It is a very pure nickel alloy and is often chosen for use in environments where It is a very pure nickel alloy and is often selected for use in environments with very high corrosion requirements.
- Nickel Alloy 201 is also a nickel alloy with a lower carbon content. It contains a minimum of 99.0% nickel, while the carbon content is limited to less than 0.02%. Compared to Nickel Alloy 200, Nickel Alloy 201 has a lower carbon content.
Mechanical properties
At room temperature, the mechanical properties of Ni200 and Ni201 are similar, both have good plasticity and toughness. However, at high temperatures, due to differences in composition and microstructure, the mechanical properties of the two will appear to have larger changes.
Physical Properties
- Nickel 200 is a non-magnetic alloy because it has a high purity of nickel.
- Nickel 201, although also a non-magnetic alloy, may be slightly magnetic at high temperatures due to its slightly higher carbon content than Nickel Alloy 200.
- Density: The density of Ni200 is close to that of pure nickel, about 8.9g/cm³, while the density of Ni201 is slightly higher than that of Ni200, about 8.95g/cm³.
- Melting point: due to the different composition, Ni200 and Ni201 melting point there are some differences. Ni200 melting point is higher, about 1455 ℃, while Ni201 melting point is slightly lower, about 1350 ℃.
- Thermal conductivity: Ni201’s thermal conductivity is better than Ni200 because it contains a certain amount of chromium, chromium can improve the thermal conductivity of the material.
Corrosion Resistance
- Ni200 and Ni201 have excellent caustic resistance and good electrical and magnetostrictive properties.
- Both have good corrosion resistance and are suitable for a wide range of reducing chemicals.
- Ni201 contains a certain amount of chromium, so its corrosion resistance is better than that of Ni200.In an oxidizing environment, Ni201 can form a dense oxide film on its surface, effectively resisting corrosion. In the reducing environment, the corrosion resistance of Ni201 is also improved due to the addition of chromium. However, it should be noted that in extreme environments such as high sulfur and high temperature, Ni201’s corrosion resistance may be affected.
Areas of Application
- Nickel 200 is typically used in environments with very high corrosion requirements.
- Nickel 201 is used in higher temperature applications such as the handling and manufacture of sodium hydroxide above 300°C, soap manufacture, viscose rayon manufacture, benzene, methane and ethane production, reactors and vessels, etc.
In summary, the choice to use nickel 200 or nickel 201 depends on the specific environment and conditions of use. Understanding the differences between these materials will help to utilize their advantages and provide more reliable support and security for industrial production.
