Nickel's knowledge

Pure nickel N6, high temperature atmosphere can lead to special corrosive environment. If there is significant water vapor, more corrosive conditions will occur.

The combination of high-temperature atmosphere and significant water vapor is common in energy producing equipment, for example, in gas turbines, steam turbines and fuel cells, as well as in heat exchangers and heat accumulators that process the gas vapor used or produced by such energy producing equipment, and in equipment that processes, processes, or extracts chemicals or minerals at high temperatures. Thus, pure nickel N6, the components of the apparatus subjected to these conditions, are made of various austenitic stainless steels.

Pure nickel has excellent conductivity and corrosion resistance, and its melting point is high. It will evaporate within the working temperature range of the cathode; It has satisfactory thermal evaporation and good machinability and formability; It has a good effect on the emissivity of the cathode, and has a suitable resistance coefficient, good radiation coefficient and large thermal conductivity. Therefore, it is mostly used for corrosion-resistant components. Important parts of precision instrument structure and equipment, such as filter screen (cloth) used for chemical corrosion-resistant equipment, strong alkali production, welding rod core wire for pig iron welding, lamp pin lead wire for bulb factory, heating rod lead wire, etc. N6, also known as No. 6 nickel, is a kind of pure nickel. In addition to the physical and chemical characteristics of metallic nickel, No. 6 nickel is also resistant to strong alkali, neutral and weak acid, and has stable performance in the atmosphere, fresh water and sea water. The main products are divided into hard products (without heat treatment) and soft products (after heat treatment), which are supplied according to the user's requirements.
