Description

Korrosions- und feuerbeständige Chromstahllegierung Für Gegenstände, die gegen Einwirkung einer hohen Hitze beständig sein sollen, hat man noch keine vollkommen geeignete Stahllegierung gefunden. Es gibt Stahllegierungen mit hohem Chrom- und Nickelgehalt, die gegen die Einwirkung hoher Hitze beständig sind; die Gestehungskosten dieser Stahllegierungen sind aber derart hohe, daB sie deren Verwendungsmöglichkeit für viele Zwecke ausschließen.Corrosion and fire resistant chrome steel alloy For items, which are supposed to be resistant to the action of high heat are not yet available completely suitable steel alloy found. There are steel alloys with high Chromium and nickel content resistant to exposure to high heat; the The production costs of these steel alloys are so high that they can be used exclude for many purposes.

Gemäß der vorliegenden Erfindung ist es nun gelungen, durch einen Zusatz von Tantal zu einem Chromstähl bekannter Zusammensetzung eine Stahllegierung herzustellen, die eine außerordentlich hohe Beständigkeit gegen Hitzeeinwirkung zeigt, verbunden mit Säurebeständigkeit.According to the present invention it has now been achieved by a Addition of tantalum to a chromium steel of known composition, a steel alloy produce that have an extremely high resistance to heat shows associated with acid resistance.

Versuche haben ergeben, daß ein Stahl von 0,2 % C, 1 °/o Si, i9 % Cr und 8 °% Ta, der durch 5o Stunden einer Temperatur von I IOo bis 1 3o0° C ausgesetzt wurde, keine Spuren der Einwirkung dieser Wärmebehandlung aufwies. Für besondere Fälle hat sich auch ein Mo-Zusatz von 0,5 bis 3,5 °% vorteilhaft erwiesen.Tests have shown that a steel of 0.2% C, 1 ° / o Si, i9% Cr and 8 °% Ta which has been exposed by 5o hours a temperature of from ioo I 3o0 to 1 ° C, no traces of the action of this heat treatment exhibited. An addition of 0.5 to 3.5% Mo has also proven advantageous for special cases.
