ASTM B163 UNS N02200 / DIN 2.4066 / Alloy 200 Nickel Seamless Tube

Overview:

Alloy 200 seamless tubes are primarily composed of nickel, offering excellent corrosion resistance and high strength at elevated temperatures. These tubes are particularly notable for their versatility and durability, making them suitable for various applications across multiple industries such as chemical processing, aerospace, and marine environments.

The material is characterized by its excellent mechanical properties, including good ductility, high strength, and resistance to stress-corrosion cracking. With a nickel content of around 99.0%, Alloy 200 exhibits outstanding resistance to reducing environments. It performs well against alkalis and certain organic compounds, while its resistance to oxidizing agents is relatively limited.

Alloy 200 is often used in applications where good weldability is essential. This property allows for ease of fabrication, enabling manufacturers to create complex shapes while retaining structural integrity. The seamless design of the tube minimizes weaknesses found in welded seams, enhancing reliability in high-pressure or high-temperature scenarios.

In terms of temperature resistance, Alloy 200 maintains its mechanical properties at elevated temperatures, making it suitable for applications that involve heat exchangers, pressure vessels, and piping systems. The smooth surface finish of seamless tubes also aids in reducing friction and enhancing flow efficiency in fluid transport applications.
