Hard Chrome Data for Corrosion Resistance

The following table is a general indication of the electroplating resistance of hard chrome to various corrosive agents. The corrosiveresistance of hard chrome in actual use is affected by operatingfactors, such as temperature, concentration, aeration and the presence of other constituents in the corrosive medium. As a result, the electroplating hard chrome data in this table must be considered only anapproximation. For critical conditions it may be preferable to conduct a test in the actual solution in use and under the actual operatingconditions.

Also note:

  • "C" indicates behavior at approximately 55°F
  • "H" indicates behavior at approximately 135°F
  • Except where otherwise noted results are given for 10% solutions of the chemical in water.
