Nickel 201 Tubes Supplier in India
What Are Nickel 201 Tubes?
Nickel 201 Tubes are commercially pure nickel tubes with a low carbon content, offering excellent corrosion resistance, good ductility, thermal conductivity and reliable performance in reducing and caustic environments. Nickel 201, designated as UNS N02201, is a low-carbon version of Nickel 200 and is particularly suitable for applications involving elevated temperatures.
Nickel 201 Tubes are valued for their excellent resistance to caustic alkalis, good resistance to reducing environments, high ductility, good thermal and electrical conductivity and lower carbon content. The low carbon composition helps reduce the risk of carbon embrittlement and makes Nickel 201 more suitable than Nickel 200 for certain higher-temperature applications.
These tubes are used in chemical processing equipment, caustic handling systems, heat exchangers, food processing equipment, electrical components, aerospace systems and specialized industrial equipment. The required tube size, wall thickness, length, finish and material condition are selected according to the specific application and operating conditions.
Kamal Steels is a reliable Nickel 201 Tubes Supplier and Exporter in India, supplying tubes in different sizes, wall thicknesses, lengths and finishes according to customer and project requirements. We also cater to international requirements with suitable export packaging and documentation.
