Advantages of Alloy 825:
High Temperature Stability: Alloy 825's ability to maintain its mechanical properties and corrosion resistance over extended periods of time at elevated temperatures makes it suitable for high temperature industrial processes.
Corrosion Resistance: Due to its unique chemical composition, Alloy 825 has excellent resistance to a wide range of corrosive media, including sulfuric acid, phosphoric acid and seawater.
Ease of Processing: Despite its high strength and corrosion resistance, Alloy 825 can be processed through conventional metalworking techniques to suit a variety of applications.
Weldability: Alloy 825 can be welded using a variety of welding techniques, and welded joints have similar properties to the base material, ensuring the fabrication and repair of complex structures.
Application Areas:
Oil & Gas Industry: In oil and gas refining and processing facilities, Alloy 825 is used to manufacture piping, heat exchangers and valves that are resistant to high temperatures and pressures, as well as other equipment exposed to corrosive chemicals.
Chemical industry: Alloy 825 is used in the manufacture of reactors, columns and piping in chemical plants, especially when handling corrosive chemicals.
Marine and Offshore: In offshore platforms, deep-sea pipelines and ship components, Alloy 825 is widely used for its excellent resistance to seawater corrosion.
Nuclear power industry: Due to its radiation resistance, Alloy 825 is used in key components of nuclear reactors and cooling systems in nuclear power plants.
Environmental protection equipment: Alloy 825's corrosion resistance makes it suitable for use in the construction of wastewater treatment and desulfurization facilities, which helps reduce environmental pollution.
