Nickel 200 Round Bars are used in many industries because of their excellent strength, corrosion resistance, and high purity. These round bars are made from commercially pure nickel (about 99.6%) and are perfect for use in chemical, marine, and electrical applications. However, to ensure quality and performance, Nickel 200 Round Bars must follow certain international standards and specifications.
In this blog, we’ll explain the most common standards and specifications in simple words. We’ll also discuss why it’s important to know these standards when choosing a nickel bar supplier.
What Are Nickel 200 Round Bars?
Nickel 200 Round Bars are solid cylindrical bars made from pure nickel. They are known for:
- High resistance to corrosion
- Good electrical conductivity
- Excellent mechanical properties
- Resistance to caustic alkalis and acids
These bars are often used in manufacturing equipment for the chemical and food industries, electrical components, marine equipment, and more.
Why Are Standards Important?
Standards ensure that the material, size, strength, and chemical composition of the Nickel 200 Round Bars meet specific quality levels. When you buy from a trusted nickel bar supplier, these standards help guarantee that the product is safe, reliable, and suitable for your needs.
Without proper standards, there’s a risk of using bars that might fail under pressure, corrode quickly, or not fit into the intended equipment.
Most Common Standards for Nickel 200 Round Bars
Below are the major standards that most Nickel 200 Round Bars follow. These are accepted globally and followed by suppliers and industries around the world.
1. ASTM B160
This is the most widely used standard for Nickel 200 Round Bars.
ASTM B160 covers specifications for nickel rod and bar made from Nickel 200 and Nickel 201. This includes:
- Chemical composition
- Mechanical properties
- Dimensions and tolerances
- Testing and inspection requirements
According to ASTM B160:
- Nickel content must be at least 99.6%
- Bars should have proper tensile strength and elongation
- Surface finish must be clean and free from cracks
If you’re choosing a nickel bar supplier, make sure their products follow ASTM B160.
2. ASME SB-160
ASME SB-160 is the same as ASTM B160 but follows the American Society of Mechanical Engineers standards. It is mainly used in pressure vessel and piping applications.
If your project is related to boilers or pressure systems, check that the round bars follow ASME SB-160. Most Nickel 200 Round Bars used in high-stress environments follow this standard.
3. UNS N02200
UNS (Unified Numbering System) is a system used to identify metals and alloys. Nickel 200 is listed as UNS N02200.
This specification confirms the chemical makeup of the material:
- Nickel: minimum 99.6%
- Iron: maximum 0.4%
- Copper: maximum 0.25%
- Manganese and other elements in small amounts
The UNS N02200 tag ensures the bar is made from pure nickel with minimal impurities.
4. EN 2.4066 / 2.4060
This is the European standard for Nickel 200 Round Bars. The numbers refer to the material grade:
- 2.4066: For round bars
- 2.4060: For other shapes like plates and sheets
If your project is based in Europe or follows European norms, look for these grades when buying from a nickel bar supplier.
5. DIN Standards
DIN stands for “Deutsches Institut für Normung,” or the German Institute for Standardization. DIN 17752 is commonly used for nickel rods and bars.
DIN standards are widely followed in Europe and are known for their detailed quality control. Many international buyers trust DIN-compliant Nickel 200 Round Bars for high-precision work.
6. ISO Standards
The International Organization for Standardization (ISO) also provides standards for nickel alloys, including Nickel 200. ISO 6208, for example, is used for nickel and nickel alloy rods and wires.
ISO standards help ensure global compatibility, especially if you’re dealing with international suppliers or clients.
7. JIS H4551 (Japan)
For projects following Japanese Industrial Standards (JIS), JIS H4551 is the go-to specification for nickel bars.
This standard outlines:
- Dimensional accuracy
- Surface finish
- Chemical composition
- Mechanical properties
A nickel bar supplier providing JIS-compliant Nickel 200 Round Bars is a good choice for Japan-based or Japanese-standard projects.
Key Mechanical Properties to Know
Most standards define certain mechanical properties that the Nickel 200 Round Bars must meet:
| Property | Typical Value |
|---|---|
| Tensile Strength | 340 MPa – 550 MPa |
| Yield Strength | ≥ 100 MPa |
| Elongation | ≥ 40% |
| Hardness | ≤ 60 HRB |
| Density | ~8.89 g/cm³ |
| Melting Point | 1446°C |
These values can vary slightly depending on the form, heat treatment, and standard followed.
Typical Sizes and Tolerances
Nickel 200 Round Bars come in various sizes depending on the requirement. Common sizes include:
- Diameter: 6 mm to 300 mm
- Length: Up to 6 meters (custom cut lengths also available)
- Tolerances: Based on standards like ASTM B160 or EN 10278
Make sure your nickel bar supplier can provide bars within the size and tolerance limits needed for your specific project.
Applications of Nickel 200 Round Bars
Thanks to their excellent properties, Nickel 200 Round Bars are used in:
- Chemical Processing Plants: For handling acids and alkalis
- Food Processing Equipment: Non-toxic and corrosion-resistant
- Electrical Equipment: Due to high conductivity
- Marine Industry: Saltwater resistance
- Battery Manufacturing: For high-purity requirements
In all these applications, following the right standards ensures safe and long-term performance.
How to Choose the Right Nickel Bar Supplier
Now that you understand the key standards, here are a few things to check when selecting a nickel bar supplier:
- Do they follow international standards like ASTM B160 or DIN 17752?
- Can they provide test certificates and inspection reports?
- Do they offer customization in terms of size and length?
- Are their products suitable for your industry’s requirements?
A reliable nickel bar supplier will always be transparent about the standards their bars meet and provide detailed documentation with every order.
Conclusion
Understanding the common standards and specifications for Nickel 200 Round Bars helps you make informed decisions while buying and using these bars in different applications. Standards like ASTM B160, ASME SB-160, UNS N02200, and EN 2.4066 ensure that the bars are safe, durable, and high in quality.
When sourcing from a nickel bar supplier, always check that their products comply with these specifications. Doing so ensures safety, saves money in the long run, and gives you confidence in the material’s performance.
