Product Details------------------------------------------------ ------------------------

Nickel plate (Ni201/N4, Ni200/N6)

It shows good corrosion resistance in many acidic and alkaline environments, and is mostly used in reducing media. The biggest feature of nickel is its resistance to corrosion by alkaline media, such as caustic potassium and caustic soda. It is widely used in ion-exchange membrane caustic soda technology. Nickel has good corrosion resistance in dry fluorine. Nickel has also been successfully used in dry chlorine and hydrogen chloride at room temperature to 540°C. It can also be applied to static hydrofluoric acid solution. Nickel has good mechanical properties in a relatively wide temperature range, is easy to cold work (elongation: δ≥40~60%), and its processing characteristics are similar to low carbon steel.

Nickel plate purity: above 99.95%

The difference between N4 and N6 pure nickel plates: The difference between N4 and N6 lies in the content of C, namely: low carbon pure nickel and ordinary pure nickel respectively

(Ie N4 /Ni201, N6/Ni200)

N6 Ni%=99.5%-99.6% C%=0.10%Max

Pure nickel 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. Nickel is extremely stable in seawater and salt solutions and organic media (such as fatty acids, phenols, alcohols, etc.) at room temperature. Not resistant to inorganic acid corrosion, and unstable in acetic acid and formic acid.

1. Chemical composition, N4 C content is less than 0.02% N6 C content is less than 0.15%, and the content of other elements is the same;
