Corrosion Resistance

General Corrosion Resistance:

  • Good Resistance to Alkaline Solutions: Nickel 200 excels in environments with alkaline substances, including strong bases like sodium hydroxide and potassium hydroxide.
  • Neutral and Mildly Acidic Environments: It performs well in neutral and mildly acidic conditions, including water and steam. It is also suitable for some organic acids at moderate concentrations.
  • Limited Resistance to Strong Acids: Nickel 200 has limited resistance to strong acids such as concentrated hydrochloric acid and hydrofluoric acid. It can suffer from corrosion under these conditions, especially at higher temperatures.

Specific Environments:

  • Sea Water: Provides reasonable resistance to seawater but may not be the best choice for marine applications due to better alternatives.
  • High-Temperature Applications: Effective up to about 600°C (1112°F), beyond which its oxidation resistance and mechanical properties may degrade.
  • Sulfuric Acid: Generally not recommended for use in concentrated sulfuric acid due to susceptibility to corrosion.

Additional Notes:

  • Stress-Corrosion Cracking: Nickel 200 is resistant to stress-corrosion cracking in many environments, which is a common issue in other materials.
  • Oxidation: It shows good resistance to oxidation, making it suitable for use in environments where exposure to air and high temperatures occurs.

Fabrication Data

  • Machinability: Nickel 200 is generally considered to be machinable, though it can work-harden during machining, so using sharp tools and appropriate cutting conditions is recommended.
  • Welding: It is weldable using most common methods, such as TIG, MIG, and resistance welding. Proper cleaning and handling are necessary to avoid contamination.
  • Formability: The alloy has good ductility and can be cold worked and formed into various shapes, including sheets, plates, and tubes.
  • Annealing: Annealing is often used to relieve stresses and to restore ductility after cold working. Typical annealing temperatures range from 800°C to 1000°C (1470°F to 1830°F).
