Based on practical cases, tests and available literature the paper reviews the relation between
surface condition and corrosion properties of stainless steel used in breweries, dairies and
pharmaceutical processing plants. Aspects related to specification, corrosion testing and posttreatment
(e.g. pickling and passivation) are also discussed.
