Alloy 200

Last updated: November 30, 2018

What Does Alloy 200 Mean?

Alloy 200 is a pure commercial wrought nickel. This type of alloy exhibits excellent mechanical properties and resists many harsh corrosive environments.

The chemical composition of Alloy 200 is:

  • Nickel – a minimum of 99%
  • Copper – 0.25% max
  • Carbon – 0.15% max
  • Manganese – 0.35% max
  • Silicon – 0.35% max
  • Sulfur – 0.01% max
  • Iron – 0.4% max

Alloy 200 is also known as Nickel 200.

Corrosionpedia Explains Alloy 200

Alloy 200 exhibits excellent resistance to harsh corrosive media such as acids, caustic alkalis and mineral acids. It is much less resistant when exposed to oxidizing salts. It shows resistance to all dry gases at room temperature.

Some of the applications for Alloy 200 are:

  • Food production, such as the handling of cool brines, fatty acids and fruit juices.
  • Vessels in which fluorine is generated and reacted with hydrocarbons.
  • Storage and transportation of phenol-immunity from any form of attack ensures absolute product purity.
  • Manufacturing and handling sodium hydroxide, particularly at temperatures above 299 °C (570 °F).
  • Production of viscose rayon and soap because of its general corrosion resistance and virtual immunity to inter-granular attack above 315 °C (600 °F).
  • Production of hydrochloride and chlorination of hydrocarbons such as benzene, methane and ethane.
