The need to place electrical equipment within corrosive environments necessitates protection beyond which painted carbon steel enclosures can provide. Enclosures made of stainless steel fill this void with superior strength and corrosion resistant properties. However, there are common criteria that must be considered to ensure that the proper stainless steel enclosure is chosen. This paper discusses some of the technical aspects of stainless steel that are crucial to the selection of industrial enclosures including composition, distinguishing properties of different grades, chemical resistances, suitable applications and general benefits offered by stainless steel when compared to painted carbon steel enclosures.
