Time:2022-03-20 Source:WUXI JIANUO SPECIAL STEEL CO.

Steel grade: UNS N02200

Characteristics and application areas.


* Commercially pure nickel (99.6%), a solid solution alloy with a face-centered cubic structure.

* Good mechanical properties and processing and forming properties.

* Excellent corrosion resistance in a wide range of corrosive environmental conditions.

wedding-8 2


* Used in clean production process equipment such as food, man-made fibers, and caustic soda.

* Widely used in structures and components for corrosive conditions, such as chemical delivery drums, electrical and electronic components, and parts for aerospace applications.

* Material is typically restricted to use below 600°F (315°C) due to graphitization of the product, resulting in a severe degradation of the product’s performance.
