A versatile and extremely important metallic material, widely used in industry because of its good strength and plastic toughness, pure nickel is used individually as a corrosion-resistant structural and functional material because of its good properties, in addition to forming valuable alloys with other metals. In practice, pure nickel used as a corrosion-resistant structural material is a nickel-carbon alloy containing carbon.

Mainly used in the Treatment of reducing halogenated gases, alkali solutions, non-oxidizing salts, organic acids and other equipment and components, in use the temperature should be lower than 315 degrees of the environment. Alloy corrosion resistance in the atmosphere corrosion is very slow, in seawater and all kinds of hydrochloric acid HCl has good corrosion resistance, but in the high flow rate of HIC acid to be used with caution, its H3 PO4 and HNO3 does not have availability, in H2SO4 can only be used for H2SO4 does not pass through the air in the H2SO4 in the high-temperature anhydrous HF has a very good corrosion resistance in high-temperature chlorine and HCl has a good corrosion resistance in chlorine and fluorine gas has a good corrosion resistance. Good corrosion resistance in chlorine and fluorine gas.
