N5 Nickel Pipe | UNS N02201 Low Carbon Pure Nickel Tube
Short Description:
N5 Nickel Pipe (UNS N02201) is a high-purity, low-carbon nickel alloy pipe with excellent resistance to a wide range of corrosive environments. Its low carbon content (C ≤ 0.02%) minimizes carbide precipitation during welding, making it ideal for chemical processing, electronics, marine, and high-temperature environments.
N5 Nickel Pipe, also known by its international designation UNS N02201, is a high-purity, low-carbon nickel alloy pipe manufactured with a minimum nickel content of 99.95%. This premium-grade material is highly regarded for its outstanding corrosion resistance, particularly in alkaline media such as caustic soda and potassium hydroxide, as well as in mildly acidic and neutral environments. Thanks to its low carbon content (≤0.02%), N5 nickel pipe provides enhanced resistance to intergranular corrosion during welding and thermal processing, making it an ideal choice for critical chemical and electronic applications.
Manufactured in accordance with ASTM B161, GB/T 5235, and other global standards, N5 nickel pipes are available in both seamless and welded forms. They feature excellent ductility, good mechanical strength, and superb thermal and electrical conductivity. These properties make N5 nickel tubing suitable for use in high-purity piping systems, chemical processing plants, marine engineering, power generation, battery production, and vacuum technology.

| FAQ : |
Q1: What is N5 Nickel Pipe?
A: N5 Nickel Pipe is a high-purity nickel alloy pipe with a minimum nickel content of 99.95%. It corresponds to UNS N02201, a low-carbon grade nickel known for its excellent corrosion resistance and weldability, especially in caustic alkaline environments.
Q2: What is the difference between N5 and Nickel 200 or N02200?
A: While all are commercially pure nickel grades, N5 (UNS N02201) has a lower carbon content than N02200 (Nickel 200), which improves its performance in welding and high-temperature environments by minimizing carbide precipitation and intergranular corrosion.
Q3: What industries commonly use N5 Nickel Pipes?
A: N5 Nickel Pipes are widely used in the chemical processing industry, caustic soda production, battery manufacturing, electronics, marine engineering, food processing, and vacuum systems due to their excellent corrosion resistance and purity.
Q4: What standards does N5 Nickel Pipe comply with?
A: N5 Nickel Pipe meets international standards including ASTM B161, GB/T 5235, and JIS H4552. It is available in both seamless and welded types.
