Stainless steel (also known as inox) is a steel alloy with a higher chromium content, more resistant to corrosion and staining, but contrary to its name, it is susceptible to corrosion, especially under low-oxygen, high salinity or non-ventilated conditions. The chromium oxide forms a passive layer that inhibits/decreases the further corrosion of the surface, and prevents rust from penetrating into the inner layers of the steel.
