EMI1.1
Für Gegenstände, die gegen Einwirkungen hoher Hitze beständig sein sollen, hat man noch keine vollkommen geeignete Stahllegierung gefunden. Die bisher bekannten Chromstahllegierungen, selbst mit hohen Chrom-und Nickelgehalten, die bekannterweise gegen Hitze-und Korrosionseinwirkungen widerstandsfähig sind, können den Anforderungen hoher Temperaturen und bestimmter Korrosionseinflüsse nur genügen, wenn Chrom und Nickel in Mengen angewendet werden, die ihr Verwendunggebiet infolge der Kostspieligkeit ihrer Komponenten einschränken.
Aus dieser Erkenntnis heraus wird bei der vorliegenden Erfindung durch Einführung eines neuen Elementes, des Tantals, im Ausmasse von l bis 20% eine Widerstandsfähigkeit gegen hohe Temperaturen und Korrosion der bekannten Stähle in ausserordentlich hohem Masse erreicht. Es sind zwar Legierungen mit Tantalzusatz bekannt, diese Legierungen fanden aber bisher nur als Werkzeug-und Konstruktionsstähle für besonders hohe Beanspruchungen Verwendung, während der günstige Einfluss des Tantals auf die Hitze-und Korrosionsbeständigkeit bisher nicht erkannt wurde.

und ein Siliziumzusatz von 1 bis 5% als vorteilhaft erwiesen.

EMI1.1
A completely suitable steel alloy has not yet been found for objects that are supposed to be resistant to the effects of high heat. The previously known chromium steel alloys, even with high chromium and nickel contents, which are known to be resistant to the effects of heat and corrosion, can only meet the requirements of high temperatures and certain corrosion effects if chromium and nickel are used in amounts that suit their area of use due to the cost of their Restrict components.
On the basis of this knowledge, the present invention achieves an extraordinarily high resistance to high temperatures and corrosion of the known steels by introducing a new element, tantalum, in the range of 1 to 20%. Alloys with added tantalum are known, but so far these alloys have only been used as tool and structural steels for particularly high loads, while the beneficial influence of tantalum on the heat and corrosion resistance has not yet been recognized.
EMI1.2
and a silicon addition of 1 to 5% has proven advantageous.
