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
