Nickel 201 (UNS N02201) – Low-Carbon Commercially Pure Nickel Supplier of Round Bars, Tubes & Plates | Shanghai Hangbo Alloy Group

Nickel 201 (UNS N02201) is the low-carbon version of Nickel 200, containing a maximum of 0.02% carbon. This subtle modification is crucial for applications involving temperatures above 315°C (600°F). Unlike Nickel 200, Nickel 201 is not subject to embrittlement by intergranularly precipitated carbon when exposed to high temperatures for long durations. It retains the excellent corrosion resistance, high electrical conductivity, and magnetic properties of its predecessor, making it the preferred choice for heavy-duty chemical processing and high-temperature caustic handling.

Standards

Physical & Mechanical Properties

Depth Characteristics

1. High-Temperature Stability: Resistant to graphitization and embrittlement at temperatures up to 600°C.
2. Exceptional Ductility: Slightly softer than Nickel 200, allowing for superior deep-drawing and cold-forming properties.
3. Caustic Resistance: The industry standard for equipment handling molten caustic soda and anhydrous ammonia.
4. Conductive Efficiency: Maintains high thermal and electrical efficiency across a wide temperature range.
5. Magnetic Consistency: Reliable ferromagnetic properties for specialized electronic and sensing equipment.

Global Project Cases

• Caustic Concentrators: Used in the construction of large-scale evaporators for the production of high-purity caustic soda.
• Hydrogenation Reactors: Critical for chemical reactions requiring high purity and resistance to neutral/reducing environments.
• Aerospace Components: Combustion chamber parts and specialized lead wires requiring reliability at elevated temperatures.

Manufacturing & Testing

Our Nickel 201 production involves strictly controlled vacuum melting to keep carbon levels below the critical 0.02% threshold. We utilize **advanced ICP-OES spectrometers** for definitive chemical validation. Every coil and bar is tested for grain size and mechanical properties to ensure optimal performance in high-temperature caustic environments. Spectrometer实测 verification is mandatory for every heat to guarantee the low-carbon specification.

6+ Professional FAQs

1. Why choose Nickel 201 over Nickel 200?

If your application exceeds 315°C (600°F), Nickel 201 is mandatory to prevent carbon embrittlement and subsequent failure.

2. Is Nickel 201 softer than Nickel 200?

Yes, due to the lower carbon content, it has slightly lower hardness and yield strength, which makes it easier to form and draw.

3. Can Nickel 201 be used in chlorine gas?

Yes, it has excellent resistance to dry chlorine and hydrogen chloride at elevated temperatures up to approximately 550°C.

4. What is the Curie temperature of Nickel 201?

Approximately 360°C, providing consistent magnetic properties for electronic applications.

5. Is it suitable for high-temperature food processing?

Absolutely. It is widely used where product purity is paramount and high-temperature cleaning or processing is required.

6. How is Nickel 201 welded?

Standard welding techniques (TIG/MIG) are used, but low-carbon filler metals must be used to maintain the alloy's specialized properties in the weld zone.
