Abstract
SE PROPORCIONA UNA LAMINA Y BARRA DE ACERO DE ELEVADA DUREZA, ALTA RESISTENCIA Y COSTE RELATIVAMENTE BAJO, QUE ES SUSTANCIALMENTE NO SUSCEPTIBLE DE DEFORMACION POR GOLPES EN LA SUPERFICIE IMPEDIDA EN LA CONDICION DE LAMINADO, Y SU METODO DE OBTENCION, SIENDO COMO SIGUE LA COMPOSICION DEL ACERO EN PORCENTAJE EN MASA RESPECTO A LA MASA BASE: C = 0,21-0,28; MN =0,80-1,80; CR = 1,60-2,10; SI = 0,35 MAXIMO; AL = 0,02-0,05; P Y S = 0,025 MAXIMO CADA UNO; FE = EL RESTO; ESTANDO CARACTERIZADO EL ACERO PORQUE SU COMPOSICION ES TAL QUE, POR ENFRIAMIENTO AL AIRE, SEGUIDO DE LAMINADO, LA TEMPERATURA DE TRANSICION DEL ACERO DURANTE EL ENFRIAMIENTO ES A UN NIVEL SUFICIENTEMENTE ALTO PARA ASEGURAR QUE HAY SUFICIENTE CONTRACCION TERMICA POSIBLE DESPUES QUE LA TRANSFORMACION SE HA COMPLETADO PARA SOPORTAR POR LO MENOS LA EXPANSION TERMICA QUE HA TENIDO LUGAR DURANTE LA TRANSFORMACION.
