UNS N08800 Nickel Alloy Seamless Tubes

Our UNS N08800 Nickel Alloy Seamless Tubes (commonly known as Alloy 800) are engineered for high-performance industrial applications operating under extreme temperatures and aggressive chemical environments. Manufactured from a nickel–iron–chromium alloy, these tubes provide excellent resistance to oxidation, carburization, and sulfidation, along with outstanding mechanical strength at elevated temperatures.

The seamless construction ensures a smooth internal surface, reducing pressure drops and enhancing fluid flow efficiency in critical systems. These tubes retain their structural stability and corrosion resistance during prolonged exposure to high heat, making them ideal for heat exchangers, furnaces, condensers, and power generation equipment.

Widely used in aerospace, petrochemical, power generation, and chemical processing industries, our UNS N08800 nickel alloy seamless tubes undergo rigorous quality control and testing to meet international performance standards. They offer a reliable, durable, and cost-effective solution for applications requiring long-term performance in harsh thermal and corrosive conditions.
