Product Overview –Nickel 201 Tubes
Nickel 201 Tubes, are premium commercially pure wrought nickel tubes containing a minimum of 99.6% nickel with an exceptionally low carbon content, making them ideal for high-temperature applications where resistance to graphitization is essential. Designated as UNS N02201, Nickel 201 offers outstanding corrosion resistance, excellent thermal and electrical conductivity, superior ductility, and outstanding resistance to caustic alkalis, neutral salts, and reducing chemical environments.
Compared to Nickel 200, Nickel 201 contains significantly lower carbon, allowing it to maintain excellent mechanical properties during prolonged exposure to temperatures above 315°C (600°F) without the risk of graphite precipitation. This makes it the preferred choice for high-temperature chemical processing and high-purity industrial applications.
These tubes are extensively used in chemical processing plants, caustic soda production, food processing, pharmaceutical manufacturing, electronics, heat exchangers, condensers, power generation, pressure vessels, aerospace, and nuclear industries.
