Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Verbundwerkstoffes mit einer oder mehreren Chromstahlauflagen, deren Korrisionswiderstand einem Super-Ferrit entspricht, ausgehend von einem Verbundmaterial mit einem Trägerwerkstoff, dessen Chromstahlauflagen normale Kohlenstoffgehalte aufweisen, wobei die Trägerwerkstoffe mit karbid- und nitridbildenden Elementen, insbesondere Titan, legiert wird, das Verbundmaterial dann als Blech ausgewalzt und schließlich bei so hohen TemperaturenThe present invention relates to a method for Manufacture of a composite material with one or more chrome steel layers, their corrosion resistance corresponds to a super ferrite, based on a composite material with a carrier material, the chromium steel layers of which have normal carbon contents, whereby the carrier materials with carbide and nitride-forming elements, in particular titanium, is alloyed, the composite material then as sheet metal rolled out and eventually at such high temperatures

Ί und so langen Glühzeiten gearbeitet wird, bis der Kohlenstoffgehalt in den ferritischen Chromstahlauflagen auf Gehalte von 0,001 —0,003% reduziert wird, nach Patent 26 21 329.
Durch dieses Verfahren wird ein VerbundwerkstoffΊ and so long annealing times are worked until the carbon content in the ferritic chromium steel layers is reduced to contents of 0.001-0.003%, according to patent 26 21 329.
This process creates a composite

Aufgabe der vorliegenden Erfindung ist es, dieses Verfahren derart weiterzuentwicklen, daß die mechanischen Werkstoffeigenschaften des Träger- und Ay'agewerkstoffes verändert werden und das Kaltwalzen -Ό einschließlich der normalisierenden und rekristallisierenden Glühung erleichtert wird.The object of the present invention is to develop this method so that the mechanical Material properties of the carrier and Ay'a material be changed and cold rolling -Ό including normalizing and recrystallizing Annealing is facilitated.

Diese Aufgabe wird dadurch gelöst, daß das Verbundmaterial zunächst zu Warmband ausgewalzt wird, das der entkohlenden Glühung unterworfen wird, j wobei als Trägerwerkstoff eine C-Stahlqualität verwendet wird.This object is achieved in that the composite material is first rolled out to form hot strip which is subjected to the decarburizing annealing, j where a carbon steel quality is used as the carrier material will.

Auf diese Weise ergibt sich eine Erleichterung des Glühprozesses, da keine Rücksichtnahme auf oxidische Einflüsse und damit auf Verzunderungc.i der OberflächeThis makes the annealing process easier, since there is no consideration for oxidic Influences and thus on scaling.i of the surface

Normalerweise wird das Warmband kaltgewalzt, anschließend rekristallisierend geglüht und dressiert, um gute mechanische Eigenschaften zu erreichen.'"· After annealing, the hot strip can be in certain Cases are used in pickled and dressed form. Usually the hot strip is cold rolled, then annealed in a recrystallizing manner and tempered in order to achieve good mechanical properties reach.
