In the global stainless steel landscape compliant with ASTM A240/A240M, EN 10088-2/EN 10095, and ASME SA240/SA240M standards, EN/DIN 1.4571 (X6CrNiMoTi17-12-2) is the European equivalent to AISI 316Ti (UNS S31635), a titanium-stabilized austenitic grade renowned for superior intergranular corrosion (IGC) resistance in high-temperature and welded applications.
As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of 1.4571 / AISI 316Ti stainless steel, meeting both ASTM A240/A240M and EN 10088-2 specs for plates and sheets, to industries like petrochemical, pharmaceutical, and marine.
If you're cross-referencing EN/DIN 1.4571 and AISI 316Ti under ASME SA240/SA240M for a welded reactor or heat exchanger where dual certification, traceability, and performance are key, this guide provides a comprehensive comparison. We'll explore their equivalence, properties, and insights, based on ASTM A240/A240M, EN 10088-2/EN 10095, and ASME SA240/SA240M standards and our mill data.
From our production lines, we've seen the equivalence in action: In a 2024 German chemical project, our 1.4571 / AISI 316Ti plates under ASTM A240 /A240M and EN 10088-2 passed dual A262 Practice E and EN ISO 3651-2 tests with zero IGC at 650°C, enabling seamless EU/US compliance and saving 20% on recertification, as per client audits. Compliant with ASME SA240/SA240M for pressure apps, 1.4571 / AISI 316Ti's density of 8.00 g/cm³ supports universal designs. Let's delve into EN/DIN 1.4571 vs AISI 316Ti, from composition to applications, to guide your global sourcing.
EN/DIN 1.4571 (X6CrNiMoTi17-12-2)is fully equivalent to AISI 316Ti (UNS S31635) under ASTM A240/A240M, EN 10088-2/EN 10095, and ASME SA240/SA240M, sharing identical chemistry (C 0.08% max, Cr 16-18%, Mo 2-3%, Ni 10-14%, Ti 0.70% max), mechanicals (tensile 515 MPa min, yield 205 MPa min), and PREN 23-28. Density 8.00 g/cm³, IGC resistance at 425-815°C. Gangsteel offers dual-cert stock for seamless EU/US use.
The chemical composition of 1.4571 and AISI 316Ti is harmonized for full equivalence.
