Effect of Chlorine on Common Materials in Fresh Water

Long term corrosion data for common alloy materials from test spool exposures in chlorinated fresh water are reported. Data from the published literature on the effect of chlorine in fresh water on materials are reviewed. Experience with the high initial dosages used to sterilize potable water systems is reported. As a biocide and an oxidant, chlorine has other and secondary effects on corrosion behavior. Case histories of several of these are reported. Guidelines for alloy usage are developed.
