AMS 5553 - Nickel 201 Sheet and Strip
The AMS 5553 specification covers the SAE International standard for Nickel 201 sheet, strip, and tape products. Nickel 201, or UNS N02201, is a low carbon variation of Nickel 200. It was developed to enhance performance in high-temperature applications. Nickel 201 contains a maximum of 0.02% carbon. This ensures that there is no carbon precipitation that causes embrittlement at temperatures above 600°F or 315°C.
Nickel 201 provides excellent corrosion resistance, ductility, and thermal stability. It is used in chemical processing, the aerospace industry, and in the fabrication of pressure vessels. Nickel 201 provides high purity in reducing or neutral environments.
Properties of AMS 5553 Nickel 201
- High-temperature capability: Approved for use up to 1250°F (677°C)
- Excellent corrosion resistance: Performs well in acidic, alkaline, and salt solutions
- Low carbon content: Prevents intergranular embrittlement and graphite precipitation
- Excellent workability: Suitable for spinning, cold forming, and welding
- Stable mechanical properties: Maintains strength and ductility under cyclic thermal exposure
Applications of AMS 5553 Nickel 201
- Aerospace parts that must endure severe corrosive or extreme temperature conditions
- Pressure vessels and heat exchangers constructed to ASME Boiler and Pressure Vessel Code specifications
- Chemical processing equipment, tanks, pipes, and evaporators
- Marine and power generation equipment that require long-lasting oxidation resistance
Nickel 201 according to AMS 5553 specification is used to construct pressure vessels and parts that require exceptional purity and strength.
