Nickel 201 vs. Nickel 200 Fasteners: Key Differences and Applications

Nickel fasteners are widely used in industries that need high strength, corrosion resistance, and durability. Two popular grades used in fasteners are Nickel 200 and Nickel 201. Both materials have similar properties but differ in a few important ways. Let’s explore the key differences and applications of Nickel 201 fasteners compared to Nickel 200 fasteners.

Key Differences Between Nickel 200 and Nickel 201 Fasteners

1. Composition

   • Nickel 200 is a commercially pure nickel (99.6% nickel) with low carbon content.

   • Nickel 201 has an even lower carbon content than Nickel 200, making it more resistant to embrittlement at high temperatures.

2. Temperature Resistance

   • Nickel 200 fasteners work well in temperatures up to 315°C.

   • Nickel 201 fasteners are designed for higher temperatures, performing better above 315°C without becoming brittle.

3. Mechanical Strength

   • Nickel 200 fasteners offer high mechanical strength and toughness.

   • Nickel 201 fasteners have slightly lower mechanical strength but are more stable at elevated temperatures.

4. Corrosion Resistance

   • Both grades resist corrosion, but Nickel 201 is better suited for handling strong acids and alkaline environments at high temperatures.

5. Electrical Conductivity

   • Both Nickel 200 and Nickel 201 fasteners have excellent electrical conductivity, but Nickel 201 is preferred for applications requiring better thermal stability.

Applications of Nickel 200 and Nickel 201 Fasteners

Nickel 200 Fasteners

• Used in chemical processing plants.

• Ideal for electrical and electronic components.

• Suitable for food processing equipment.

• Used in aerospace and marine applications.

Nickel 201 Fasteners

• Preferred in high-temperature chemical processing.

• Used in heat exchangers and furnace components.

• Common in electronics requiring high thermal stability.

• Ideal for alkali production and handling corrosive environments.

Choosing the Right Fastener

If your application involves moderate temperatures and high strength, Nickel 200 fasteners are a good choice. However, if you need fasteners for high-temperature environments with better stability, Nickel 201 fasteners are the better option.

Understanding the differences between these two materials can help you select the right fastener for your needs, ensuring long-term performance and reliability.
