Corrosion of stainless steel in food and pharmaceutical industry


Stainless steels are widely used in the food and pharmaceutical industry because of their high corrosion resistance and superior mechanical properties. These features are crucial because produced foodstuffs and drugs must comply with high purity and quality standards. Just a proper selection of stainless steel grade can prevent corrosion phenomena that can be detrimental to the whole manufacturing process. Food/drugs production process phases will be here analyzed and discussed with a particular emphasis on the possible corrosion mechanism of stainless steels in those particular operating conditions. Recent advances on the methods to assess corrosion of stainless steels in food and pharmaceutical industries will be disclosed.
