ALLOY 200 (UNS No.N02200, DIN W.Nr. 2.4066)
Nickel 200 is commercially pure (99.6%) 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.
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 and rocket motor cases.
Alloy 200 is technically pure nickel with good mechanical properties and excellent resistance to alkali hydroxides as well as organic compositions. Even when exposed to high temperature. Alloy 200 retain its strength and is ductile at low temperature. Alloy 200 is a multipurpose grade and is used in application where alloys are not essential. It also has good magnetic and magnetostrictive properties, high thermal and electrical conductivity as well as low gas content in the electronics industry. Furthermore Alloy 200 is of interest for its good weld ability. |
