Stainless steel is well-known for its corrosion resistance. More information on the corrosion properties of stainless steels can be found here.
Webinars: Understanding corrosion
Material decay and corrosion are natural processes. Almost all materials will in one way or another decay over time. The effects of corrosion in our daily lives can be seen both in our households, but also in the infrastructure we use to e.g. travel from home to work or school and in the industrial facilities that produce what we need to have comfortable and healthy lives.
Even materials, which we believe to be resistant to corrosion like stainless steels, do corrode in certain circumstances. To protect materials from corrosion we first have to understand why it occurs after which we can find solutions to avoid it as much as possible.
Avoiding corrosion means we can save costs and in extreme situations even save lives.

Introduction to corrosion resistance of stainless steels
The corrosion resistance of stainless steel arises from a “passive”, chromium-rich, oxide film that forms naturally on the surface of the steel. The mechanisms of corrosion include crevice corrosion, pitting corrosion, intercystalline (or intergranular) corrosion (ICC), stress corrosion cracking (SCC) and galvanic (bi-metallic) corrosion and are often associated with chlorides or acid conditions.

Stainless steel in contact with other metallic materials
Complex design requirements can make it necessary to combine different metallic materials within the same component. Also, chance combinations can often be found, governed only by the availability of, for instance, fasteners or shims. In certain circumstances, such mixed-material designs can lead to corrosion in one of the partner materials. This phenomenon includes galvanic corrosion, in which two different metals form a galvanic couple.
The present publication describes the principles of galvanic corrosion and the main parameters that allow designers to estimate corrosion risk.

Deicing Salt - Recognizing the Corrosion Threat
Many designers are not aware that deicing salt is very corrosive to architectural materials, and inadequate knowledge can lead to inappropriate material selection and premature failure.
This article discusses the impact of deicing salt on architectural materials and has an in-depth discussion of the relative performance of competitive materials.

Corrosion resistance of stainless steels in soils and in concrete
Corrosion by soil is a complex phenomenon due to the great number of variables involved. In principle, stainless steels should be in the passive state in soils, but the presence of water and aggressive chemical species such as chloride ions, sulphates and as well as types of bacteria and stray current, can cause localised corrosion.
