Passivation of Stainless Steel: What is It, and How Does It Work?

WebDec 27, 2024 · Besides the protective chromium layer, the other reason why stainless steel doesn’t rust or get tarnished easily has to do with the fact that stainless steel develops an oxide layer when it gets exposed to the air.This oxide layer protects the metal for corrosion. The interesting bit is that the oxide layer/ film will also develop after the … Chromium oxide forms immediately when the chromium atoms in stainless steel are exposed to oxygen in the atmosphere. As a general rule, all stainless weldments require postweld cleaning to ensure that a surface’s chrome-oxide film is intact. Otherwise, the weld area is subject to rusting. See more First, let’s look at carbon steel. When exposed to moisture, the iron in carbon steel reacts with oxygen to slowly form a reddish iron oxide.
