Specification of nickel 201

The chemical composition of Nickel 201 typically includes:

• Nickel (Ni): 99.0% minimum
• Carbon (C): 0.02% maximum
• Manganese (Mn): 0.35% maximum
• Iron (Fe): 0.40% maximum
• Silicon (Si): 0.35% maximum
• Copper (Cu): 0.25% maximum
• Sulfur (S): 0.01% maximum

Trace amounts of other elements may also be present depending on the specific production process.

Here are some mechanical properties of Nickel 201:

• Tensile strength: 60 ksi (414 MPa)
• Yield strength: 15 ksi (103 MPa)
• Elongation: 45%

Note that these values may vary depending on the specific form and heat treatment of the Nickel 201 material. It’s always important to consult the manufacturer’s data sheet for specific mechanical properties.

Performance of nickel 201

Nickel 201 has good welding performance and can be welded using various welding methods such as gas tungsten arc welding (GTAW/TIG), gas metal arc welding (GMAW/MIG), shielded metal arc welding (SMAW), and submerged arc welding (SAW). Welding procedures for Nickel 201 should follow the guidelines of the American Welding Society (AWS) and the manufacturer’s recommendations to ensure the best results. It is important to note that Nickel 201 has a low thermal conductivity and high coefficient of expansion, so proper preheating and post-weld heat treatment should be employed to prevent distortion or cracking.

Nickel 201 is a ferromagnetic material, which means it is attracted to a magnet and can be magnetized. However, its magnetic properties are relatively weak compared to other ferromagnetic materials. Nickel 201 exhibits a maximum magnetic permeability of around 400 at room temperature, which is lower than that of nickel alloys such as Inconel and Hastelloy. This makes Nickel 201 a suitable material for certain applications where magnetic interference must be minimized, such as in some electronic devices.

Nickel 201 is highly corrosion-resistant, especially in reducing environments. It has excellent resistance to corrosion by alkaline solutions, neutral and alkaline salts, and organic acids. Nickel 201 is also resistant to corrosion in pure water and in some reducing acids. However, it may be susceptible to corrosion in some oxidizing acids and halides. Overall, Nickel 201 is a versatile and reliable material for use in corrosive environments, such as those found in chlor alkali plants.
