Abstract

Verwendung einer Stahllegierung, die in Massenanteilen aus Kohlenstoff (C) 0,06 - 0,15 Silizium (Si) 1,0 - 2,0 Mangan 0,7 - 2,2 Chrom (Cr) 0,1 - 0,8 Molybdän (Mo) 0,2 oder weniger Aluminium (Al) 0,1 oder weniger Vanadium (V) 0,2 oder weniger Stickstoff (N) 0,02 oder weniger Niob (Nb) 0,06 oder weniger Kupfer (Cu) 0,2 oder weniger Nickel (Ni) 0,2 oder weniger Bor (B) 0,001 - 0,004 Titan (Ti) 0,001 - 0,05 Wolfram (W) 0,2 oder weniger
und Eisen sowie erschmelzungsbedingter Verunreinigungen als Rest besteht wobei die Summe von Silizium (Si) + Mangan (Mn) + Chrom (Cr) + Kupfer (Cu) in einem Bereich von 3 bis 4 % liegt, und wobei die Stahllegierung ein feines, weitgehend perlitfreies, mehrphasiges Gefüge bestehend aus Ferrit mit eingelagertem Bainit sowie Martensit mit Restaustenit aufweist, wobei das Produkt aus Bruchfestigkeit und Bruchdehnung 20.000 [MPa*%] übersteigt, wobei die Festigkeit Rm im unverformten Zustand mehr als 600 MPa beträgt zur Herstellung von Stahlrohren hoher Festigkeit mit guter Umformbarkeit.
