Les sections sont produites selon la commande, la demande de prix doit donc indiquer ensemble la section, la longueur, la nuance et la norme. Les petites sections dans la plage de 3 \u00e0 12 mm se comportent comme des produits de pr\u00e9cision et sont g\u00e9n\u00e9ralement achet\u00e9es pour les instruments et les \u00e9l\u00e9ments de fixation ; la plage de 100 mm et au-del\u00e0 est achet\u00e9e comme \u00e9bauches d'usinage et tarif\u00e9e par pi\u00e8ce d\u00e9coup\u00e9e.<\/p>\n

Quel est le poids d'une barre carr\u00e9e en titane par m\u00e8tre ?<\/h2>\n

Le poids d\u00e9termine le fret et d\u00e9termine souvent si une section est exp\u00e9di\u00e9e en barre ou en \u00e9bauches d\u00e9coup\u00e9es. Calcul\u00e9 \u00e0 4,51 g\/cm3 pour Grade 2, la m\u00eame densit\u00e9 utilis\u00e9e par le calculateur de poids du titane Beiyu<\/a>; Grade 5 est environ 2 pour cent plus l\u00e9ger \u00e0 4,43 g\/cm3.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Une seule longueur de 6000 mm de 200 x 200 p\u00e8se d\u00e9j\u00e0 plus d'une tonne, c'est pourquoi les sections lourdes sont normalement command\u00e9es comme \u00e9bauches d\u00e9coup\u00e9es, avec le poids de la pi\u00e8ce convenu dans la commande plut\u00f4t qu'en barre pleine longueur.<\/p>\n

Quand la barre carr\u00e9e est-elle pr\u00e9f\u00e9rable \u00e0 la barre ronde?<\/h2>\n\n\n\n\n\n\n\n

L'argument du co\u00fbt mati\u00e8re est plus fort pour le titane que pour l'acier : chaque kilogramme usin\u00e9 a \u00e9t\u00e9 achet\u00e9 au prix du titane, adapter la section initiale \u00e0 la forme de la pi\u00e8ce s'amortit donc rapidement. La comparaison entre les quatre sections de barre figure dans choisir une section de barre en titane<\/a>.<\/p>\n

Que pr\u00e9cise la norme elle-m\u00eame quant au contenu obligatoire d'une commande ?<\/h2>\n

L'\u00e9l\u00e9ment 2 est plus important pour les barres carr\u00e9es que les acheteurs ne le pensent : ASTM B348 classe une section pleine sup\u00e9rieure \u00e0 16 pouces carr\u00e9s, 10323 millim\u00e8tres carr\u00e9s, comme billette (clause 3.1.2). Pour un carr\u00e9, cette limite se situe \u00e0 environ 102 x 102 mm, la moiti\u00e9 sup\u00e9rieure de la plage des carr\u00e9s de 3 \u00e0 500 mm est donc techniquement une billette selon la norme, offerte et certifi\u00e9e de la m\u00eame mani\u00e8re. Pour les appareils \u00e0 pression, les nuances H existent selon ASTM B348 : composition chimique identique \u00e0 celle de la nuance num\u00e9rique avec une r\u00e9sistance \u00e0 la traction minimale sp\u00e9cifi\u00e9e plus \u00e9lev\u00e9e, Grade 2H \u00e0 400 MPa (58 ksi) minimum.<\/p>\n

La gamme de sections de 3 x 3 \u00e0 500 x 500 mm et la limite de longueur de 6000 mm constituent l'enveloppe d'approvisionnement publi\u00e9e par Beiyu.

Note de p\u00e9rim\u00e8tre concernant les m\u00e9thodes d'essai : ASTM B348 cite E8 pour les essais de traction et E1409 pour l'oxyg\u00e8ne et l'azote ; ces r\u00e9f\u00e9rences d\u00e9finissent la mani\u00e8re dont les valeurs du certificat sont produites et n'ajoutent aucun contr\u00f4le au-del\u00e0 du p\u00e9rim\u00e8tre de la commande.<\/p>\n

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\\\/fr\\\/author\\\/penn-ma\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Barre carr\u00e9e en titane : dimensions, nuances et modalit\u00e9s de commande - Beiyu Titanium","robots":{"index":"index","follow":"follow","max-snippet":"max-snippet:-1","max-image-preview":"max-image-preview:large","max-video-preview":"max-video-preview:-1"},"canonical":"https:\/\/beiyutitanium.com\/fr\/titanium-square-bar-sizes-and-ordering\/","og_locale":"fr_FR","og_type":"article","og_title":"Titanium Square Bar: Sizes, Grades and How to Order - Beiyu Titanium","og_description":"Beiyu Titanium supplies square titanium bar from 3 x 3 mm up to 500 x 500 mm, in lengths up to 6000 mm, most commonly in Grade 2 and Grade 5 to ASTM B348, with an EN 10204 type 3.1 certificate by order scope.
