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 <5- 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) 195g 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 remainder consists of iron, 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 one stainless steel that does not contain any free <5 ferrite and a slight structural hardening with good Reproducibility of its mechanical properties allowed. About the toughness and strength properties This patent does not contain any of this known steel and special fields of application Declarations. From Küntscher-Kilger-Biegler »Technical Structural Steel«, 3rd edition, Halle (Saale) 195g Pages 374/375 and 404, it is also known that niobium can be added to stainless steels. From it however, they are also not specific information with regard to toughness and strength properties as well as special fields of application of the steels described therein.
In der Patentanmeldung P 14 58 330 ist die Verwendung einer zähen, aushärtungshärtbaren, rostfreien, chrom-, nickel- 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-In the patent application P 14 58 330 is the use of a tough, age hardenable, rustproof, chromium, nickel and aluminum-containing steel alloy made 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 direction at room temperature in the hardened state
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.and transverse direction, an elongation within 50.8 mm gauge length of at least 8% and a constriction of at least 29.3%, such as compound machined, welded or soldered Parts of pressure vessels or missiles described.
Die in der vorliegenden Zusatzanmeldung beschriebene Erfindung stellt nun eine weitere Ausgestaltung des Gegenstandes der oben genannten Hauptpatentanmeldung dar und betrifft die Verwendung einer zähen, ausscheidungshärtbaren, rostfreien, chrom-, nickel- und aluminiumhaltigen Stahllegierung der vorstehend angegebenen Zusammensetzung für den in dem Hauptpatent genannten Zweck, die zusätzlich noch mehr als 0,10 und bis zu 0,50% Titan und/oder bis zu 0,75% Niob enthält. Beste Ergebnisse werden erzielt, wenn die Stahllegierung der vorstehend angegebenen Zusammensetzung 0,10 bis 0,50% Niob und weniger als 0,015% Schwefel enthält.The invention described in the present additional application represents a further embodiment the subject of the above-mentioned main patent application and relates to the use of a tough, precipitation hardenable stainless, chromium, nickel and aluminum containing steel alloys of the above Composition for the purpose mentioned in the main patent, which are additionally more than 0.10 and contains up to 0.50% titanium and / or up to 0.75% niobium. Best results are obtained when the steel alloy of the composition given above, 0.10 to 0.50% niobium and less than 0.015% sulfur contains.
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 intergranular or intergranular corrosion in the freshly welded as well as in the welded state and precipitation hardened state, and they are in the hardened state after welding or brazing particularly 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 production of parts, in which 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 one The atmosphere.
