Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Stahlflachprodukts aus einem mittelmanganhaltigen Stahl mit TRI P/TW IP-Effekt. Um eine Verbesserung der Streckgrenze bei Erhalt eines ausreichenden Restumformvermögens des hergestellten Stahlflachprodukts zu erreichen, werden die folgenden Schritte vorgeschlagen: - Kaltwalzen eines Warm- oder Kaltbands, - Glühen des kaltgewalzten Warm- oder Kaltbands bei 500 bis 840 °C für 1 min. bis 24 h, - Nachwalzen oder Dressieren des geglühten Warm- oder Kaltbands zu einem Stahlflachprodukt mit einem Umformgrad zwischen 0,3 % und 60 %. Auch betrifft die Erfindung ein nach diesem Verfahren hergestelltes Stahlflachprodukt und eine Verwendung hierfür.
