Description
Nickel 201 Seamless Pipe and Tube
Product Overview and Enquiry Details
Nickel 201 (UNS N02201) is a low-carbon commercial nickel grade. Its lower carbon content reduces the risk of carbon-related embrittlement during elevated-temperature exposure compared with Nickel 200. Material selection still depends on the service medium, temperature, pressure, delivery condition and applicable design requirements.
For a Nickel 201 seamless pipe or tube quotation, send the outside diameter, wall thickness, length, quantity and required delivery condition. State whether the wall requirement is an average or minimum thickness, and include dimensional tolerances, service conditions, the required material standard and edition, and inspection documents.
ASTM B163 covers seamless condenser and heat-exchanger tubes within its specified scope. Confirm the applicable specification for the actual dimensions and intended use; the full size range listed below is not a blanket ASTM B163 compliance claim.
Material and Delivery Considerations
- Low-carbon nickel: Confirm UNS N02201 and the required composition against the order specification and material documentation.
- Corrosion suitability: Identify the process medium, concentration, temperature and other operating conditions before selecting the material.
- Seamless construction: Pressure suitability depends on dimensions, material condition, design rules and inspection requirements; seamless manufacture alone does not establish a pressure rating.
- Delivery condition: Specify annealed material if required for subsequent bending or fabrication, together with surface finish, straightness and end preparation requirements.
📏 Technical Specifications

Material selection note: Nickel 201’s lower carbon content is relevant to high-temperature embrittlement resistance. It does not establish a universal service temperature or guarantee resistance to every process medium. Review the operating conditions and applicable design requirements before ordering.
Processing and Delivery Requirements
Include any requirements for the production route, heat treatment and final condition in the enquiry. For annealed tube intended for bending or forming, specify the fabrication requirements as well as the finished dimensions.
Confirm the required surface finish, cut lengths, end preparation and dimensional tolerances before ordering. Inspection methods and acceptance criteria should be agreed for the actual material specification and application.
🌍 Applications of Nickel 201 Seamless Pipe
Include the process media and project specifications when enquiring about the following applications. Suitability depends on corrosion conditions, pressure, temperature and any project-specific qualification requirements.
-
Chemical Processing Plants – Heat exchangers, evaporators, and condensers.
-
Marine Engineering – Seawater desalination systems and offshore pipelines.
-
Food & Beverage Industry – Caustic cleaning solution handling and production equipment.
-
Electronics Manufacturing – Semiconductor fabrication components.
-
Power Generation – Steam generator tubing and nuclear power systems.
-
Pharmaceuticals – High-purity process pipelines.
📊 Performance Comparison – Nickel 200 vs Nickel 201
The comparison below is a material-selection overview. The low-carbon distinction does not define an operating-temperature limit; assess service conditions and the applicable design code for either grade.
| Property | Nickel 200 | Nickel 201 |
|---|---|---|
| Carbon Content (%) | ≤ 0.15 | ≤ 0.02 |
| Graphitization Risk | Higher | Minimal |
| Best Use Case | Low-temp chemical handling | High-temp, reducing atmospheres |
Selection guidance: Specify the service medium, concentration, temperature, pressure and delivery condition. Review corrosion behaviour and design requirements rather than choosing a grade from temperature or an application label alone.
🏭 Available Sizes & Tolerances
Use the listed sizes as an enquiry range. Confirm the available diameter, wall and length combination, tolerances and delivery condition. Dimensions outside ASTM B163’s scope require a separately confirmed specification; the table does not establish B163 compliance for every size.
| Outer Diameter (OD) | Wall Thickness (WT) | Length |
|---|---|---|
| 6 mm – 219 mm | 0.5 mm – 20 mm | Up to 12 m |
| Custom Ni201 tube sizes are available upon request. |
Standards and Documentation to Confirm
- ASTM B163: For seamless condenser and heat-exchanger tubes within the standard’s scope. Specify the required edition and confirm that the dimensions and condition are covered.
- ASME SB163: If required by the project, identify the applicable material and design-code requirements. A material specification reference alone does not establish approval of the finished system.
- Quality-system documents: If ISO 9001 certification is required, request the current certificate and its applicable scope before ordering.
- Material documentation: State whether EN 10204 3.1 documentation is required and confirm the documents to be supplied with the order.
Inspection Requirements
Specify the required inspections, sampling, acceptance criteria and reports in the enquiry. Confirm which requirements are included in the quotation rather than assuming every method is performed on every batch.
- Chemical analysis: Required grade and composition limits, with the agreed material report.
- Mechanical testing: Required tensile, hardness and elongation results for the specified condition and dimensions.
- Hydrostatic testing: Any required test pressure, procedure and acceptance criteria.
- Non-destructive examination: Any required eddy-current or ultrasonic examination method, extent and reporting.
Request a Nickel 201 Pipe or Tube Quotation
Send your dimensions or drawing, quantity, delivery condition, required standard, service conditions and inspection-document requirements. Include the delivery destination and required date so that the quotation can identify the proposed supply scope, documentation and lead time.
Confirm the agreed specification and documents before placing the order, including any project-specific inspection or qualification requirements.
