Nickel 200 Alloy
Nickel 200 Alloy Supplier in Tunisia
Introduction
Nickel 200 is a commercially pure wrought nickel alloy known for its excellent resistance to corrosion in many environments, good thermal and electrical conductivity, high ductility, and ease of fabrication. Designated as UNS N02200, Nickel 200 contains a minimum of approximately 99.0% nickel, with controlled amounts of other elements depending on the applicable product specification.
Nickel 200 is used in chemical processing, food processing, electronics, marine-related equipment, and industrial applications where its material characteristics suit the operating environment. Its performance depends on the corrosive medium, temperature, concentration, and service conditions.
Emirerri Steel supplies nickel alloys and industrial metal products for customers across Tunisia, North Africa, and international markets, subject to product availability and specification confirmation.

Dimensions, tolerances, surface finish, testing requirements, and documentation should be confirmed at the quotation stage.
Corrosion Resistance of Nickel 200
Nickel 200 provides good resistance in many alkaline environments, particularly caustic solutions under suitable conditions. It can also perform well in selected neutral and reducing environments.
However, corrosion resistance is not universal. Strong oxidizing media, certain acids, elevated temperatures, and specific chemical concentrations can affect performance. Material selection should therefore be based on the exact process chemistry, operating temperature, concentration, and exposure conditions.
For prolonged service at elevated temperatures where carbon-related effects are a concern, Nickel 201 (UNS N02201) may be a more appropriate option because of its lower carbon content.
Heat Treatment and Fabrication
Nickel 200 can be formed, machined, and fabricated using suitable methods. Work hardening can occur during cold forming, so fabrication procedures should account for the material’s condition and the degree of deformation.
Annealing may be used to restore ductility or achieve the required material condition. Heat-treatment parameters should follow the applicable product specification and qualified manufacturing procedure.
Welding
Nickel 200 can generally be welded using appropriate procedures and compatible nickel-alloy filler materials. The selected process, filler metal, joint preparation, cleanliness, and post-weld requirements should be determined by a qualified welding procedure based on the service conditions and applicable codes.
Avoid contamination from materials that may adversely affect weld quality or corrosion performance.
Applications
Nickel 200 is used in a range of industries, including:
- Chemical processing: Selected tanks, vessels, and process equipment.
- Caustic handling: Equipment exposed to suitable alkaline solutions.
- Food processing: Components where commercially pure nickel is appropriate and permitted by the applicable requirements.
- Electronics and electrical equipment: Selected conductors and components.
- Industrial equipment: Components requiring ductility, conductivity, and suitable corrosion resistance.
- Heat-transfer equipment: Selected tubes and components, subject to operating conditions and design requirements.
The suitability of Nickel 200 should be assessed for each application rather than assumed from the alloy designation alone.
