Abstract

Un producto plano de acero de acuerdo con la invención que posee no solo propiedades mecánicas óptimas, tales como una elevada resistencia y al mismo tiempo una buena tenacidad, sino que presenta también una buena idoneidad para la soldadura, presenta en el estado laminado en caliente una estructura sin ferrita que está compuesta en = 95 % en volumen por martensita y bainita con una proporción de martensita = 5 % en volumen y en total = 5 % en volumen de austenita residual así como componentes estructurales inevitables debido a la fabricación. Aparte de Fe e impurezas inevitables, el producto plano de acero de acuerdo con la invención contiene (en % en peso) además el 0.08 - 0.10 % de C, el 0.015 - 0.50 % de Si, el 1.20 - 2.00 % de Mn, el 0.020 - 0.040 % de Al, el 0.30 - 1.00 % de Cr, el 0.20 - 0.30 % de Mo, el 0.020 - 0.030 % de Nb, el 0.0015 - 0.0025 % de B, hasta el 0.025 % de P, hasta el 0.010 % de S, hasta el 0.006 % de N, en particular el 0.001 - 0.006 % de N. Entre las impurezas se encuentran hasta el 0.12 % de Cu, hasta el 0.090 % de Ni, hasta el 0.0030 % de Ti, hasta el 0.009 % de V, hasta el 0.0090 % de Co, hasta el 0.004 % de Sb y hasta el 0.0009 % de W. La invención proporciona, adicionalmente, un procedimiento con el que se puede fabricar de manera fiable y con una menor complejidad un producto plano de acero de acuerdo con la invención.
