Standards and Equivalents
Nickel 200 round bar is produced according to ASTM B160 standards and equivalent specifications in other countries. Equivalent grades include Werkstoff 2.4066, DIN 2.4066, EN Ni 99.2, and JIS NW 2200.
Size, Form & Manufacturing Range
Factory suppliers offer Nickel 200 round bars in diameters from 3 mm to 800 mm and lengths from 1 m to 6 m, with custom lengths available. The bars may have bright, turned, or black finishes and are supplied in hot-finished, cold-drawn, or annealed conditions.
Corrosion Resistance & Application Advantages
Nickel 200 round bars are highly resistant to reducing acids, caustic solutions, and seawater. They are used in chemical processing, desalination, marine applications, aerospace, electronics, and heat exchangers due to their ductility, thermal and electrical conductivity, and high temperature strength.
Factory Pricing & Cost Factors
Factory prices vary depending on diameter, finish, and quantity. Bulk orders typically lower per-kg costs. Below is an example of price ranges:
| Diameter (mm) | Price per kg (USD) | Notes |
|---|---|---|
| 3–20 | 28–40 | Small and medium diameters |
| 21–50 | 30–38 | Medium diameters |
| 51–200 | 32–45 | Larger diameters |
| 201–800 | 35–50 | Extra-large diameters |
Factory Sourcing Strategies
To achieve factory-level pricing:
- Request quotations directly from certified factories.
- Specify alloy grade (N02200), diameter, length, finish, and heat treatment.
- Place bulk orders to lower unit cost.
- Ask for material test certificates and specification compliance.
- Consider production lead times and shipping logistics.
Handling and Storage Considerations
- Store bars in a dry environment to prevent surface contamination.
- Avoid exposure to strongly oxidizing acids.
- Use proper machining tools for cutting and forming nickel bars.
- Inspect for surface defects or cracks before use.
Quality Assurance and Testing
| Test / Certificate | Purpose |
|---|---|
| Material Test Certificate (MTC) | Certifies chemical composition and mechanical properties |
| Ultrasonic or Eddy-Current Inspection | Detects internal flaws |
| Dimensional Inspection Report | Ensures diameter, straightness, and tolerance meet specifications |
| Positive Material Identification (PMI) | Verifies correct alloy |
Comparison: Factory Bar vs Distributor Bar
| Aspect | Factory Purchase | Distributor Purchase |
|---|---|---|
| Unit Price | Lower per kg | Higher due to markup |
| Lead Time | Longer | Shorter (stocked items) |
| Certifications | Full traceability | May lack mill-level traceability |
| Customization | High | Limited |
