished bar is used in nuclear reactor pipes, flue gas desulfurization systems, and high-pressure heat exchangers.
Medical and food: Inconel 625 polished bar is used in surgical instruments and food processing equipment that are resistant to disinfectant corrosion.
