Over 15 years in titanium export he has learned to review each specification line himself, checking grade, standard, dimensions, tolerance and certificate scope against mill capability before quoting, rather than routing enquiries through a sales desk. He came to titanium supply from the other side of the transaction. Before leading Beiyu's international business he worked at Koch (Koch-Glitsch) and was directly involved in delivering a SABIC petrochemical project in Fujian, China. That work was built on inspection and test plans, material certification and heat traceability, third party inspection coordination, and project documentation and dossier control. Those are the same four things a process industry or regulated buyer will hold a titanium supplier to, and having had to enforce them as a customer is why they are treated here as part of the supply rather than as paperwork produced afterwards. His day-to-day work spans the questions this site is written to answer: choosing between commercially pure and alloyed titanium grades for a corrosive service, reading a mill test certificate against the ordered standard, and matching a buyer's designation (ASTM grade, UNS, German Werkstoff number or French NF code) to the same metal across markets. Beiyu supplies titanium, nickel-alloy and refractory mill products across bar, rod, plate, tube, block, ring, coil, ingot, forgings and machined parts, with EN 10204 3.1 documentation and heat-number traceability.\",\"url\":\"https:\\\/\\\/beiyutitanium.com\\\/de\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Gesch\u00e4lter, gedrehter oder geschliffener Titanstab: Welche Variante bestellen","description":"Jeder Oberfl\u00e4chenzustand bringt eine eigene, bereits eingebaute Durchmessertoleranz, Oberfl\u00e4che und Bearbeitungszugabe mit.

In \u00fcber 15 Jahren Titanexport hat er gelernt, jede Spezifikationszeile selbst zu pr\u00fcfen und Grade, Norm, Abmessungen, Toleranz und Zertifikatsumfang gegen die Werkskapazit\u00e4t abzugleichen, bevor er anbietet, statt Anfragen \u00fcber eine Vertriebsstelle zu leiten. Zur Titanlieferung kam er von der anderen Seite des Gesch\u00e4fts. Bevor er das internationale Gesch\u00e4ft von Beiyu leitete, arbeitete er bei Koch (Koch-Glitsch) und war direkt an der Abwicklung eines petrochemischen SABIC-Projekts in Fujian, China, beteiligt. Diese Arbeit beruhte auf Pr\u00fcf- und Inspektionspl\u00e4nen, Werkstoffzertifizierung und Chargen-R\u00fcckverfolgbarkeit, der Koordination von Fremdabnahmen sowie Projektdokumentation und Dossierkontrolle. Das sind dieselben vier Dinge, an denen ein K\u00e4ufer aus der Prozessindustrie oder ein regulierter K\u00e4ufer einen Titanlieferanten misst, und weil er sie selbst als Kunde durchsetzen musste, werden sie hier als Teil der Lieferung behandelt, nicht als nachtr\u00e4glich erstellte Unterlagen. Seine t\u00e4gliche Arbeit umfasst die Fragen, die diese Website beantworten soll: die Wahl zwischen Reintitan und legierten Titan-Grades f\u00fcr einen korrosiven Einsatz, das Lesen eines Werkstoffzeugnisses gegen die bestellte Norm und das Zuordnen einer K\u00e4uferbezeichnung (ASTM-Grade, UNS, deutsche Werkstoffnummer oder franz\u00f6sischer NF-Code) zu demselben Metall \u00fcber verschiedene M\u00e4rkte hinweg. Beiyu liefert Halbzeuge aus Titan, Nickellegierungen und Refrakt\u00e4rmetallen in Stab, Rundstab, Platte, Rohr, Block, Ring, Coil, Barren, Schmiedeteilen und zerspanten Teilen, mit Dokumentation nach EN 10204 3.1 und Chargennummer-R\u00fcckverfolgbarkeit.","url":"https:\/\/beiyutitanium.com\/de\/author\/penn-ma\/"}]}},"_links":{"self":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/5428","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/comments?post=5428"}],"version-history":[{"count":2,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/5428\/revisions"}],"predecessor-version":[{"id":5492,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/5428\/revisions\/5492"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/media\/5257"}],"wp:attachment":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/media?parent=5428"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/categories?post=5428"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/tags?post=5428"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
