Description

Die Erfindung betrifft die Verwendung einer zähen, ausscheidungshärtbaren, rostfreien, chrom-, nickel- und aluminiumhaltigen Stahllegierung als Werkstoff für bestimmte Gegenstände, wie zusammengesetzte maschinenverarbeitete, geschweißte oder gelötete Teile von Druckkesseln oder Flugkörpern.The invention relates to the use of a tough, precipitation hardenable, stainless, chrome, nickel and aluminum-containing steel alloy as a material for certain items, such as composite machine-processed, welded or soldered parts of pressure vessels or missiles.

In der US-Patentschrift 31 31 055 ist eine Stahllegierung beschrieben, die aus 5 bis 16,5% Chrom, 10 bis 18,5% Nickel, 1 bis 6% Aluminium, bis zu 0,15% Kohlenstoff, bis zu 4% Mangan, bis zu 2% Silicium und zum Rest aus Eisen besteht, wobei das Aluminium teilweise durch Titan und/oder Molybdän ersetzt sein kann und der Aluminiumgehalt nicht unter 0,5% fällt. Dabei handelt es sich um einen ausscheidungshärtbaren rostfreien Stahl, der keinen freien cf-Ferrit enthält und eine leichte Strukturhärtung unter Erzielung einer guten Reproduzierbarkeit seiner mechanischen Eigenschaften erlaubt. Über die Zähigkeits- und Festigkeitseigenschaften dieses bekannten Stahls und über spezielle Anwendungsgebiete enthält diese Patentschrift keinerlei Angaben. Aus Küntscher-Kilger-Biegler, »Technische Baustähle«, 3. Auflage, Halle (Saale) 1958, Seiten 374/375 und 404, ist es ferner bekannt, daß rostfreien Stählen Niob zugesetzt werden kann. Daraus sind jedoch ebenfalls keine spezifischen Angaben in bezug auf Zähigkeits- und Festigkeitseigenschaften sowie spezielle Anwendungsgebiete der darin beschriebenen Stähle zu entnehmen.In US Pat. No. 31 31 055, a steel alloy is described, which consists of 5 to 16.5% chromium, 10 to 18.5% nickel, 1 to 6% aluminum, up to 0.15% carbon, up to 4% manganese, up to 2% silicon and the The remainder consists of iron, with the aluminum being partially replaced by titanium and / or molybdenum and the aluminum content does not fall below 0.5%. It is a precipitation hardenable stainless steel Steel that does not contain free cf ferrite and is a light one Structural hardening is allowed while achieving good reproducibility of its mechanical properties. About the toughness and strength properties of this well-known steel and about special areas of application this patent specification does not contain any information. From Küntscher-Kilger-Biegler, »Technical Structural Steel«, 3rd edition, Halle (Saale) 1958, pages 374/375 and 404 is it is also known that niobium can be added to stainless steels. However, none of these are either specific information regarding toughness and strength properties as well as special areas of application of the steels described therein.

In dem Patent 14 58 330 ist die Verwendung einer zähen, ausscheidungshärtbaren, rostfreien, chrom-, nikkel- und aluminiumhaltigen Stahllegierung, die aus 11,5 bis 13,5% Chrom, 7,0 bis 10,0% Nickel, 0,5 bis 1,5% Aluminium, 1,75 bis 2,50% Molybdän, bis zu 0,05% Kohlenstoff, bis zu 0,50% Mangan, bis zu 0,60% Silicium, bis zu 0,020% Schwefel, bis zu 0,05% Stickstoff, Rest Eisen einschließlich erschmelzungsbedingter Verunreinigungen besteht, als Werkstoff für Gegenstände, die bei Raumtemperatur in ausgehärtetem Zustand eine Mindestzugfestigkeit von 149,0 kg/mm2 in der Längs- und Querrichtung, eine Dehnung innerhalb 50,8 mm Meßlänge von mindestens 8% und eine Einschnürung von mindestens 29,3% aufweisen, wie zusammengesetzte maschinenverarbeitete, geschweißte oder gelötete Teile von Druckkesseln oder Flugkörpern, beschrieben.In the patent 14 58 330 is the use of a tough, precipitation hardenable, stainless, chromium, nickel and aluminum-containing steel alloy consisting of 11.5 to 13.5% chromium, 7.0 to 10.0% nickel, 0.5 up to 1.5% aluminum, 1.75 to 2.50% molybdenum, up to 0.05% carbon, up to 0.50% manganese, up to 0.60% silicon, up to 0.020% sulfur, up to 0 .05% nitrogen, the remainder iron, including impurities caused by the melting, as a material for objects that have a minimum tensile strength of 149.0 kg / mm 2 in the longitudinal and transverse direction at room temperature in the hardened state, an elongation within 50.8 mm measuring length of at least 8% and a necking of at least 29.3%, as described as assembled, machine-processed, welded or soldered parts of pressure vessels or missiles.

Die hier beschriebene Erfindung stellt nun eine weitere Ausgestaltung des Gegenstandes des oben genannten Patents dar und betrifft die Verwendung einer zähen, ausscheidungshärtbaren, rostfreien, chrom-, nickel- und aluminiumhaltigen Stahllegierung der vorstehend angegebenen Zusammensetzung für den in dem Patent genannten Zweck, die zusätzlich noch mehr als 0,10 und bis zu 0,50% Titan und/oder bis zu 0,75% Niob enthält.The invention described here represents a further embodiment of the subject matter of the above Patent and relates to the use of a tough, precipitation hardenable, rustproof, chrome, nickel and aluminous steel alloy of the above composition for the one in the patent mentioned purpose, which also contains more than 0.10 and up to 0.50% titanium and / or up to 0.75% niobium.

Beste Ergebnisse werden erzielt, wenn die Stahllegierung der vorstehend angegebenen Zusammensetzung 0,10 bis 0,50% Niob und weniger als 0,015% Schwefel enthält.Best results are obtained when the steel alloy has the composition given above Contains 0.10 to 0.50% niobium and less than 0.015% sulfur.

Die erfindungsgemäß verwendeten titanhaltigen und/ oder niobhaltigen Stähle sind frei von jeder interkristallinen oder intergranulären Korrosion im frisch geschweißten Zustand sowie im geschweißten und ausscheidungsgehärteten Zustand und sie sind im gehärteten Zustand nach dem Schweißen oder Hartlöten besonders korrosionsbeständig.The titanium-containing and / or niobium-containing steels used according to the invention are free of any intergranularity or intergranular corrosion in the freshly welded state as well as in the welded and precipitation hardened Condition and they are special in the hardened condition after welding or brazing corrosion resistant.

Die erfindungsgemäß verwendete Stahllegierung eignet sich insbesondere für die Herstellung von Teilen, bei denen Spannungen längs aller drei Hauptachsen auftreten. Der erfindungsgemäß zu verwendende Stahl weist eine ausgezeichnete Spannungsrißkorrosionsbeständigkeit auf selbst in einer stark salzhaltigen Atmosphäre.The steel alloy used according to the invention is particularly suitable for the manufacture of parts where stresses occur along all three main axes. The steel to be used according to the invention has excellent stress corrosion cracking resistance even in a highly saline atmosphere.
