Nickel 200/201 is a pure, unalloyed nickel with excellent corrosion resistance properties. As a result, it is widely used to manufacture various chemical processing equipment, especially for handling caustic alkalis. Nickel 200/201 bars are a crucial component in this application, and as such, their specification and quality are critical to ensure reliable performance. In this blog post, we will delve into the properties and characteristics of nickel 200/201 bars and offer guidance on choosing the best quality bars for your application.
What is Nickel 200/201?
Nickel 200 is a commercially pure nickel that contains 99.6% nickel by weight. It exhibits excellent resistance to various chemicals, including hydrofluoric, sulfurous, and alkalis. Nickel 201, on the other hand, is a low-carbon version of nickel 200 with an even lower concentration of impurities. It is microstructurally purer than Nickel 200, and as such, it demonstrates superior resistance to corrosive environments. Nickel 200/201 bars are often preferred over other alloys because the metal’s price is relatively low and performs exceptionally well in acidic environments.
What are the properties of Nickel 200/201 bars?
Nickel 200 and 201 bars have excellent mechanical properties, such as high tensile strength, flexibility, and toughness. They can be easily welded, fabricated, and machined using conventional techniques. Also, nickel 200/201 bars demonstrate exceptional corrosion and oxidation resistance, making them suitable for use in a wide range of harsh environments. They can withstand a broad range of temperatures, from cryogenic temperatures (-273°C) up to 550°C.
How to choose the right Nickel 200/201 bars
When choosing the right nickel 200 bars for your application, it is essential to consider several factors, such as the temperature range of the application, the type of media/harsh environment it is exposed to, the bar dimensions, tolerance requirements, and surface finish. The nickel 200/201 bars should be sourced from reputable suppliers with a history of delivering high-quality products that meet the relevant industry standards. It is best to consult experts who can offer detailed guidance on the appropriate nickel 200/201 bars under different conditions.
Applications of Nickel 200/201 bars
Nickel 200/201 bars are used extensively in various industries, such as chemical processing, pharmaceuticals, food processing, and aerospace. In chemical processing, nickel 200/201 bars manufacture piping, heat exchangers, and valves that handle corrosive chemicals. The pharmaceutical industry uses nickel 200/201 bars to produce reactors, evaporators, and distillation columns. The food processing industry employs nickel 200/201 bars to produce equipment that handles highly acidic foods such as tomato paste and citric acid. Aerospace uses nickel 200/201 bars to manufacture aircraft engine components such as turbine blades and exhaust systems.
Maintenance of Nickel 200/201 bars
To maintain the corrosion resistance properties of nickel 201 bars, keeping them clean and free from contamination is essential. Regular cleaning using mild detergent and water is recommended. In addition, nickel 200/201 bars should not be exposed to prolonged contact with other metals, especially those that are significantly more anodic, such as copper and steel. This is because contact with such metals can result in galvanic corrosion of the nickel 200/201.
Conclusion
Nickel 200/201 bars are an excellent choice in various industries that handle corrosive media, extreme temperatures, and harsh environments. Choosing high-quality bars sourced from reputable suppliers is crucial to ensure reliable performance. Nickel 200/201 bars have excellent mechanical and corrosion resistance properties, and they are used in a wide range of applications, such as chemical processing, pharmaceuticals, food processing, and aerospace. By understanding the properties, characteristics, and applications of nickel 200/201 bars, you can make an informed decision when selecting the right bar for your application.
