Abstract

Bei einem Verfahren zum Herstellen von Vormaterial, beispielsweise von Draht oder Stabmaterial wird ein Stahl mit 0,08 bis 0,25% Kohlenstoff, bis 1% Silizium, 0,5 bis 2,5% Mangan, bis 0,035% Phosphor, bis 0,055% Schwefel, 0,1 bis 1.5% Chrom, 0,1 bis 0,5% Molybdän, 0,2 bis 1,5% Nickel, bis 0,06% Aluminium, 0,0010 bis 0.0060% Bor, jeweils bis 0,040% Titan, Vanadium und Niob. bis 0,5% Kupfer und 0,010% Stickstoff durch Warmverformen und anschließendes Abkühlen an Luft auf ein martensitisch-bainitisches Gefüge eingestellt. Das auf diese Weise aus der Umformhitze hergestellte Vormaterial besitzt eine hohe Festigkeit und Zähigkeit; eine Wärmebehandlung zum Einstellen der mechanischen Eigenschaften ist daher nicht erforderlich.
