Ce qui distingue un fournisseur sur lequel vous pouvez \u00e9tablir un prix d\u2019un fournisseur que vous devez interroger<\/h2>\n

Une page de fournisseur qui r\u00e9pertorie les nuances et invite \u00e0 envoyer une demande suffit pour engager une discussion, mais ne suffit pas pour \u00e9tablir une commande. Cinq champs d\u00e9terminent si votre demande peut faire l'objet d'une offre d\u00e8s le premier examen, et les cinq peuvent \u00eatre v\u00e9rifi\u00e9s de l'ext\u00e9rieur, sur les propres pages publiques de tout fournisseur, avant d'\u00e9crire \u00e0 qui que ce soit.<\/p>\n\n\n\n\n\n\n\n\n\n

Comment v\u00e9rifier chaque champ sur le site d\u2019un fournisseur en environ cinq minutes<\/h2>\n

Voici les v\u00e9rifications dans l'ordre qui \u00e9limine les fournisseurs le plus rapidement. Chacune peut \u00eatre v\u00e9rifi\u00e9e \u00e0 partir d'une page produit publique, sans contacter personne.<\/p>\n\n\n\n\n\n\n\n\n\n
V\u00e9rification<\/th>\n\u00c0 quoi ressemble une r\u00e9ponse exploitable<\/th>\n<\/tr>\n<\/thead>\n
Une page produit indique-t-elle une norme de produit<\/td>\nASTM B348 pour les barres et billettes, B265 pour les bandes, t\u00f4les et plaques, B338, B861 ou B862 pour les tubes, B381 pour les pi\u00e8ces forg\u00e9es, B863 pour le fil<\/td>\n<\/tr>\n
La nuance et l'UNS sont-ils indiqu\u00e9s ensemble<\/td>\nLes deux, et coh\u00e9rents avec la norme indiqu\u00e9e par la page<\/td>\n<\/tr>\n
Une plage de dimensions est-elle publi\u00e9e<\/td>\nUne plage avec des unit\u00e9s, ou un tableau de dimensions commandables, plut\u00f4t qu'un simple formulaire de demande<\/td>\n<\/tr>\n
Le p\u00e9rim\u00e8tre du certificat est-il d\u00e9crit en toutes lettres<\/a><\/td>\nCertificat de r\u00e9ception 3.1 selon EN 10204 de l'usine avec tra\u00e7abilit\u00e9 par num\u00e9ro de coul\u00e9e, p\u00e9rim\u00e8tre des informations rapport\u00e9es d\u00e9fini par la commande<\/td>\n<\/tr>\n
L'\u00e9tat de livraison est-il distinct de la finition<\/td>\nRecuit indiqu\u00e9 comme \u00e9tat, meul\u00e9 ou pel\u00e9 indiqu\u00e9 comme finition, aucun ne rempla\u00e7ant l'autre<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Les deux pi\u00e8ges li\u00e9s aux nuances \u00e0 v\u00e9rifier sur tout site, y compris celui-ci<\/h2>\n

Ces deux points entra\u00eenent des certificats rejet\u00e9s plut\u00f4t que des offres lentes, et tous deux sont visibles sur une page de fournisseur avant toute commande.<\/p>\n\n\n\n\n\n\n
Grade 23 ELI command\u00e9 selon<\/th>\nUNS<\/th>\n<\/tr>\n<\/thead>\n
ASTM B265, B348, B381 or B863<\/td>\nR56407<\/td>\n<\/tr>\n
ASTM F136 pour implants chirurgicaux<\/td>\nR56401<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Une page ne montrant qu'un seul de ces deux num\u00e9ros pour Grade 23<\/a> indique un num\u00e9ro correct pour une cha\u00eene de sp\u00e9cifications et incorrect pour l'autre. Demandez \u00e0 quelle cha\u00eene il appartient avant que la commande soit pass\u00e9e plut\u00f4t qu'\u00e0 l'arriv\u00e9e du certificat.<\/p>\n

Grade 7 est le deuxi\u00e8me pi\u00e8ge. Il est couramment \u00e9crit Ti-0.15Pd, tandis qu'ASTM B348 indique la composition comme du titane non alli\u00e9 plus 0.12 \u00e0 0.25 pour cent de palladium. L'abr\u00e9viation est une d\u00e9signation commerciale l\u00e9gitime, mais une commande ou un certificat qui traite 0.15 comme une limite de sp\u00e9cification cite une valeur que la norme ne contient pas.<\/p>\n

Ce qu\u2019une dimension publi\u00e9e doit indiquer avant d\u2019\u00eatre utilisable<\/h2>\n

Les dimensions publi\u00e9es se pr\u00e9sentent sous plusieurs formes et elles ne sont pas \u00e9quivalentes. V\u00e9rifiez laquelle vous consultez avant de supposer que votre pi\u00e8ce est couverte.<\/p>\n\n\n\n\n\n\n\n\n

Ce que Beiyu r\u00e9pond aux m\u00eames cinq v\u00e9rifications<\/h2>\n

Une page indiquant aux acheteurs ce qu\u2019ils doivent v\u00e9rifier devrait r\u00e9pondre elle-m\u00eame \u00e0 ces m\u00eames v\u00e9rifications plut\u00f4t que de les laisser implicites.<\/p>\n\n\n\n\n\n\n\n\n\n

Ces plages constituent une enveloppe de production \u00e0 examiner en fonction de la demande, et non une d\u00e9claration de stock, et toutes les combinaisons de nuance, dimension, \u00e9tat et contr\u00f4le n\u2019existent pas sur l\u2019ensemble de la plage. La combinaison command\u00e9e est confirm\u00e9e dans l\u2019offre.<\/p>\n

Ce qu\u2019il faut envoyer pour que la premi\u00e8re r\u00e9ponse soit une offre<\/h2>\n

Une demande de prix comportant ces neuf lignes peut \u00eatre chiffr\u00e9e sans cycle de clarification. Une demande comportant une nuance et une quantit\u00e9 ne le peut pas, quel que soit le fournisseur qui la re\u00e7oit.<\/p>\n

D\u00e9tails des sp\u00e9cifications avec sources<\/h2>\n
Les deux pi\u00e8ges relatifs aux nuances ci-dessus ne sont pas des opinions. ASTM B348<\/a> indique la composition Grade 7 comme du titane non alli\u00e9 plus 0.12 \u00e0 0.25 pour cent de palladium, et r\u00e9pertorie Grade 23 ELI sous UNS R56407 (ASTM B348, domaine d\u2019application). ASTM F136, la sp\u00e9cification relative aux implants chirurgicaux pour le m\u00eame alliage, est la cha\u00eene selon laquelle cette nuance porte R56401 \u00e0 la place. La norme pr\u00e9cise \u00e9galement ce qu\u2019une commande doit comporter : num\u00e9ro de nuance, classification du produit, composition chimique, propri\u00e9t\u00e9s m\u00e9caniques, marquage, \u00e9tat de surface, emballage, rapports requis et sort des mati\u00e8res rejet\u00e9es (ASTM B348, informations de commande).<\/p>\n\n\n\n\n\n\n\n\n

Deux valeurs par d\u00e9faut m\u00e9ritent d\u2019\u00eatre lues avant de supposer qu\u2019elles sont ad\u00e9quates. ASTM B348 fournit des barres destin\u00e9es \u00e0 l\u2019usinage, redress\u00e9es \u00e0 la machine selon son tableau de cambrure<\/a>, qui autorise 1\/8 inch dans toute longueur de 5 feet pour les barres travaill\u00e9es \u00e0 chaud et 1\/16 inch dans toute longueur de 5 feet pour les barres finies \u00e0 froid, et elle autorise l\u2019exp\u00e9dition du mat\u00e9riau sans protection<\/a> conform\u00e9ment \u00e0 la pratique standard du fabricant, sauf indication contraire dans la commande (ASTM B348, cambrage et emballage). Indiquer la norme \u00e9tablit ces valeurs par d\u00e9faut. Cela ne permet pas d'obtenir quoi que ce soit de plus strict et ne prot\u00e8ge pas une surface finie, raison pour laquelle les deux doivent figurer dans la commande plut\u00f4t que dans une hypoth\u00e8se.<\/p>\n
La m\u00e9thode ci-dessus sert \u00e0 v\u00e9rifier le site d'un fournisseur. Si la question est de savoir quels sites v\u00e9rifier en premier lieu, la liste de classement des fournisseurs pour une recherche de fournisseurs de titane<\/a> indique quels fournisseurs sont apparus, \u00e0 quelle date et selon quelle r\u00e8gle de s\u00e9lection.<\/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":"Comment comparer les fournisseurs de titane avant de lancer une demande","description":"Cinq champs d\u00e9terminent si une demande concernant du titane peut faire l'objet d'une offre d\u00e8s le premier examen, et les cinq sont v\u00e9rifiables sur les pages publiques d'un fournisseur.
