A seal ring for a seal assembly includes a body and a seal flange. The body is generally cylindrical and extends along a longitudinal axis between a load end and a seal end. The seal flange is disposed adjacent the seal end of the body. The seal flange projects radially in circumscribing manner from the body to an outer perimeter thereof. The seal flange includes a sealing face having a sealing band, disposed adjacent the outer perimeter of the seal flange, and an inner relieved area, disposed between the sealing band and an inner perimeter of the seal flange. The sealing band is polished by an isotropic finishing process after a layer of coating composition is applied to at least the body. The layer of coating composition is formulated to withstand the isotropic finishing process and to help increase the corrosion resistance of the seal ring.
