Alloy 200

Description

   DOWNLOAD LINE CARD

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
