Nickel 200:

Nickel 200, with its 99.6% purity, stands as a paragon of commercially pure nickel. This wrought nickel exhibits robust mechanical properties and unparalleled resistance to corrosive environments. Its high thermal and electrical conductivities, along with low gas content and vapour pressure, make it highly desirable across industries.

High-Temperature Performance:

While Nickel 200 thrives at temperatures below 315°C, its properties can be compromised by graphitization at higher temperatures. For applications exceeding 315°C, Nickel 201 is recommended due to its superior performance under elevated temperatures.

Corrosion Resistance:

• Water: Nickel 200 showcases excellent corrosion resistance in distilled and natural waters, including hydrogen sulphide or carbon dioxide. It remains unaffected even in seawater environments.
• Acids: Nickel 200 demonstrates varying degrees of resistance to different acids, including sulphuric, hydrochloric, hydrofluoric, phosphoric, and nitric acids.
• Alkalies: Its outstanding corrosion resistance extends to caustic soda and other alkalis, with exceptions like ammonium hydroxide. Nickel 200 forms a protective film, nickel oxide, in caustic soda solutions, mitigating corrosion rates effectively.
• Salts: Nickel 200 exhibits resilience to stress-corrosion cracking in chloride salts and offers excellent resistance to non-oxidizing halides. However, oxidizing acid chlorides should be used with caution, and efforts should be made to remove chlorates from caustic solutions.
• Fluorine and Chlorine: Despite being strong oxidizers, Nickel 200 can withstand environments containing fluorine and chlorine under specific conditions. It forms a protective fluoride film at room temperature and effectively resists dry chlorine.

Note: Nickel 200 is extensively utilized in industries such as chemical processing, electronics, and food handling, where corrosion resistance and product purity are of utmost importance.
