A method is provided for Steckel mill rolling and finishing flat rolled steel having uniform mechanical properties, good surface quality, and ease of flattening whether in coil form or discrete sheet or plate by hot rolling a heat ed transfer bar in a Steckel mill and reverse rolling and optional coiling to achie ve finished flat rolled product of a selected thickness and selected austenite finishing temperature. The finished product is water cooled to a ferrite transformation temperature and thereafter air cooled until transformation from austenite to ferrite is at least 70% completed. The product may be further water cooled to a temperature below the ferrite transformation temperature.
