Product Sheet
Inconel 825
A high-performance superalloy designed for extreme environments and corrosive conditions.
About Inconel 825
Inconel 825 is a nickel-chromium-based alloy offering outstanding corrosion resistance, especially in acidic and oxidising environments, while also withstanding elevated temperatures. This alloy is frequently used in industrial applications where resistance to corrosive media—such as acids, chemicals, and seawater—is critical.
It is ideal for demanding environments across the chemical, petrochemical, marine, nuclear, and energy industries. Thanks to its specific composition, Inconel 825 delivers both mechanical strength and excellent thermal stability, making it a preferred choice for long-term, high-stress applications.
Technical Specifications and Composition of Inconel 825
Nickel-Based Alloy
Inconel 825 is primarily composed of nickel, giving it excellent resistance to heat and highly corrosive environments.
Ease of welding and machining
This alloy offers good weldability, making it suitable for complex part fabrication. It is also relatively easy to machine compared to other nickel alloys.
Mechanical properties
Inconel 825 maintains strong mechanical characteristics, even under extreme temperatures and in chemically aggressive conditions.
Excellent heat resistance
This alloy retains its mechanical strength and structural stability at elevated temperatures, up to approximately 850°C (1562°F).
Outstanding corrosion resistance
Highly resistant to acid attack—particularly sulfuric, phosphoric, and chlorinated solutions—Inconel 825 also provides strong resistance to oxidation in hot and dry environments.
