 (a) Scanning electron microscopy (SEM) image and elemental maps obtained by energy-dispersive X-ray spectroscopy of MnS inclusions on a smooth stainless steel surface. (b) SEM image and elemental maps of MnS inclusions on a stainless steel surface subjected to rough grinding. The MnS inclusions are deformed by grinding, with cracks and partial embedding into the steel matrix observed. Pitting corrosion is observed at locations where grinding scratches intersect with MnS inclusions.
