The density of N02200 is 89g cm, the melting point is 1435, and the specific heat capacity is 0444 J g·K, thermal conductivity of 0909W m·k, resistivity 697 10 m, which is the first among metal materials, has excellent electrical conductivity.
2. Characteristics and mechanical properties of N02200
1.Corrosion resistance:N02200 has excellent corrosion resistance and can be used for a long time in extremely corrosive environments, such as strong acids, strong alkalis, hydrogen, etc. At the same time, the material also has good high temperature oxidation resistance, and can be used for a long time below 800.
2.Physical Properties:N02200 has high specific heat capacity, thermal conductivity and electrical conductivity, and it also has the characteristics of small thermal expansion coefficient, good fatigue resistance and low permeability.
3.Mechanical Properties:N02200 has good mechanical properties, high strength, good plasticity and toughness, and can be processed into plates, round bars, forgings, seamless pipes, forging rings and other forms by forging, rolling, stretching, etc.
3. The manufacturing process of N02200
The production process of N02200 has two methods: casting and forging, and the casting process is mainly divided into sand casting, sodium silicate sand casting, vapor phase fusion casting and other methods. Among them, fumed fusion casting is a relatively new production process, which can obtain N02200 material with high purity and good uniformity.
The forging process is mainly divided into two ways: hot forging and cold forging. Hot forging is to heat the metal to a certain temperature and then forge, which can obtain better processing performance and mechanical properties; Cold forging is forged at room temperature, which can obtain high strength and toughness, but the processing performance is poor. Annealing is also required during the forging process to eliminate residual stresses and improve the toughness of the material.
Fourth, the processing method of N02200
The processing methods of N02200 include cold rolling, hot rolling, cold drawing, electroslag processing and electric furnace processing. Among them, cold rolling is the processing of metal sheets or strips at room temperature to obtain high strength and toughness; Hot rolling is the process of heating metal sheets or strips to a certain temperature to obtain high ductility and plasticity. Cold drawing is the processing of metal pipes at room temperature, which can obtain high strength and toughness, but it is difficult to process. Electroslag machining and electric furnace machining are the processing of metal materials using high-temperature plasma or electric arc, which can achieve excellent corrosion resistance while cooling quickly.
V. Conclusions
N02200 is a metal material with excellent performance and a wide range of applications, which is widely used in chemical, electric power, aviation, aerospace and other fields due to its corrosion resistance, high temperature stability, electrical conductivity and other advantages.
