High-Purity UNS N02201 (Nickel 201) Forged Ring: Premium Anti-Graphitization Rolled Ring Blank for High-Temperature Caustic Alkali Service

High-Purity UNS N02201 (Nickel 201) Forged Ring

UNS N02201 Nickel 201 forged ring is a low-carbon commercially pure nickel seamless rolled forging, the low carbon variant of Nickel 200. It delivers outstanding corrosion resistance in caustic alkali and reducing media, with good ductility, weldability and high-temperature stability, avoiding graphitization embrittlement above 315℃. It is particularly suitable for caustic soda flanges, electrolyzer ring components and high-temperature alkali-resistant ring parts.

Key Features and Advantages

• Ultra-low carbon composition prevents high-temperature graphitization embrittlement, usable above 315℃.

• Excellent corrosion resistance to sodium hydroxide, caustic alkalis and reducing environments.

• High ductility, easy forming and reliable weldability.

• Good thermal and electrical conductivity.

• Dense rolled forging structure, uniform grain, suitable for high-pressure high-temperature service.

Typical Applications                             

• Caustic soda equipment flange blanks and sealing rings.

• Chlor-alkali industry electrolysis cell ring components.

• High-purity chemical vessel flange and connection rings.

• Vacuum equipment and electronic vacuum ring parts.

• Heat treatment furnace tooling rings and high-temperature furnace fittings.

• Alkali pump, valve and mechanical seal ring components.
