What forms of corrosion can occur on stainless steels? Corrosion
A plain carbon steel, with negligible corrosion resistance, would suffer from uniform or general corrosion across most of its surface. As stainless steels will form a passive protective layer when exposed to oxygen, corrosion will typically only occur when this passive layer becomes damaged or is missing. Therefore, pitting corrosion is the most common form of corrosion that can occur on stainless steels.
There are multiple different forms of corrosion, depending upon the corrosive environment, component geometry and operating conditions. These include crevice corrosion, erosion corrosion, intergranular corrosion, stress corrosion cracking and microbiologically induced corrosion.
