Inconel 825 polished bar
Inconel 825 polished bar is a high-performance alloy bar based on nickel-iron-chromium. It is made smooth and shiny or a little shiny by careful work. It has a lot of nickel (40%), chromium (21%), molybdenum (3%), and copper (2%). It also has a bit of titanium and aluminum to make it stronger against damage. The shiny surface looks good and helps it stay strong against bad things on the outside.
Inconel 825 polished bar is very good at fighting against bad things like chemicals, staying strong when it's hot, and looking nice with its shiny surface. It is used in many places like chemical factories (for cleaning machines and parts that mix things), ocean machines (for parts that pump salty water), energy places (for handling nuclear fuel and getting oil and gas from places with lots of bad sulfur), and cleaning places (for burning trash and cleaning dirty water). Using it makes things last longer and saves money on fixing them.
Features of Inconel 825 polished bar
Excellent corrosion resistance: Inconel 825 polished bar works well in strong acids like sulfuric acid and phosphoric acid and in chloride environments. It can resist pitting and stress corrosion cracking even in high temperature and high pressure.
High-temperature stability: Inconel 825 polished bar can keep its performance from -200℃ to 550℃. It is good for situations with big temperature changes.
Good mechanical properties: Inconel 825 polished bar has high tensile strength (≥586 MPa) and ductility. It is good for precision machining.
Surface advantages: The polished surface of Inconel 825 polished bar reduces porosity and the risk of pollutant adhesion. This helps it last longer.
Applications of Inconel 825 polished bar
Chemical equipment: Inconel 825 polished bar is used to make pickling equipment, reactor agitator shafts and valve parts. It can stand up to mixtures of sulfuric acid and nitric acid.
Marine engineering: Inconel 825 polished bar is used in pump shafts of desalination systems and fasteners for undersea pipelines. It can resist corrosion from saltwater.
Energy sector: Inconel 825 polished bar is used as structural components in nuclear fuel processing equipment. It is also used in downhole tools for oil and gas extraction in high-sulfur environments.
Environmental protection industry: Inconel 825 polished bar is used in high-temperature dust-resistant parts of incinerators and in chloride-resistant components of wastewater treatment systems.
