Chlorine ions are present in stainless steel use environment

Chloride ions exist widely, such as salt/sweat/sea water/sea breeze/soil and so on. Stainless steel in the presence of chloride ions in the environment, corrosion quickly, even more than ordinary mild steel. Therefore, there are requirements for the use of stainless steel environment, and it is necessary to wipe frequently, remove dust, and keep clean and dry. (That would give him a "misuse" designation.) There is an example in the United States: a company with an oak container containing a chloride ion solution, the container has been used for more than 100 years, the last century in the 1990s to replace, because the oak material is not modern enough, the use of stainless steel replacement 16 days after the container due to corrosion leakage.
