Nickel Flange
Stellanox Steel manufactures and supplies high-performance Nickel Flanges designed for corrosive, high-temperature, and high-pressure environments. Engineered from premium grades such as Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201), our nickel flanges offer exceptional chemical resistance, thermal stability, and dimensional accuracy—making them ideal for chemical plants, marine systems, power plants, aerospace, and nuclear applications.
Available in all standard and custom configurations—weld neck, socket weld, slip-on, blind, threaded, lap joint, and orifice—our flanges are compliant with ASME, ASTM B564, DIN, EN, and ISO specifications.
What are Nickel Flanges?
Nickel Flanges are circular connectors used to join piping, valves, pumps, and other equipment within piping systems. They are essential in industries where resistance to corrosion, long service life, and secure fluid/gas sealing are required. Nickel flanges provide excellent compatibility with aggressive chemicals, alkalis, and chloride-rich environments, while also offering superior mechanical strength and conductivity.
Both Nickel 200 (standard) and Nickel 201 (low-carbon) are widely used depending on the temperature and welding requirements of the system.
