When scale is partially rolled into the surface of a steel plate it is called

Explanation:
When oxide scale forms on hot steel, it can sometimes get pressed back into the surface as the plate is formed. That embedded scale creates a rough, irregular finish and is called rolled-in scale. This term specifically describes scale that is partially embedded in the surface, rather than simply lying on top or creating a hole or crack. It’s different from pits (small surface cavities), tears (cracks in the material), or scabs (raised patches from surface delamination). Rolled-in scale affects surface finish and coating performance, and may require finishing to restore a smooth surface.
