Alloy 825 UNS N08825 is a nickel-iron-chromium alloy with molybdenum, copper, and titanium. This combination of elements provides the Incoloy 825 with exceptional corrosion resistance, making it highly suitable for a wide range of applications in industries such as chemical processing, oil and gas, and desalination. The UNS N08825 material is often used in environments that contain sulfuric acid, phosphoric acid, and aqueous corrosion-resistant alloy systems.
Alloy 825 UNS N08825 Material Properties:
1. Corrosion Resistance:
One of the most significant properties of Incoloy alloy 825 is its excellent resistance to corrosion. This resistance is due to the high content of nickel, molybdenum, and copper in the alloy. This makes Incoloy 825 UNS N08825 resistant to both reducing and oxidizing environments, as well as to pitting and crevice corrosion.
2. High Strength:
Alloy 825 UNS N08825 has a specific strength of approximately 850 MPa (123,000 psi) in the annealed condition and up to 1,344 MPa (195,000 psi) in the solution annealed condition. This is due to the presence of molybdenum and copper.
3. Heat Resistance:
Nickel alloy 825 has a high resistance to heat and can be used in applications with temperatures up to 1000°F (538°C).
4. Weldability:
The 2.4858 alloy 825 is very weldable, allowing for easy fabrication of parts and structures. Welding can be performed using conventional welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and submerged arc welding (SAW).
5. Resistance to Sulfuric Acid:
Inconel alloy 825 pipe has outstanding resistance to sulfuric acid in a range of concentrations and temperatures, thus making it an ideal material choice for chemical processing applications.
6. Non-magnetic:
Incoloy 825 material is classified as non-magnetic and is suitable for use in applications where magnetism can be detrimental.
