Which method may be used to remove corrosion from highly stressed steel surfaces?

Using fine grit aluminum oxide is a suitable method for removing corrosion from highly stressed steel surfaces because it provides an effective balance between abrasion and surface preservation. This method allows for the careful removal of corrosion without excessively compromising the integrity of the steel underneath. The fine grit ensures that while rust and corrosion are stripped away, it minimizes the risk of introducing new stress concentrations or surface irregularities which could potentially lead to fatigue failures in highly stressed areas.

Fine grit aluminum oxide is also beneficial as it creates a controlled surface profile, which can help in maintaining the overall strength and durability of the material. This is crucial in applications where steel components are subjected to significant loads.

Other options may not be as appropriate for this task. For instance, steel wire brushes may be too aggressive and can remove more material than desired, leading to surface damage and stress concentration. Medium grit paper might also be excessive for highly stressed surfaces, potentially altering the steel's properties or causing damage. Crocus cloth, while effective for polishing and finishing, may not adequately address corrosion removal in highly stressed areas, where a more robust approach is needed.
