Nickel 200 round bars are widely used in industries that demand high performance, durability, and corrosion resistance. Whether you are in the chemical processing, marine, or aerospace sector, understanding the key properties and benefits of Nickel 200 round bars can help you make an informed purchasing decision. In this blog, we will explore everything you need to know about Nickel 200 round bars, from their composition and features to applications and quality checks.
What is Nickel 200?
Nickel 200 is a solid-solution strengthened, unalloyed nickel alloy. It is identified by the UNS number N02200. Its chemical makeup includes over 99.6% nickel, with small amounts of iron, copper, manganese and carbon. Because of its high purity, it has excellent corrosion resistance and is ideal for both chemical and high-temperature environments. Nickel 200 round bars are available under standards such as ASTM B160 and come in various diameters and lengths to meet industrial needs.
Key Properties of Nickel 200 Round Bars
Corrosion Resistance
These round bars resist corrosion in neutral and alkaline solutions, especially in caustic alkali environments.
High Conductivity
They conduct heat and electricity well, making them suitable for electrical and thermal applications.
Magnetic and Mechanical Strength
Nickel 200 is magnetic at room temperature and has good mechanical properties, including moderate tensile strength.
Resistance to Caustic Substances
The material withstands acids and alkalis, especially sodium hydroxide, without breaking down.
Thermal Stability
Nickel 200 can handle a wide temperature range, maintaining its properties even at high temperatures.
Manufacturing Process of Nickel 200 Round Bars
Melting and Alloying
The process begins with melting pure nickel and adding trace elements. This is done in a controlled setting to maintain the alloy’s purity.
Hot and Cold Working
The molten metal is shaped through hot working. Cold working is then used to refine size and surface finish.
Heat Treatment
Bars are heat-treated through annealing or stress relieving to improve their formability and reduce internal stress.
Surface Finishing and Inspection
The surface is cleaned and polished as each bar undergoes inspection to meet industry standards and quality checks.
Applications of Nickel 200 Round Bars
Chemical Processing
Used in caustic soda plants and reactors, Nickel 200 handles strong alkalis without degrading, ensuring safety and performance.
Electronics and Electrical Components
Its electrical conductivity makes it a good choice for connectors, terminals, and battery components.
Aerospace and Marine Use
Resistant to corrosion and stress, these bars are used in fuel systems, fasteners, and marine fittings.
Food Processing Equipment
Nickel 200’s non-reactive nature ensures food safety, especially in handling alkali-based cleaning agents.
Heat Exchangers and Evaporators
The material handles high temperatures and corrosive environments well, making it suitable for heating systems.
Advantages of Using Nickel 200 Round Bars
Nickel 200 provides excellent long term performance in challenging atmospheres due to resistance to corrosion and caustic materials. Nickel 200 is easy to weld and form, making it good for custom fabrication. Non-reactive materials are essential to certain industries such as food and chemical processing. The bars also reduce maintenance and downtime, cutting costs over time.
How Nickel 200 Compares to Other Alloys
Nickel 200 has better corrosion resistance in alkali environments than many stainless steels. Compared to Nickel 201, it has higher carbon content, making it slightly stronger but less suitable for very high temperatures. When purity and conductivity are top priorities, Nickel 200 is preferred over other metals.
Standards and Certifications
Nickel 200 round bars are compliant with ASTM B160 and other international standards. They adhere strictly to industry norms of chemical composition, strength and quality. Every batch is tested for purity, hardness and resistance for performance and safety.
Tips for Choosing the Right Nickel 200 Round Bar Supplier
Look for suppliers with certified quality management systems and material traceability. Check if they have ready stock and can deliver on time. Also, ask about customization options like cutting, finishing, and value-added services to match your project needs.
Conclusion
Nickel 200 round bars are employed where purity, corrosion resistance, and strength are critical. From electrical components to chemical processing, their reliability and functionality are proven. Nickel 200 is the choice of industries when other metals are unable to endure the task.
