Application and development trend of pure nickel 201 alloy in chemical industry
Pure Nickel 201 Overview
Pure Nickel 201 is a pure nickel alloy with extremely high purity. Its nickel content exceeds 99% and also contains trace amounts of carbon, manganese, silicon, iron, copper and other elements. It is similar to pure nickel 200, but has some other elements added to improve its corrosion resistance. Pure nickel 201 has excellent corrosion resistance, high temperature strength and good toughness. It is an important structural material and corrosion-resistant material.
The corrosion resistance of pure nickel 201 is one of its greatest features. It can show good corrosion resistance in various corrosive media such as strong acids, alkalis, salt solutions, oxidants and reducing agents. Pure nickel 201 can also work at high temperatures and has high thermal stability and excellent high-temperature strength. Therefore, it is widely used in high-temperature, high-pressure, and highly corrosive environments.
Pure nickel 201 also has good processability and weldability. It can be formed into materials of different shapes through various processing methods, such as forging, rolling, drawing, etc., and it can also be welded with other materials to form various complex structures.
The following are some physical and chemical properties of pure nickel 201:

Hardness: Approximately 65 HRB (at room temperature).
Corrosion performance: Pure nickel 201 has good corrosion resistance and can work stably in strong acids, strong alkali, salt water and high-temperature oxidizing atmospheres.
Pure nickel 201 with added copper has better corrosion resistance than pure nickel 200.
Magnetism: Pure Nickel 201 is a ferromagnetic material.
Processability: Pure nickel 201 can be processed into materials of different shapes through cold working, hot working, welding and casting.
Pure nickel 201 strip has wide application prospects due to its good corrosion resistance, high temperature performance and thermal stability.
Here is an overview of some applications of pure nickel 201 tape:
Chemical industry: Pure nickel 201 strips are widely used in equipment requiring corrosion resistance in the chemical industry, such as hydrogen chloride generators, acidic alkylation catalyst beds, heavy oil hydrogenation units, etc.
Petroleum industry: Pure nickel 201 strip is widely used in equipment that require corrosion resistance and high temperature resistance in the petroleum industry, such as distillers, catalyst beds, chemical reactors, etc.
Nuclear industry: Pure nickel 201 strip is widely used in the nuclear industry and can be used in components of nuclear reactors, nuclear fuel elements, accelerators, etc.
Food processing industry: Pure nickel 201 strip can also be used in the food processing industry, such as food equipment, candy stoves, etc.
In addition, pure nickel 201 strip can also be used in aviation, aerospace, electric power, electronics, shipbuilding and other fields.
Since pure nickel 201 strip is used in harsh environments such as high temperature and corrosion, it has the following special requirements:
High purity requirements: The purity is required to be higher than 99.5% to ensure its stability and reliability in high temperature and corrosive environments.
High precision requirements: When manufacturing pure nickel 201 strip, its size, surface quality and heat treatment parameters are required to meet precision requirements.
Board surface requirements: The surface is required to be smooth, without cracks, oil stains, defects, etc.
High strength requirements: Since pure nickel 201 strip is used in high temperature, high pressure, and highly corrosive environments, it is required to have good heat resistance, corrosion resistance, and high strength.
Pure Nickel 201 and 200 are both pure nickel alloys composed of more than 99% nickel. They are similar in many ways, but there are also some differences.
Corrosion resistance: Pure Nickel 201 has 0.5% copper added, which makes it more corrosion-resistant than Pure Nickel 200. Therefore, in strong alkali and oxidizing environments, the corrosion performance of pure nickel 201 is better than that of pure nickel 200.
Magnetism: Both pure nickel 201 and 200 are ferromagnetic materials, but the ferromagnetism of pure nickel 201 is slightly lower than that of pure nickel 200.
Processability: Due to the higher copper content of pure nickel 201, its plasticity and processability are slightly inferior to pure nickel 200.
Thermal stability: Due to the addition of copper to pure nickel 201, its thermal stability is slightly lower than that of pure nickel 200.
