This page covers the common grades for titanium plate and tube (Grade 2, 5, 7), metric specification fields, how to select a grade for seawater and chemical service, and the UNS\/ASTM cross-reference and EN 10204 3.1 certificate that international procurement checks. It is written for engineering and purchasing, not consumer goods.<\/p>\n<h2>Common grades for titanium plate and tube<\/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>Werkstoff<\/th>\n<th>Characteristics and typical use<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Grade 2 (CP)<\/td>\n<td>R50400<\/td>\n<td>3.7035<\/td>\n<td>Workhorse for general chemical, seawater and heat-exchanger service; 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>3.7165<\/td>\n<td>High-strength structural parts; corrosion resistance is lower than CP, chosen for strength<\/td>\n<\/tr>\n<tr>\n<td>Grade 7 (Ti-Pd)<\/td>\n<td>R52400<\/td>\n<td>3.7235<\/td>\n<td>CP titanium plus palladium; corrosion resistance in reducing acids (HCl, H2SO4) is much wider than Grade 2<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The same grade of titanium carries different codes in different markets: UNS (R50400) and ASTM are common in international procurement, while the EN and DIN system uses a Werkstoff number (3.7035). Listing all of them lets a buyer searching by any code reach the page. The working standards are ASTM in practice: plate ASTM B265, tube ASTM B338, bar ASTM B348, and an order can also cite JIS H4600 series or CNS.<\/p>\n<h2>Selecting a grade for seawater and chemical service<\/h2>\n<p>Titanium&#8217;s corrosion resistance comes from a dense oxide film. In oxidizing and neutral media (seawater, wet chlorine, nitric acid), CP Grade 2 usually maintains a stable passive film and is the workhorse. In reducing acids (HCl, H2SO4), the film is harder to maintain, and Grade 7&#8217;s palladium widens the resistance window substantially. For hot brine and chloride crevice environments, Grade 12 is also an option. Choosing the wrong direction, such as using high-strength Grade 5 for a corrosion duty, only adds cost. The seawater and marine selection logic is in our <a href=\"https:\/\/beiyutitanium.com\/de\/titanium-seawater-corrosion-resistance\/\">titanium seawater corrosion resistance guide<\/a>; the Grade 2 chemical and heat-exchanger case is in our <a href=\"https:\/\/beiyutitanium.com\/de\/grade-2-titanium-chemical-heat-exchanger\/\">Grade 2 chemical guide<\/a>.<\/p>\n<h2>Metric specifications for RFQs<\/h2>\n<p>Taiwan and international buyers mostly search and quote by metric size. To let the mill judge manufacturability and tolerance, the RFQ should at least include these fields:<\/p>\n<table>\n<thead>\n<tr>\n<th>Form<\/th>\n<th>Metric fields to specify<\/th>\n<th>Norm<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Titanium plate<\/td>\n<td>Thickness x width x length, tolerance and surface condition<\/td>\n<td>ASTM B265<\/td>\n<\/tr>\n<tr>\n<td>Titanium tube<\/td>\n<td>Outside diameter x wall thickness x length, tolerance, seamless or welded<\/td>\n<td>ASTM B338<\/td>\n<\/tr>\n<tr>\n<td>Titanstab<\/td>\n<td>Diameter x length, tolerance and surface condition<\/td>\n<td>ASTM B348<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Material certificate: what to check on import<\/h2>\n<p>For imported industrial titanium, check the inspection document against the purchase order, ordered product standard and required document type. When EN 10204 3.1 is ordered, the document should report the specific-inspection results required for the delivered material and be validated by the manufacturer&#8217;s authorised inspection representative independent of the manufacturing department. On receipt, compare the reported chemistry with the ordered grade, confirm the mechanical results meet the ordered standard for that form and size, and match the traceability identifier on the document to the marking on the 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 international 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 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 aluminum and vanadium for high strength but lower corrosion resistance. Choose Grade 2 for corrosion duty, Grade 5 for structural strength.<\/p>\n<p><strong>Which titanium grade is used for seawater?<\/strong><\/p>\n<p>Seawater is an oxidizing, chloride-bearing environment where CP Grade 2 usually maintains a stable passive film, so it is the workhorse for seawater and marine service. Only when reducing acids or severe crevice corrosion are also present do you move up to Grade 7 (Ti-Pd) or another corrosion-upgrade grade.<\/p>\n<p><strong>What is the material certificate for imported titanium?<\/strong><\/p>\n<p>EN 10204 defines inspection-document types, not product requirements. A type 3.1 inspection certificate reports the specific-inspection results for the delivered products and is validated by the manufacturer&#8217;s authorised inspection representative independent of the manufacturing department; it does not replace ASTM B265, B338 or another product specification. State the required document type in the RFQ and purchase order, then verify that the certificate reports the results and traceability required for the ordered grade, form and size.<\/p>\n<h2>Request a quote for industrial titanium plate or tube<\/h2>\n<p>To quote industrial titanium plate or tube, Beiyu needs: grade (Grade 2\/5\/7, or the UNS\/ASTM code), form and standard, metric dimensions (plate thickness \/ tube OD x wall \/ bar diameter and tolerance), quantity, service or medium, and the required inspection-document type.

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\/4631","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=4631"}],"version-history":[{"count":1,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/4631\/revisions"}],"predecessor-version":[{"id":4647,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/posts\/4631\/revisions\/4647"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/media\/4736"}],"wp:attachment":[{"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/media?parent=4631"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/categories?post=4631"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beiyutitanium.com\/de\/wp-json\/wp\/v2\/tags?post=4631"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
