Alloy 200
Description
Alloy 200 is an unalloyed wrought nickel. It offers excellent corrosion resistance, good mechanical, magnetic and magnetostrictive properties and useful thermal and electrical conductivities.
Design Features
- Excellent resistance to many corrosive media from acid to alkaline.
- Extremely high resistance to caustic alkalis including the molten state.
- Resistance to mineral acids varies according to temperature and concentration and whether or not the solution is aerated. Corrosion resistance is better in non-aerated acids.
- In acid, alkaline and neutral salt solutions, Alloy 200 shows good resistance, however, severe attack occurs in oxidizing salt solutions.
- Resistant to all dry gases at room temperature.
Typical Applications
- Food production, such as the handling of cool brines, fatty acids and fruit juices
- Vessels in which fluorine is generated and reacted with hydrocarbons
- Storing and transportation of phenol - immunity from any form of attack ensures absolute product purity
- Manufacture and handling of sodium hydroxide, particularly at temperatures above 570°F
- Production of viscose rayon and manufacture of soap - general corrosion resistance and virtual immunity to intergranular attack above 600°F
- Production of hydrochloride and chlorination of hydrocarbons such as benzene, methane and ethane
