Nickel 200

┃ Material

Nickel 200, UNS N02200, W.Nr. 2.4060 (Ni99.6), 2.4066(Ni99.2, N6

┃ Overview

Nickel 200 is commercially pure (99.0%) wrought nickel. It has good mechanical properties and excellent resistance to many corrosive environments. Other useful features of the alloy are its magnetic and magnetostrictive properties, high thermal and electrical conductivities, low gas content and low vapor pressure.

┃ Characteristics

Nickel 200 is characterized by:

(1) Excellent resistance in alkaline media

(2) High ductility in a wide temperature range

(3) Ferromagnetism

(4) High electrical and thermal conductivity

┃ Application

The corrosion resistance of Nickel 200 makes it particularly useful for maintaining product purity in the handling of foods, synthetic fibers, and caustic alkalies; and also in structural applications where resistance to corrosion is a prime consideration.

Other applications include chemical shipping drums, electrical and electronic parts, aerospace and missile components.

┃ Typical Mechanical Properties (as per ASTM B161)

┃ Corrosion resistance

Nickel 200 is highly resistant to many corrosive media. Although most useful in reducing environments, it can be used also under oxidizing conditions that cause the development of a passive oxide film. The outstanding resistance of Nickel 200 to caustics is based on this type of protection.

In all environments, when temperatures above 600°F (315°C) are involved, the preferred material is Nickel 201.

┃ Available Process

(1) Hot formed, annealed, descaled
