{"id":119,"count":4,"description":"L'acquisto di Nickel 200 e Nickel 201 inizia dall'UNS esatto e dalla forma del prodotto. Questa categoria indirizza le richieste di offerta industriali verso Tubo senza saldatura in Nickel 200 \/ 201<\/a>, tubo senza saldatura Nickel 200<\/a>, barre Nickel 200<\/a>, e lamiera spessa Nickel 201<\/a>. ASTM B160 si applica a tondi e barre, ASTM B161 a tubi senza saldatura e ASTM B162 a lamiere spesse, lamiere sottili e nastro quando viene ordinata la norma applicabile.\nNickel 201 ha un limite di carbonio inferiore a Nickel 200, ma la scelta del grado deve seguire la specifica tecnica dell'acquirente e la valutazione dell'impiego. Inviare UNS esatto, norma di prodotto, dimensioni, stato, quantit\u00e0, dati di esercizio e documenti di controllo richiesti. MTC, EN 10204 3.1, tracciabilit\u00e0 della colata o del lotto e controllo non distruttivo sono inclusi solo quando concordati nell'offerta e nell'ordine d'acquisto.\n\n

Dettagli delle specifiche con fonti<\/h2>\n

I limiti di composizione chimica ASTM sono ci\u00f2 che distingue effettivamente i due gradi di nichel puro: Nickel 200 ammette carbonio fino a 0,15 per cento, mentre Nickel 201 lo limita a 0,02 per cento, ed entrambi richiedono almeno 99,0 per cento di nichel. Questo limite del carbonio spiega perch\u00e9 ASM Handbook e i dati dei produttori collocano il servizio continuo di Nickel 200 a non oltre 315 C, affidando a Nickel 201 il servizio a temperature superiori, dove il grado a maggiore contenuto di carbonio diventerebbe fragile per grafitizzazione.<\/p>\n

Beiyu formula offerte per tubi Nickel 200 e Nickel 201 secondo ASTM B163 nell'ambito della propria gamma di fornitura documentata: tubi capillari con diametro esterno da 1 a 5 mm e spessore di parete da 0.1 a 2 mm in lunghezze fino a 6000 mm, tubi senza saldatura con diametro esterno da 5 a 325 mm e spessore di parete da 0.5 a 12 mm e tubi saldati con diametro esterno da 6.35 a 1219 mm, entrambi in lunghezze fino a 12000 mm, affiancati da filo di nichel puro da 0.5 a 6.0 mm. Prima dell'offerta Beiyu esamina sei campi di ogni richiesta di offerta per nichel puro, grado, norma, dimensioni, tolleranza, stato superficiale e ambito del controllo; il rilascio prevede l'analisi chimica tramite uno di due percorsi di laboratorio, seguita dal controllo dimensionale e dal collaudo di terza parte quando concordato nell'ordine.<\/p>\n

Gamma di fornitura del nichel commercialmente puro<\/h2>\n

Nickel 200 e Nickel 201 si distinguono per il contenuto di carbonio, quindi la richiesta deve indicare il numero anzich\u00e9 descrivere il metallo. Una volta fissato il grado, la forma determina la gamma.<\/p>\n\n\n

Nickel 201 \u00e8 la versione a basso tenore di carbonio, specificata per un servizio prolungato ad alta temperatura, dove il carbonio contenuto in Nickel 200 causa infragilimento. La barra viene quotata secondo ASME SB-160 e ASTM B160, la lamiera spessa secondo ASME SB-162 e ASTM B162 e il tubo senza saldatura secondo ASME SB-163 e ASTM B163. Filo e tubo saldato vengono forniti secondo la specifica ASME o ASTM applicabile al nichel, confermata con l'ordine anzich\u00e9 dedotta dalla forma. \u00c8 il numero UNS anzich\u00e9 il nome comune a fissare la tabella di composizione sul certificato.<\/p>\n

Le gamme sopra riportate costituiscono la gamma di fornitura di Beiyu Titanium e non indicano che ogni stato metallurgico e superficie sia disponibile per ogni dimensione; la combinazione ordinata viene confermata in fase di offerta.<\/p>","link":"https:\/\/beiyutitanium.com\/it\/product-category\/woo-products\/nickel-and-nickel-based-alloys\/pure-nickel\/","name":"Nichel puro","slug":"pure-nickel","taxonomy":"product_cat","parent":112,"meta":{"_templately_pack_id":"","_templately_imported_at":"","_templately_source":"","_templately_import_session_id":""},"menu_order":0,"yoast_head":"\nPure Nickel Supplier | Nickel 200 & 201 Bar & Tube | Beiyu<\/title>\n<meta name=\"description\" content=\"Commercially pure nickel - Nickel 200 and Nickel 201 (UNS N02200 \/ N02201) - in bar, sheet, plate and tube for caustic, chloride and electronic service.
