Abstract:

The recent advances in research of the relationship between the chloride ion and the corrosion of stainless steel in cooling water system are reviewed. The mechanism of chloride ion which result in pitting, crevice corrosion, stress-corrosion cracking of stainless steel in cooling water system, the chloride ion limits and other factors influencing the localized corrosion of stainless steel are discussed. At the same time, the comments on how to deal with the negative effects of chloride ion in cooling water are made.

Key words: chlorideion, cooling water, corrosion of stainless steel
