Environments such as marine (e.g., near coastlines with higher salinity), those with high industrial pollution loads, locations with atmospheric dirt from street traffic or construction sites, and locations where salt sprays are used for de-icing roads are environments not conducive to the proper formation of a protective layer on steel through passivation. In such environments, very frequent maintenance of the steel or the use of steel with higher chromium content, such as AISI316, is recommended.
