Pure nickel wire mesh material models and product application introduction
Pure nickel models: N4, N5, N6, N8, UNS N02200, UNS N02201.

The mechanical properties of nickel are close to those of carbon steel, but its resistance to alkaline corrosion is second only to silver among metal materials. A black protective film will form on the surface of nickel in concentrated alkali, making it very corrosion-resistant. Therefore, nickel is particularly suitable for manufacturing equipment for processing concentrated alkali solutions. The main factors affecting the service life of nickel equipment are the concentration, temperature, and impurity content of caustic soda, especially the content of NaCl and NaCIO3. The higher the concentration of alkali and the lower the impurity content, the longer the service life of nickel and nickel alloys. my country began to use nickel and nickel alloys in the chlor-alkali industry in the 1980s. Over the past decade, nickel and nickel alloys have played a very important role in the chlor-alkali industry.

Corrosion resistance of pure nickel
It is particularly resistant to alkali corrosion and is relatively stable in high temperature or molten alkali, so it is mainly used in the alkali industry. At room temperature , nickel is extremely stable in seawater, salt solutions and organic media (such as fatty acids, phenols, alcohols, etc.). It is not resistant to inorganic acid corrosion and is also unstable in acetic acid and formic acid.
