Corrosion damages of high-alloy "stainless" steels structures

High alloyed corrosion resistant Cr-Ni stainless steels are, as it is well known and confirmed by countless examples of their successful application over the last hundred years, a unique kind of materials with extraordinary corrosion resistance properties in many different media. Without these steels, many modern industrial fields would be unthinkable. However, these steels are not, contrary to their name in almost all world languages, absolutely immune to various corrosion processes, especially not to localized corrosion. In this paper, from a practical point of view, an overview of the various stainless steel corrosion failures caused by pitting corrosion, crevice corrosion, stress corrosion cracking and microbiologically influenced corrosion is presented, as well as possibilities of their avoidance based on the conducted failure analysis investigations.
