Seamless Incoloy 825 Nickel Alloy Steel Tube

Seamless Incoloy 825 Nickel Alloy Steel Tube is a high-performance piping product made from Incoloy 825 (a registered trademark of Special Metals Corporation), an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium.It is a seamless pipe, meaning it's manufactured without a welded seam, providing superior structural integrity, especially under high pressure and temperature applications.
The alloying elements provide broad resistance to a wide range of corrosive environments:
• Chloride-Ion Stress-Corrosion Cracking: High nickel content provides excellent resistance.
• Pitting and Crevice Corrosion: Enhanced by the molybdenum content.
• Reducing Agents and Acids: Nickel, molybdenum, and copper provide outstanding resistance to agents like sulfuric acid and phosphoric acid.
• Oxidizing Agents: Chromium confers resistance to oxidizing substances like nitric acid.
• Intergranular Corrosion: The titanium addition, combined with appropriate heat treatment, stabilizes the alloy, making it resistant to intergranular attack, even after welding.
