The chemistry brackets and testing rules in the DIN documents differ in detail from their ASTM counterparts, so the drawing&#8217;s own standard always governs. When we quote against a Werkstoffnummer drawing, the reconciliation happens on the mill test certificate, where the reported chemistry and mechanical values can be checked against both documents before material is released.<\/p>\n<p>Um einen Grade direkt \u00fcber Nummer, UNS, Werkstoffnummer oder Norm nachzuschlagen, nutzen Sie das <a href=\"https:\/\/beiyutitanium.com\/de\/titanium-standards-astm-en-din-cross-reference\/\">Titan-Grade-Vergleichswerkzeug<\/a>. Der Rest dieser Seite behandelt, was eine deutsche Zeichnung konkret verlangt und wie ASTM-Halbzeug dagegen bestellt wird.<\/p>\n<h2>Wie spezifizieren deutsche Zeichnungen Titan?<\/h2>\n<p>Eine deutsche Titan-Spezifikation besteht \u00fcblicherweise aus drei Teilen: der Werkstoffnummer f\u00fcr den Werkstoff selbst, einer DIN-Produktnorm f\u00fcr die Erzeugnisform und einer Zeugnisanforderung. Die Zusammensetzung steht in DIN 17850 f\u00fcr unlegiertes Titan und DIN 17851 f\u00fcr Titanlegierungen. Die Produktnormen sind DIN 17860 f\u00fcr Bleche und B\u00e4nder, DIN 17862 f\u00fcr Stangen und DIN 17864 f\u00fcr Schmiedest\u00fccke. \u00c4ltere Zeichnungen nennen mitunter auch DIN 17861 f\u00fcr nahtlose Rohre; das Dokument ist zur\u00fcckgezogen, entsprechende Verweise sind aber weiter im Umlauf und werden gel\u00f6st, indem die aktuell g\u00fcltige Norm vereinbart wird, nach der das Rohr tats\u00e4chlich gefertigt wird. Die Zeugniszeile lautet \u00fcblicherweise EN 10204 3.1, Nachfolger des alten DIN 50049 3.1B, und genau diesen Zeugnistyp stellt <a href=\"https:\/\/beiyutitanium.com\/de\/astm-b348-titanium-bar-billet-guide\/\">Beiyu Titanium mit ASTM-B348-Stangen<\/a>, <a href=\"https:\/\/beiyutitanium.com\/de\/astm-b265-titanium-sheet-plate-guide\/\">ASTM-B265-Blechen und -Platten<\/a> und <a href=\"https:\/\/beiyutitanium.com\/de\/astm-b381-titanium-forgings-guide\/\">ASTM-B381-Schmiedest\u00fccken<\/a> standardm\u00e4\u00dfig aus.<\/p>\n<h2>Worin unterscheiden sich 3.7164 und 3.7165?<\/h2>\n<p>Beide Nummern bezeichnen Ti-6Al-4V, und die ver\u00f6ffentlichten Analysentabellen stimmen weitgehend \u00fcberein. Der praktische Unterschied liegt darin, wo die jeweilige Nummer zu Hause ist: 3.7164 ist die Nummer der Luftfahrtunterlagen und bringt Spezifikations- und Pr\u00fcfumfang auf Luftfahrtniveau mit, w\u00e4hrend 3.7165 die Industrievariante ist, die dem ASTM Grade 5 entspricht, wie er als B348-Stange oder B265-Flachzeug geliefert wird. Zeigt eine Zeichnung 3.7164 zusammen mit einer Luftfahrtspezifikation, ist als Luftfahrtauftrag anzubieten, nicht als kommerzieller Grade-5-Ersatz. Zeigt sie 3.7165 mit einer DIN-Produktnorm, erwartet der K\u00e4ufer \u00fcblicherweise kommerzielles Grade-5-Halbzeug mit 3.1-Zeugnis, vor Angebotsabgabe gegen die Zeichnung best\u00e4tigt.<\/p>\n<h2>Welche Nummer gilt f\u00fcr Grade 23, die ELI-Variante?<\/h2>\n<p>Fuer Ti-6Al-4V ELI ist keine eigene Werkstoffnummer gebr\u00e4uchlich. Deutsche Zeichnungen schreiben \u00fcblicherweise 3.7165 ELI oder nennen direkt die ASTM-Norm. Zu beachten: Die UNS-Nummer h\u00e4ngt dann davon ab, nach welcher Norm bestellt wird. ASTM B348 (Stangen), B265 (Bleche) und B863 (Draht) f\u00fchren Grade 23 als UNS R56407, die Implantatnorm ASTM F136 dagegen als UNS R56401. Der Unterschied, und wann sich welche Variante lohnt, steht in unserem <a href=\"https:\/\/beiyutitanium.com\/de\/grade-5-vs-grade-23-titanium\/\">Vergleich Grade 5 zu Grade 23<\/a>.<\/p>\n<h2>ASTM-Halbzeug gegen eine Zeichnung mit Werkstoffnummer bestellen<\/h2>\n<p>Die meiste Titan-Halbzeugproduktion au\u00dferhalb Europas l\u00e4uft nach ASTM-Spezifikationen. K\u00e4ufer mit einer DIN-Zeichnung bestellen deshalb \u00fcblicherweise den entsprechenden ASTM-Grade und weisen die DIN-Anforderung \u00fcber das Zeugnis nach. Damit das reibungslos funktioniert, sollte eine Anfrage enthalten: die Werkstoffnummer und die DIN-Norm exakt wie auf der Zeichnung, den ersatzweise zu akzeptierenden ASTM-Grade, Form und Abmessungen mit Toleranz, Zustand und Oberfl\u00e4che sowie die Zeugnisanforderung, \u00fcblicherweise EN 10204 3.1 mit Schmelzenr\u00fcckverfolgbarkeit. Wir legen die beiden Analysenfenster im Angebotsstadium nebeneinander und markieren jeden Punkt, an dem die DIN-Grenze enger ist als die ASTM-Grenze, damit der Ersatz vor Produktionsfreigabe vereinbart ist und nicht erst im Wareneingang diskutiert wird.
