Abstract (de)
Die Erfindung bezieht sich auf eine Warmarbeitsstahl-Legierung, enthaltend die Elemente Kohlenstoff (C), Silicium (Si), Mangan (Mn), Chrom (Cr), Molybdän (Mo), Vanadin (V), Stickstoff (N) und Verunreinigungselemente sowie Eisen als Rest. Um bei einer thermischen Vergütung eine hohe Härte und eine verbesserte Zähigkeit des Werkstoffes auch bei niedrigen Abkühlraten zu erreichen, ist erfindungsgemäß vorgesehen, dass die Legierungselemente Gehalte in Gew.-% von aufweisen.
