A European buyer sourcing titanium for chemical, marine or oil and gas service is rarely comparing like with like. One offer is written to EN and DIN with a Werkstoff number, another to ASTM with a UNS number, and the certificate line can read 2.2, 3.1 or 3.2 depending on who inspected the metal. This guide sets out how the designation systems line up, what the certificate grades actually mean, and how to compare a non-EU mill quote against European supply on the terms that matter to a process plant, not an airframe. It is written for industrial and process service; aerospace and defence sourcing sit under separate qualification regimes and are out of scope here.<\/p>\n

The same grade has three names: EN\/DIN, Werkstoff, and ASTM<\/h2>\n

The first source of confusion is that the identical metal carries different labels in different markets. A German drawing calls commercially pure Grade 2 by its Werkstoff number 3.7035; an ASTM purchase order calls it UNS R50400 to ASTM B348; both are the same CP titanium. Knowing the cross-references stops a buyer from rejecting or double-sourcing material that is actually equivalent.<\/p>\n\n\n\n\n\n\n\n\n\n\n

Product-form standards line up the same way: bar is ASTM B348 or DIN 17862, sheet and plate is ASTM B265 or DIN 17860, and tube for condensers and exchangers is ASTM B338 or DIN 17861 (seamless) \/ DIN 17866 (welded). For most CP and Ti-Pd grades the chemistry and mechanical limits across these systems are close enough that a mill can certify to both; the practical step is to name on the RFQ which standard the certificate must cite, so incoming inspection has one reference to check against.<\/p>\n

What the EN 10204 certificate number actually means<\/h2>\n

The certificate line is where a lot of European procurement risk hides, because 2.2, 3.1 and 3.2 are not quality grades of the metal, they describe who verified it.<\/p>\n\n\n\n\n\n\n\n
EN 10204 type<\/th>\nWho certifies<\/th>\nWhat it means for you<\/th>\n<\/tr>\n<\/thead>\n
2.2<\/td>\nThe manufacturer, on non-specific inspection<\/td>\nA statement of compliance, not test results tied to your batch. Rarely enough for process titanium.<\/td>\n<\/tr>\n
3.1<\/td>\nThe manufacturer's authorised inspection representative, independent of the production department<\/td>\nSpecific-inspection results for the supplied products, validated by the manufacturer’s authorised inspection representative independent of the manufacturing department. State the required document type and reporting scope in the order.<\/td>\n<\/tr>\n
3.2<\/td>\nAn independent third party or the buyer's agent, in addition to the mill<\/td>\nValidated by the manufacturer’s authorised inspection representative together with either the purchaser’s authorised inspection representative or the inspector designated by the applicable official regulations. Specified when a project or code requires that additional validation. Define witness points, reporting and schedule before order release.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

EN 10204 3.1 is commonly requested for industrial titanium when the buyer needs specific-inspection results. It is not automatic and it does not define the product’s technical delivery conditions. State the product standard, required document type, traceability and test scope in the RFQ and purchase order. If 3.2 is required, define the additional validation party, witness points, reports and schedule before order release.<\/p>\n

Comparing a non-EU mill offer against European supply<\/h2>\n

European mill supply for industrial titanium has been tight, and regional price indices in early 2026 put delivered mill-product prices in Europe well above other regions, which is what makes non-EU sourcing worth evaluating in the first place. The way to compare offers fairly is to hold everything except origin constant and look past the headline number:<\/p>\n
