In the specialized market for corrosion-resistant piping solutions, 316Ti stainless steel pipes and tubes offer exceptional performance in high-temperature and acidic environments, thanks to titanium stabilization that prevents intergranular corrosion.
As a premier producer and exporter based in China, Gangsteel maintains ready stock of seamless 316Ti pipes and tubes under standards like ASME SA312/SA213 for pipes/tubes, ASTM A312/A213 for general specs, EN 10216-5 for European norms, JIS G3459/G3463 for Japanese standards, and AISI 316Ti for American nomenclature.
If you're sourcing for a chemical processing line or marine system, our seamless stock in various sizes ensures quick availability with full compliance. This guide details specs, properties, and our inventory for 316Ti (UNS S31635, EN 1.4571), based on industry standards and our mill expertise.
From our warehouses, we've shipped seamless 316Ti pipes on demand: In Q3 2025, a U.S. pharmaceutical client received our 50mm OD stock in 10 days, enabling sterile line installation without delays, as per their feedback. Often sourced under ASTM A240 /A240M for base material or ASME SA240/SA240M for compliance, our pipes with density 8.00 g/cm³ and PREN 23-28 deliver durability. With sizes from 6mm OD (for precision tubes) to 610mm OD (for heavy pipes), Gangsteel's seamless stock meets diverse needs. Let's explore the details, from composition to sourcing, to see how our inventory can support your project.
