Rouging of stainless steel in high purity water systems

Rouging is sometimes found in high purity hot water systems, usually appearing as a thin red or black powdery or 'slimy' deposit. The mechanism that causes rouging does not appear to be fully understood, but is connected to destabilization of the passive layer. Measures that improve corrosion resistance can help prevent rouging.

Selection of stainless steels in water supply and waste water treatment

Stainless steel grades, such as the 304 or 316 types are generally suitable for storing and handling cold or unheated drinking (town's) waters. Localised corrosion by crevice or pitting mechanisms is not usually a hazard in properly designed, fabricated and finished tanks handling clean waters of drinking quality.
