What can be used to remove corrosion from highly stressed steel surfaces?

Fine-grit aluminum oxide is an effective choice for removing corrosion from highly stressed steel surfaces because it provides a controlled and gentle abrasive action. This type of abrasive helps to effectively remove rust and corrosion without causing significant damage or stress to the underlying steel. Unlike coarser materials, fine-grit aluminum oxide allows for a smoother finish and minimizes the risk of introducing new surface defects or altering the mechanical properties of the steel, which is crucial in highly stressed applications.

In contrast, chemical cleaners may not be suitable for all types of corrosion and might leave residues that could negatively affect the surface integrity. Sandpaper, depending on its coarseness, can cause excessive removal of material, which is undesirable for highly stressed components. Wire brushes, while effective for certain applications, can be too aggressive and may result in surface damage or cold working of the material, potentially leading to stress concentrations that could compromise the part's performance.
