The protective layer on stainless steel consists of 3-4 chromium oxide atoms, which forms instantly when chromium reacts with oxygen. This layer is not easily removed; instead, it regenerates within nanoseconds after being disturbed. The rapid formation of this chromium oxide layer is crucial for maintaining the corrosion resistance of stainless steel, similar to the behavior observed in aluminum.
PREREQUISITESMaterials scientists, engineers, and anyone involved in the manufacturing or maintenance of stainless steel products will benefit from this discussion.
The chromium oxide layer forms on the stainless steel surface when chromium reacts with oxygen. This happens instantly, with formation speeds measured in nanoseconds [...]
