Nickel 200 tubing is made from commercially pure wrought nickel (typically 99.6% nickel). This alloy is known for its excellent corrosion resistance, good mechanical properties, and high thermal and electrical conductivity.
Excellent Corrosion Resistance: Nickel 200 exhibits outstanding resistance to many corrosive environments, particularly caustic alkalies. It also performs well in de-aerated acids and is resistant to distilled and natural waters.
Good Mechanical Properties: It possesses good tensile strength, toughness, and ductility, making it suitable for various fabrication processes, including welding and forming.
High Thermal Conductivity: This makes it useful in heat transfer applications.
High Electrical Conductivity: It's suitable for electrical and electronic components.
Magnetic and Magnetostrictive Properties: Nickel 200 is magnetic and exhibits magnetostrictive properties.
Low Gas Content and Vapor Pressure: These characteristics are beneficial in specific applications.
Weldability: It can be readily welded using conventional methods.
Nickel 200 is a commercially pure wrought nickel alloy, meaning it consists primarily of nickel (typically >99.0%) with small amounts of other elements. It is also known by the UNS designation N02200 and Werkstoff numbers 2.4060 and 2.4066.Think of it as just nickel that has been carefully refined, melted, and hot‑ or cold‑worked into usable mill products (tube, pipe, bar, plate, wire, forgings) while keeping impurities extremely low.

Carbon Content:
Nickel 200 has a maximum carbon content of 0.15%.
Nickel 201 is a low-carbon version with a maximum carbon content of only 0.02%.
High-Temperature Applications:
Nickel 200 is generally recommended for service below 600°F (315°C). At higher temperatures (around 800-1200°F or 425-650°C), the higher carbon content can lead to graphitization (carbon precipitation at the grain boundaries), which can embrittle the material and compromise its mechanical properties.
Nickel 201, with its lower carbon content, is preferred for service above 600°F (315°C) and can be used up to around 1250°F (677°C) in some applications. The lower carbon minimizes the risk of graphitization, maintaining the alloy's integrity at higher temperatures.
Fabrication:
Nickel 201 generally exhibits a lower work-hardening rate and lower annealed hardness compared to Nickel 200. This makes it more suitable for cold forming operations like deep drawing and spinning.
While both alloys have good weldability, the lower carbon content in Nickel 201 can sometimes offer slightly improved weldability and reduce the risk of weld-induced intergranular corrosion. However, the oxyacetylene welding process is generally not recommended for Nickel 201.
Mechanical Properties:
At room temperature, the mechanical properties of Nickel 200 and 201 are quite similar. Nickel 200 might exhibit slightly higher tensile and yield strength in some specifications, but the difference is generally not significant. The key difference in mechanical properties becomes apparent at elevated temperatures where Nickel 201 retains its strength and ductility better due to its resistance to graphitization.
Applications:
Nickel 200 is commonly used in chemical and food processing equipment, electronic components, and aerospace components where temperatures are generally lower.
Nickel 201 is often chosen for higher-temperature applications like caustic evaporators, combustion boats, heating element lead wires, and components in the chlor-alkali process.
Corrosion Resistance:
While both have excellent overall corrosion resistance, there might be subtle differences in specific environments due to the slight variation in composition. Some sources suggest Nickel 200 might have slightly better resistance in reducing environments, while Nickel 201 might have slightly better resistance in oxidizing environments in some cases, but their resistance to caustic alkalies is outstanding.
