Diese haupts\u00e4chlich aus Nickel und Chrom bestehende, ausscheidungsgeh\u00e4rtete Legierung ist so konzipiert, dass sie extremen Umgebungen standh\u00e4lt, in denen herk\u00f6mmliche Edelst\u00e4hle versagen w\u00fcrden. F\u00fcr Beschaffungsspezialisten und Ingenieure ist das Verst\u00e4ndnis der Eigenschaften von Inconel 718 von entscheidender Bedeutung, um die strukturelle Integrit\u00e4t von Komponenten zu gew\u00e4hrleisten, die in der Luft- und Raumfahrt, der Schifffahrt sowie der \u00d6l- und Gasindustrie eingesetzt werden. Seine einzigartige Mischung aus hoher Zugfestigkeit und hervorragender Korrosionsbest\u00e4ndigkeit macht ihn zu einem Eckpfeiler der modernen Metallurgie.<\/p>\n<p data-path-to-node=\"4\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-2623\" src=\"http:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/02\/110.jpg\" alt=\"Wichtige Eigenschaften von Inconel 718: Ein technischer Leitfaden\" width=\"1200\" height=\"655\" srcset=\"https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/02\/110.jpg 1200w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/02\/110-300x164.jpg 300w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/02\/110-1024x559.jpg 1024w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/02\/110-768x419.jpg 768w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/02\/110-18x10.jpg 18w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<h3 data-path-to-node=\"5\">Verst\u00e4ndnis der Eigenschaften und der Zusammensetzung von Inconel 718<\/h3>\n<p data-path-to-node=\"6\">Die au\u00dfergew\u00f6hnliche Leistung von Inconel 718 ist eine direkte Folge seiner hochentwickelten chemischen Zusammensetzung. Im Gegensatz zu vielen anderen Superlegierungen enth\u00e4lt Inconel 718 erhebliche Mengen an Niob, das im Zusammenspiel mit Molybd\u00e4n f\u00fcr eine hohe Festigkeit sorgt, ohne dass komplexe W\u00e4rmebehandlungen erforderlich sind, die zu Rissbildung f\u00fchren k\u00f6nnten.<\/p>\n<p data-path-to-node=\"7\">The &#8220;secret sauce&#8221; of these Inconel 718 properties lies in its sluggish precipitation-hardening response. This allows the material to be welded and annealed without spontaneous hardening during heating and cooling. This characteristic is a major advantage for 28Nickel clients who require complex fabrications.<\/p>\n<table data-path-to-node=\"8\">\n<thead>\n<tr>\n<td>Element<\/td>\n<td>Inhalt (%)<\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Nickel (Ni)<\/td>\n<td>50.00 &#8211; 55.00<\/td>\n<\/tr>\n<tr>\n<td>Chrom (Cr)<\/td>\n<td>17.00 &#8211; 21.00<\/td>\n<\/tr>\n<tr>\n<td>Eisen (Fe)<\/td>\n<td>Bilanz<\/td>\n<\/tr>\n<tr>\n<td>Niobium (Nb)<\/td>\n<td>4.75 &#8211; 5.50<\/td>\n<\/tr>\n<tr>\n<td>Molybd\u00e4n (Mo)<\/td>\n<td>2.80 &#8211; 3.30<\/td>\n<\/tr>\n<tr>\n<td>Titan (Ti)<\/td>\n<td>0.65 &#8211; 1.15<\/td>\n<\/tr>\n<tr>\n<td>Aluminium (Al)<\/td>\n<td>0.20 &#8211; 0.80<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3 data-path-to-node=\"9\">Mechanische Eigenschaften von Inconel 718 bei erh\u00f6hter Temperatur<\/h3>\n<p data-path-to-node=\"10\">Eine der wichtigsten Eigenschaften von Inconel 718 ist seine F\u00e4higkeit, eine hohe mechanische Festigkeit bei Temperaturen von kryogenen Werten bis hin zu <span aria-hidden=\"true\">700\u2218C<\/span> (<span aria-hidden=\"true\">1300\u2218F<\/span>). While many metals lose their yield strength as they heat up, Inconel 718 utilizes the &#8220;gamma prime&#8221; and &#8220;gamma double prime&#8221; phases to stay rigid.<\/p>\n<ul data-path-to-node=\"11\">\n<li>\n<p data-path-to-node=\"11,0,0\">Zugfestigkeit: \u00dcbersteigt in der Regel 1375 MPa (200 ksi) nach Aush\u00e4rtung.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,1,0\">Streckgrenze: Bleibt auch unter hoher Belastung bemerkenswert stabil bei <span aria-hidden=\"true\">650\u2218C<\/span>.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,2,0\">Erm\u00fcdungsbest\u00e4ndigkeit: Die Legierung weist eine ausgezeichnete Kriechbruchfestigkeit auf und ist daher ideal f\u00fcr rotierende Teile in Turbinenmotoren.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"12\">Korrosions- und Oxidationsbest\u00e4ndigkeit<\/h3>\n<p data-path-to-node=\"13\">In rauen chemischen Umgebungen sind die Eigenschaften von Inconel 718 in Bezug auf die Korrosionsbest\u00e4ndigkeit von entscheidender Bedeutung. Der hohe Chromgehalt bildet eine sch\u00fctzende Oxidschicht, die vor Oxidation bei hohen Temperaturen sch\u00fctzt. Dar\u00fcber hinaus sorgt der Nickelgehalt daf\u00fcr, dass die Legierung resistent gegen Chlorid-Ionen-Spannungskorrosionsrisse bleibt - ein weit verbreiteter Albtraum bei Offshore-Bohrungen und in der Meerestechnik.<\/p>\n<p data-path-to-node=\"14\">Ganz gleich, ob es mit der Schwefels\u00e4ure einer Verarbeitungsanlage oder den Hochdruck-Salzen der Tiefsee konfrontiert ist, die inh\u00e4renten Eigenschaften von Inconel 718 gew\u00e4hrleisten Langlebigkeit und reduzierte Wartungskosten f\u00fcr industrielle Betreiber.<\/p>\n<h3 data-path-to-node=\"15\">Herstellung und Verarbeitbarkeit<\/h3>\n<p data-path-to-node=\"16\">Despite being a &#8220;super&#8221; alloy, Inconel 718 is surprisingly workable. Most users appreciate that these Inconel 718 properties include excellent weldability. It is resistant to post-weld age cracking, which is a frequent issue with other nickel-based superalloys like Inconel 713 or Ren\u00e9 41. At 28Nickel, we often advise our clients that while the material is tough, using the right carbide tooling and coolant can lead to highly efficient machining processes.<\/p>\n<h3 data-path-to-node=\"17\">Anwendungen, die von den Eigenschaften von Inconel 718 bestimmt werden<\/h3>\n<p data-path-to-node=\"18\">Wo sehen wir diese Eigenschaften von Inconel 718 in Aktion?<\/p>\n<ol start=\"1\" data-path-to-node=\"19\">\n<li>\n<p data-path-to-node=\"19,0,0\">Luft- und Raumfahrt: Triebwerkskomponenten, einschlie\u00dflich Schaufeln, Geh\u00e4use und Auspuffrohre.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"19,1,0\">\u00d6l und Gas: Hochfeste Verschraubungen, Komponenten f\u00fcr Bohrlochwerkzeuge und Bohrlochkopfteile.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"19,2,0\">Kernenergie: Brennelement-Abstandshalter und Spezialfedern.<\/p>\n<\/li>\n<\/ol>\n<p data-path-to-node=\"20\">Die Vielseitigkeit dieser Legierung ergibt sich direkt aus der Tatsache, dass die Eigenschaften von Inconel 718 keine Kompromisse eingehen; Sie erhalten Festigkeit, Duktilit\u00e4t und Korrosionsbest\u00e4ndigkeit in einem einzigen Paket.<\/p>\n<hr data-path-to-node=\"21\" \/>\n<h3 data-path-to-node=\"22\">Verwandte Fragen und Antworten<\/h3>\n<p data-path-to-node=\"23\">Q1: Was ist die maximale Betriebstemperatur f\u00fcr Inconel 718?<\/p>\n<p data-path-to-node=\"23\">Die mechanischen Eigenschaften von Inconel 718 bleiben bis zu etwa <span aria-hidden=\"true\">700\u2218C<\/span> (<span aria-hidden=\"true\">1300\u2218F<\/span>).
