Description
<Desc/Clms Page number 1>
Hitzebeständige Chrom-Aluminium-Silizium-Eisenlegierungen.
Die Erfindung betrifft hitzebeständige Chrom-Aluminium-Silizium-Eisenlegierungen, welche einen Gehalt von etwa 0'5 bis 2% Kohlenstoff, etwa 20 bis 25% Chrom, bis etwa je 2% Aluminium und Silizium und etwa 1 bis 5% Kupfer aufweisen.
Es hat sich überraschenderweise gezeigt, dass hiezu keine Einschmelzmaterialien von besonderem Reinheitsgrad erforderlich sind, wodurch eine sehr wirtschaftliche Erzeugung und ein weites Anwendungs- gebiet ermöglicht werden. Demgemäss können verschiedene Nebenbestandteile, wie insbesondere Phosphor und Schwefel, entsprechend der Verwendung billiger Einschmelzmaterialien vorhanden sein.
Es ist auch überraschend, dass ein höherer Kohlenstoffgehalt gegeben werden kann, obwohl dieser bei solchen Legierungen bisher als schädlich für hohen Korrosionswiderstand erachtet wurde. Er kann bis 2% betragen ; die Legierung kann bei Gehalten von 0'8 bis 2% Kohlenstoff leicht vergossen werden.
Ist hingegen Schmiedbarkeit erwünscht, so kann der Kohlenstoffgehalt bis 0'5% herabgesetzt werden.
Der Siliziumgehalt der Legierung könnte gegebenenfalls auch über 2% betragen ; bei höherem Ausmass, wie etwa 4 bis 6%, wird aber die Sprödigkeit merklich gesteigert.
Die Zusammensetzung der Legierung kann verschiedenen Eigenschaften, wie Formgebung, Widerstandsfähigkeit gegen oxydierende Einflüsse, Säuren usw., angepasst werden ; beispielsweise haben sich folgende Ausführungsformen sehr gut bewährt :

Heat-resistant chrome-aluminum-silicon-iron alloys.
The invention relates to heat-resistant chromium-aluminum-silicon-iron alloys which have a content of about 0.5 to 2% carbon, about 20 to 25% chromium, up to about 2% each of aluminum and silicon and about 1 to 5% copper.
It has surprisingly been found that no melt-in materials of a particular degree of purity are required for this, which enables very economical production and a wide range of applications. Accordingly, various secondary constituents, such as, in particular, phosphorus and sulfur, can be present in accordance with the use of cheap sealing materials.
It is also surprising that a higher carbon content can be given, although in such alloys this was previously considered detrimental to high corrosion resistance. It can be up to 2%; the alloy can easily be cast with a carbon content of 0.8 to 2%.
If, on the other hand, forgeability is desired, the carbon content can be reduced to 0.5%.
The silicon content of the alloy could possibly also be over 2%; at a higher level, such as about 4 to 6%, however, the brittleness is noticeably increased.
The composition of the alloy can be adapted to various properties, such as shape, resistance to oxidizing influences, acids, etc.; For example, the following embodiments have proven to be very effective:
