Description
Die Verwendung von Form-, Stab- oder Breiteisen, Blechen u. dgl. aus Chrom-Kupfer-Stahl Zusatz zum Patent 6o6 9.35 Zur Verwendung von Form-, Stab- oder Breiteisen, Blechen o. dgl. für Konstruktionsteile hochbeanspruchter Bauwerke sind Stähle gemäß dem Patent 6o6 935 vorgeschlagen worden, die bei einem Kohlenstoffgehalt von o, i bis o,2 % einen Kupfergehalt von o,6 bis i, 5 % und einen Chromgehalt von o,--5 bis o, 5 % besitzen.The use of shaped, bar or wide bars, sheets and the like made of chrome-copper steel Addition to patent 6o6 9.35 For the use of shaped, bar or wide bars, sheets or the like for structural parts of highly stressed buildings, steels are according to the patent 6o6 935 has been proposed, which have a carbon content of 0.1 to 0.2%, a copper content of 0.6 to 1.5% and a chromium content of 0.5 to 0.5%.
Gegenstand der .vorliegenden Erfindung ist ein Stahl, dessen Kohlenstoff- und Chromgehalt innerhalb der oben angegebenen Grenzen bleibt, dessen Kupfergehalt aber niedriger ist. Es hat sich nämlich gezeigt, daß es möglich ist, die Grenze von o,60]o des Kupfergehaltes zu unterschreiten und somit mit einem geringeren Kupfergehalt auszukommen. Es empfiehlt sich aber nicht, mit dem Kupfergehalt unter o, 5 % herunterzugehen, da dann ein erheblicher Abfall der Zugfestigkeit und der Streckgrenze reintreten würde. Die vorliegende Erfindung bezieht sich demnach auf die Verwendung eines Stahles für hochbeanspruchte Bauwerke, der bei einem Kohlenstoffgehalt von or bis o,2 % einen Kupfergehalt von über o,5 bis unter o, 6 % und einen Chromgehalt von o,25 bis o, 5 % besitzt. Durch die Herabsetzung des Kupfergehaltes ergibt sich ,ein wirtschaftlicher Vorteil, verbunden reit einer-Verbesserung der Büarbeitharkeit mit schneidendenWerkzeugen und der Schweiß;-barkeit. Außerdem wird die Gefahr von Härtungserscheinungen noch mehr herabgesetzt.The subject of the present invention is a steel whose carbon and the chromium content remains within the limits given above, its copper content but is lower. Indeed, it has been shown that it is possible to limit of o.60] o of the copper content and thus with a lower copper content get along. However, it is not recommended to go down with the copper content below 0.5%, because then there is a significant drop in tensile strength and yield strength would. The present invention therefore relates to the use of a steel for highly stressed structures, which with a carbon content of or to 0.2% a copper content of over 0.5 to below 0.6% and a chromium content of 0.25 owns up to 0.5%. The lowering of the copper content results in an economical one Advantage, combined with an improvement in workability with cutting tools and the sweat; -ability. In addition, there is still a risk of hardening more degraded.
Der Stahl kann auch geringe Mengen (bis etwa i %) von Nickel, Wolfram, Molybdän, Titan,oder Vanadin enthalten; ebenso können mit einem höheren Silicium- und Mangangehalt Vorteile verbunden werden. Unter erhöhten Mangan- und Siliciumgehalten sind solche von über o,8 bis i,3% für Mangan und von über 0,4 bis o,7% für Silicium zu verstehen.The steel can also contain small amounts (up to about i%) of nickel, tungsten, Contain molybdenum, titanium, or vanadium; with a higher silicon and manganese content benefits are linked. With increased manganese and silicon contents are those of over 0.8 to 1.3% for manganese and from over 0.4 to 0.7% for silicon to understand.
