FLEJE DE ACERO LAMINADO EN CALIENTE, QUE TIENE UNA COMPOSICIÓN QUE COMPRENDE MÁS QUE 0,25 HASTA 1,1% DE C, DE 0,5 A 2,0% DE MN, DE 0,05 A 0,50% DE SI, Y MENOS DE 0,01% DE AL; Y MÉTODO DE FABRICACIÓN QUE COMPRENDE ENROLLAR EL FLEJE EN CALIENTE A UNA TEMPERATURA ESPECIFICADA PARA SUMINISTRAR UNA MICROESTRUCTURA DESEADA. A hot rolled steel strip made by the steps including assembling a twin roll caster, forming a casting pool of molten steel of such composition that the cast strip produced comprises by weight, greater than 0.25% and up to 1.1% carbon, between 0.40 and 2.0% manganese, between 0.05 and 0.50% silicon, less than 0.01% aluminum, counter rotating the casting rolls to solidify metal shells and forming a steel strip, hot rolling the steel strip such that mechanical properties at 10% and 35% reduction are within 10% for yield strength, tensile strength and total elongation, and coiling the hot rolled steel strip at a temperature between 550 and 750° C. to provide a majority of the microstructure comprising pearlite, along with bainite and acicular ferrite. The steel may have a free oxygen content between 5 and 50 ppm or between 25 and 45 ppm.
