Nickel, whether commercially pure or low-alloyed, boasts versatile properties suitable for various industries, including chemical processing and electronics. This robust material offers exceptional resistance to reducing chemicals and caustic alkalis while maintaining high electrical and thermal conductivity.

Nickel 200: Nickel 200, a commercially pure (99.6%) wrought nickel, stands out for its mechanical properties and remarkable corrosion resistance in diverse environments. Notable features include high thermal and electrical conductivities, low gas content, and low vapour pressure. Its corrosion resistance makes it indispensable for applications demanding product purity, such as in the handling of foods, synthetic fibres, and caustic alkalis.

High-Temperature Properties: While Nickel 200 is typically utilized at temperatures below 315°C, precautions should be taken as higher temperatures may lead to graphitization, compromising its properties. For temperatures above 315°C, Nickel 201 is recommended.

Corrosion Resistance:

• Water: Nickel 200 demonstrates excellent resistance to corrosion in distilled and natural waters, including those containing hydrogen sulphide or carbon dioxide and even seawater.
• Acids: Nickel 200 exhibits resistance to various acids, including sulphuric, hydrochloric, hydrofluoric, phosphoric, and nitric acids, under specific concentrations and temperature conditions.
• Alkalies: Notably, Nickel 200 displays outstanding corrosion resistance to caustic soda and other alkalis, forming a protective nickel oxide film that mitigates corrosion rates over time.
• Salts, Fluorine, and Chlorine: Nickel 200 showcases remarkable resistance to chloride salts, non-oxidizing halides, and neutral/alkaline salt solutions. While it reacts with strong oxidizers like fluorine and chlorine, Nickel 200 can be utilized in such environments under certain conditions, forming protective films to mitigate corrosion.
