Carbon steel is heated to approximately 55C above the AC3 for a minimum of 1 hour. This assures that the steel completely transforms to austenite. The steel is then cooled with an approximate rate of 38C per minute. This results in a fine pearlitic structure and a more uniform structure. Normalized steel generally has a higher strength than a fully annealed product but good strength and ductility
