This page covers titanium electrodes (including platinum-coated), titanium tube and titanium plate in the common grades (Grade 2, 5, 7), metric RFQ fields, the UNS\/ASTM cross-reference and the EN 10204 3.1 material certificate. It is written for engineering and purchasing, not consumer goods.<\/p>\n<h2>Titanium electrodes and platinum-coated titanium anodes<\/h2>\n<p>Titanium is a common substrate for electrodes in electrochemical processing, electroplating and cathodic protection, because it can hold a protective oxide film in many chloride-bearing environments. The coating decides the function: a platinum-coated titanium anode is used for plating and electrolysis, while an MMO (mixed metal oxide, for example Ru-Ir) anode is used for chlor-alkali production and cathodic protection.<\/p>\n<ul>\n<li><strong>Platinum-coated titanium anode<\/strong> for electroplating and electrolysis, see <a href=\"https:\/\/beiyutitanium.com\/de\/product\/platinum-plated-titanium-anode\/\">platinum-plated titanium anode<\/a>.<\/li>\n<li><strong>MMO Ru-Ir anode<\/strong> for chlor-alkali and cathodic protection, see <a href=\"https:\/\/beiyutitanium.com\/de\/product\/ru-ir-titanium-anodes\/\">Ru-Ir titanium anode<\/a>.<\/li>\n<\/ul>\n<p>The electrode substrate is usually titanium plate or bar in Grade 1 or Grade 2; the coating is specified separately for the electrochemical environment.<\/p>\n<h2>Common grades for tube and plate<\/h2>\n<p>Industrial titanium is mostly commercially pure titanium and a few alloys, chosen by corrosion and strength need, not by picking the highest grade.<\/p>\n<table>\n<thead>\n<tr>\n<th>G\u00fcte<\/th>\n<th>UNS<\/th>\n<th>Characteristics and use<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Grade 2 (CP)<\/td>\n<td>R50400<\/td>\n<td>Workhorse for chemical, seawater and heat exchangers; good corrosion resistance, easy to weld and form<\/td>\n<\/tr>\n<tr>\n<td>Grade 5 (Ti-6Al-4V)<\/td>\n<td>R56400<\/td>\n<td>High strength for structural parts; corrosion resistance lower than CP<\/td>\n<\/tr>\n<tr>\n<td>Grade 7 (Ti-Pd)<\/td>\n<td>R52400<\/td>\n<td>CP titanium plus palladium; reviewed when better corrosion resistance than Grade 2 is needed in reducing acids such as HCl or H2SO4<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Standards by form: plate ASTM B265, tube ASTM B338, bar ASTM B348; the EN 10204 3.1 certificate is used across international markets.<\/p>\n<h2>How to write metric RFQ dimensions<\/h2>\n<p>Vietnamese buyers mostly search and quote by metric size (diameter, thickness). To let a supplier check the standard, tolerance and manufacturing route, write the following fields instead of only &quot;titanium tube&quot; or &quot;titanium plate&quot;:<\/p>\n<table>\n<thead>\n<tr>\n<th>Form<\/th>\n<th>RFQ fields to provide<\/th>\n<th>Norm<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Titanium tube<\/td>\n<td>outside diameter (OD\/phi), wall thickness, length, seamless or welded, tolerance<\/td>\n<td>ASTM B338<\/td>\n<\/tr>\n<tr>\n<td>Titanium plate<\/td>\n<td>thickness, width x length, tolerance, surface condition and quantity<\/td>\n<td>ASTM B265<\/td>\n<\/tr>\n<tr>\n<td>Titanstab<\/td>\n<td>diameter, length, material condition, tolerance and surface condition<\/td>\n<td>ASTM B348<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For seawater and chemical duty, the grade-selection logic is in our <a href=\"https:\/\/beiyutitanium.com\/de\/titanium-seawater-corrosion-resistance\/\">seawater corrosion resistance guide<\/a>.<\/p>\n<h2>Material certificate: what to check on import<\/h2>\n<p>For titanium electrode, tube and plate deliveries, read the inspection document against the purchase order, the ordered product standard and the document type that was actually specified. An EN 10204 3.1 certificate reports specific-inspection results for the supplied material and is validated by the manufacturer&#8217;s authorised inspection representative independent of the manufacturing department. The traceability identifier must connect the document to the supplied material. If 3.2 or other independent inspection is required, define the responsible parties, witness points, reports and schedule in the RFQ. The full field list for RFQs is in our <a href=\"https:\/\/beiyutitanium.com\/de\/titanium-bar-rfq-checklist\/\">Checkliste f\u00fcr Titanstab-Anfragen<\/a>.<\/p>\n<h2>H\u00e4ufig gestellte Fragen<\/h2>\n<p><strong>What is a platinum-coated titanium anode used for?<\/strong><\/p>\n<p>The titanium substrate stays stable in a chloride-bearing electrochemical environment, while the platinum coating provides the anode surface for electroplating and electrolysis. For chlor-alkali production and cathodic protection, an MMO Ru-Ir anode is usually used instead of platinum.<\/p>\n<p><strong>What is the difference between titanium Grade 2 and Grade 5?<\/strong><\/p>\n<p>Grade 2 is commercially pure titanium, with good corrosion resistance and moderate strength, and is the workhorse for seawater and chemical service; Grade 5 (Ti-6Al-4V) adds aluminium and vanadium for high strength but lower corrosion resistance. Choose Grade 2 for corrosion duty, Grade 5 for structural strength.<\/p>\n<p><strong>What is the EN 10204 3.1 material certificate?<\/strong><\/p>\n<p>EN 10204 sets out inspection-document types; it does not state product requirements. A type 3.1 certificate supplies the specific-inspection results for the delivered products under the manufacturer&#8217;s independent inspection representative, and it sits alongside the governing product specification rather than replacing it. Name the document type in the RFQ and purchase order, then check that the issued certificate carries the results and traceability the ordered material, form and size require.<\/p>\n<h2>Request a quote for titanium electrodes, tube or plate<\/h2>\n<p>To quote industrial titanium, Beiyu needs: grade (Grade 2\/5\/7, or the UNS\/ASTM code), form and standard, metric dimensions (tube OD x wall \/ plate thickness \/ bar diameter), quantity, service or medium, the coating type if an electrode, and the required inspection-document type. State any EN 10204 3.1 or 3.2 document, test, validation and heat-traceability scope in the RFQ so Beiyu can confirm it before order release. <a href=\"https:\/\/beiyutitanium.com\/de\/contact\/\">Kontaktieren Sie Beiyu Titanium f\u00fcr eine Anfrage.<\/a><\/p>\n<\/div>\n<section class=\"beiyu-author-bio\" data-codex-c44-author-bio=\"penn-ma\">\n<h2>\u00dcber den Autor<\/h2>\n<p><strong>Penn Ma<\/strong> hat 15 Jahre Titanexport bei Beiyu Titanium hinter sich und pr\u00fcft dort Titan- und Nickellegierungs-Anfragen, Grade-Auswahl, Zeugnisumfang und norm\u00fcbergreifende Bezeichnungen selbst.

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. 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\/"}]}},"_links":{"self":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/4628","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=4628"}],"version-history":[{"count":1,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/4628\/revisions"}],"predecessor-version":[{"id":4648,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/4628\/revisions\/4648"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/media\/4737"}],"wp:attachment":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/media?parent=4628"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/categories?post=4628"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/tags?post=4628"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
