What is Hot Rolling? Definition from Corrosionpedia

Scale is produced when the hot surface is oxidized by air. This mill scale can reduce corrosion if steel is exposed to air over short periods, however, the corrosion increases if exposed for long periods. Large amounts of mill scale also cause severe pitting corrosion if the surface is in contact with water.
