High-Purity UNS N02201 (Nickel 201) Forged Discs: Premium Anti-Graphitization Components for High-Temperature Caustic Processing

Nickel 201 (UNS N02201) Forged Discs

UNS N02201 Nickel 201 forged disc is a low-carbon commercially pure nickel forging, the low carbon version of Nickel 200. It provides excellent corrosion resistance in caustic alkali and reducing media, with good ductility, weldability and high-temperature stability, avoiding graphitization embrittlement above 315°C. It is particularly suitable for caustic soda equipment, high-purity chemical vessels and high-temperature corrosion-resistant components.

Key Features and Advantages

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

• Outstanding corrosion resistance to caustic soda, alkalis and reducing environments

• Excellent ductility, easy forming and reliable weldability

• Good thermal and electrical conductivity

• Dense forging structure, suitable for high-pressure and high-temperature service

Typical Applications

• Caustic soda / sodium hydroxide production equipment

• Chlor-alkali industry electrolysis cell components

• High-purity chemical reactors and storage vessels

• Vacuum equipment and electronic vacuum parts

• Heat treatment fixtures and high-temperature furnace fittings

• Alkali handling pumps, valve internals and flanged discs
