In this article, we will take an in-depth look at Nickel 201's chemical composition, mechanical properties, areas of application, as well as its strengths and limitations in practice.

Chemical composition and physical properties of Nickel 201

1. Chemical composition

Nickel 201 Nickel Bar is a pure nickel alloy with low carbon content, the main component is nickel with a content of about 99.6% or more. The difference between Nickel 201 and Nickel 200 is that Nickel 201 has a much lower carbon content, typically no more than 0.02%. This feature makes Nickel 201 less susceptible to graphitization at elevated temperatures, which enhances its corrosion resistance.

The specific chemical composition of Nickel 201 is approximately as follows:

• Nickel (Ni): 99.0%-99.6
• Iron (Fe): 0.40% max.
• Carbon (C): 0.02% maximum
• Silicon (Si): up to 0.35%
• Manganese (Mn): max. 0.35
• Sulfur (S): up to 0.01%

This composition ratio gives Nickel 201 excellent chemical stability, especially when handling corrosive environments and chemical reagents.

2. Physical properties

Nickel 201 is also notable for its physical properties:

• Density: 8.89 g/cm³
• Melting point: 1435°C
• Resistivity: 9.5 μΩ-cm (at 20°C)
• Thermal conductivity: 67.3 W/m-K
• Coefficient of linear expansion: 13.3 μm/m-K (at 20°C - 300°C)

Nickel 201's stability at elevated temperatures and low resistivity make it ideal for use in high temperature or highly corrosive electrochemical environments.

Mechanical Properties and Processing Characteristics of Nickel 201

1. Mechanical Properties

The mechanical properties of Nickel 201 are characterized by good ductility and high tensile strength. Specific mechanical properties are listed below:

• Tensile strength: 380 MPa (in annealed condition)
• Yield strength: 100 MPa
• Elongation: 55%.

Its high ductility and low yield strength give Nickel 201 good formability at high temperatures, making it suitable for machining complex shapes. The high tensile strength means that the material is able to withstand a certain amount of mechanical stress, especially important when used in extreme environments.

2. Machining and welding properties

The low carbon content of Nickel 201 not only increases its resistance to graphitization at high temperatures, but also gives it excellent welding properties. Whether it is gas shielded, arc or resistance welding, Nickel 201 is well suited to these processes.

In terms of processing, Nickel 201 can be molded through common cold working and hot working processes. Cold working increases its hardness and strength, while hot working helps to reduce internal stresses in the material and improve its toughness. With proper heat treatment, Nickel 201 also maintains its chemical stability for more complex industrial needs.
