WebThe following conditions require external coatings on stainless steels to guard against external corrosion damage: Equipment buried underground, where wet soil with chlorides and microbes is in contact with stainless steel. Equipment submerged in wet pits, where salty water could be present and microbes are in contact with stainless steel. WebApr 1, 2024 · Because the chromium is the primary alloying element that makes stainless steel corrosion resistant, the chromium-depleted regions are susceptible to preferential corrosion attack. It is believed that this occurs because the chromium content immediately adjacent to the carbide may be below that required for the stainless steel alloy.

Case Study: How Chromium Protects Steel — UMich MSE
WebSep 12, 2024 · One way to prevent, or slow, corrosion is by coating the metal. Coating prevents water and oxygen from contacting the metal. Paint or other coatings will slow corrosion, but they are not effective once scratched. Zinc-plated or galvanized iron exploits the fact that zinc is more likely to oxidize than iron.
