WebAug 25, 2024 · The Armor of Chromium Oxide In stainless steel, chromium forms a thin coating of chromium oxide on the surface, which prevents corrosion. This self-healing, … 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. A quick touch with a grinding wheel … See more While metal artists and hobbyists might be attracted by the heat tint generated during welding, those colors send signals to the fabricator about how much oxidation took place during the weld. Heat tints occur because the oxygen … See more Of course, the color on the front of a joint is only half the story. Failing to shield the back side of a stainless steel weld can cause “sugaring,” an extreme amount of oxidation that looks … See more interstitial disease in lungs symptoms
