• The following is a list of applications for Nickel 200 alloy:
• Synthetic fiber
• Food processing equipment
• Barrels transporting chemicals
• Rocket engine
• Piping and equipment for use with alkalis
• Food handling
• Aerospace and Missile Components

 

 

Corrosion resistant in a wide range of marine and chemical environments. From pure water to non-oxidizing inorganic acids, salts and bases.

This alloy is more resistant to nickel under reducing conditions than copper, and more resistant to corrosion than copper under oxidizing conditions, but it does show better resistance to reducing media than under oxidizing conditions.

Good mechanical properties from sub-zero temperatures to about 480C.

Has good resistance to sulfuric acid and hydrofluoric acid. However, aeration can lead to increased corrosion rates. Can be used to treat hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosion.

Resistant to neutral, alkaline and acidic salts, but less resistant to oxidizing acid salts such as ferric chloride.

Excellent resistance to chloride ion stress corrosion cracking.
