Nickel material mechanical properties and physical properties

Nickel is one of the important strategic metals heavy non-ferrous metals. Nickel with corrosion resistance, heat resistance, high strength, plasticity, has been widely used in steelmaking,electroplating, alkali, electric vacuum, petroleum, chemical and other industrial sectors. In foreign countries, a long history of nickel smelting and processing, the variety specification is complete, theprocessing technology is mature, advanced technology.

Pure nickel iron group elements a silvery white, its high melting point, is 1453 degrees, strong corrosion resistance, in an oxidizing gas, the temperature is 1040 degrees, in a reducing atmosphere,the temperature is 1260 degrees.

As a result of nickel with excellent corrosion resistance in the high concentration of alkali and reducing medium, so at home and abroad are widely used as the main equipment of high concentrated alkaliproduction, especially there is nothing comparable to this on the concentration of IH GF 42% highconcentrated alkali corrosion resistance and other metal materials. So in recent years it in China'schlor-alkali production plays a very important role.
