After experimental testing, it can be concluded that nickel200 has excellent chemical stability, high corrosion resistance, high temperature strength, excellent electrical conductivity and magnetic properties. In different application areas, different material processing forms can be selected to meet different needs.
Difference Between Casting and Forging
Casting is the pouring of molten metal material into a mold for molding, which can create complex shapes. Whereas, forging is the process of heating a metal material and then pressing and shaping it on a forging press, which can create a stronger material.
Smelting process
The smelting process of Nickel 200 mainly includes electric arc furnace and electric furnace melting. Electric arc furnace melting is the reaction of nickel200 with an oxidizer to produce a high-temperature flame to melt it. Electric furnace melting is in which nickel 200 is placed in an electrode and the material is melted by heating it with an electric current. In the smelting process, attention needs to be paid to controlling the composition of the alloy to ensure its quality.
Cold-rolled, hot-rolled and cold-drawn
Cold rolling is the pressing of nickel 200 at room temperature, which can produce high-precision plates, strips, etc. Hot rolling is to heat nickel 200 to a certain temperature and then press, which can make large-size plates, strips, etc. Cold drawing is the tensile deformation of nickel 200 at room temperature, which can produce high-precision seamless pipes, wires, etc.
Electroslag and electric furnace processing
Electroslag machining is a processing method in which an electrode is placed on top of a material, and the material is melted and fused with the electrode by means of an electric current. Electric furnace processing is in which the material is placed in an electrode and the material is heated by an electric current. Both processing methods can create complex shapes and are suitable for the manufacture of metal materials such as nickel 200.
Conclusion
Nickel200 is a metal material with excellent properties, which is widely used in chemical, electronics, aerospace, marine and other fields.
