Nickel 200 is a low-carbon, pure nickel material with a nickel content of at least 99.6%. The "200" in the name comes from its UNS numbering system designation, N02200. HT PIPE is a well-established stockist and exporter, specializing in international trade for 15+ years. We deliver nickel 200 pipes, plates, bars, and a full line of pipe fittings, flanges, and structural components. Get in touch for free price lists and technical data-we're here to assist.
Why Choose Nickel 200 Pipe?
Nickel alloy 200 welded pipe Corrosion Resistance
- Caustic Alkali (Alkali): Nickel 200 is the material of choice for handling alkali solutions of all concentrations and temperatures, including sodium hydroxide (NaOH). It forms a protective passive film in alkali solutions, offering excellent resistance even in molten alkali, without the "alkali embrittlement" phenomenon that can occur with austenitic stainless steel. This is the foundation of its unshakable position in the chlor-alkali industry.
- Reducing Media: It exhibits excellent corrosion resistance to dry halogens (such as chlorine and fluorine), hydrochloric acid (HCl), phosphoric acid (H₃PO₄), and sulfuric acid (H₂SO₄) at room temperature, especially in non-aerated solutions with concentrations below 70%.
- Neutral and Weakly Alkaline Salt Solutions: Stable in marine environments and salt processing.
- High-Purity Water: Does not introduce metal ion contamination into ultrapure water, making it suitable for the electronics and food industries.

- High Toughness and Ductility: Pure nickel has a face-centered cubic (FCC) crystal structure, maintaining extremely high toughness and ductility even at low temperatures, making it easily formable by both hot and cold working.
- Moderate Strength: Its mechanical properties can be significantly improved by cold working. Typical yield strength in the annealed state is approximately 100 MPa and tensile strength is approximately 400 MPa. This yield strength can be increased to over 500 MPa through cold working.

- Magnetic Properties and Magnetostriction: Nickel 200 is a ferromagnetic material with high magnetic permeability and significant magnetostrictive properties (dimensional change in a magnetic field). This makes it suitable for components such as shielding shells and waveguides in the electronics and telecommunications industries.
- High Thermal and Electrical Conductivity: Its thermal and electrical conductivity are significantly higher than stainless steel, making it suitable for applications requiring heat exchange and electrical conductivity.
- Low Gas Permeability: Its extremely low permeability to gases such as oxygen, nitrogen, and hydrogen makes it an ideal material for creating high vacuum environments.
