Elemental abundances of the hot metallic‐lined (Am) stars 60 Leo and 6 Lyr, with modest rotational velocities, are derived consistently with other studies in this series of papers. Both stars are found to show the Am phenomenon strongly, with nearly solar abundances of the light elements, overabundances of most Fe peak elements, and considerable overabundances of SrYZr, Ba and some rare earths. Ca is underabundant, while Sc is very underabundant.
