Nickel 201（NO2201/2.4060）

Product Description:

Nickel 201 alloy is an alloy containing commercially pure wrought nickel with excellent mechanical properties and corrosion resistance, high thermal and electrical conductivity, low gas content and low vapor pressure.

Nickel 201 has similar properties to Nickel 200. However, due to its lower carbon content, Nickel 201 is better able to prevent the embrittlement of intergranular carbon at high temperatures.

Nickel 201 has the natural property of being highly resistant to corrosion in acids and alkalis. It is particularly useful under reducing conditions. The alloy has excellent caustic resistance, including in its molten state. The alloy shows good resistance to acids, alkalis and neutral salt solutions.

However, severe corrosion occurs when nickel 201 is in an oxide salt solution. Nickel 201 alloy is resistant to all dry gases at room temperature. In dry chlorine and hydrogen chloride, Nickel 201 alloy can be used at temperatures up to 550 °C. Its resistance to inorganic acids varies depending on temperature, concentration and solution aeration. Its corrosion resistance is better in degassed acid.

characteristic:

Nickel 201 has the excellent corrosion resistance characteristic of Nickel 200. Because it is a low-carbon material (0.02%max.), alloy 201 is not subject to embrittlement by intergranularly precipitated carbon or graphite when held at temperatures of 600° to 1400°F (315° to 760°C) for extended times, provided carbonaceous materials are not in contact with it. It is,therefore, preferred to Nickel 200 in all cases where temperatures exceed 600°F (315°C).

Nickel 201 is used for laboratory crucibles that must be capable of withstanding oxidizing furnace atmospheres up to

2000°F (1100°C).

The material is subject to inter-granular embrittlement by sulfur compounds at temperatures above 600°F (315°C)

Application areas:

Manufacturing and handling of sodium hydroxide, especially at temperatures above 300°C.

Production of viscose rayon. Manufacturing of Soap.

Production of aniline hydrochloride and in the chlorination of aliphatic hydrocarbons such as benzene, methane and ethane.

Manufacture of vinyl chloride monomer.

Reactors and vessels that produce fluorine and react with hydrocarbons.

Corrosion of evaporators, slats and electronic components

Form: 

Forgings, plates, rods, tubes, strips, wires, welding rods, etc.
