316Ti seamless tube, also known as UNS S31635, is a titanium-stabilised austenitic stainless steel tube. The addition of titanium reacts with carbon and prevents carbide precipitation. This makes the tube resistant to intergranular corrosion.
ASTM A213 Stainless Steel 316Ti Seamless Tube Manufacturer
We, Zhejiang Xintongda Special Steel (XTD), are a leading Stainless steel 316Ti seamless tube manufacturer in China and a global supplier. TP316Ti seamless tube is an austenitic stainless steel grade We stabilised by titanium additions (5 × (C+N) min, 0.70% max) manufacture this tube in compliance with the ASTM A213, A269, A511, EN 10216-5 standards for high-temperature service. Unlike grades 316 and 316L, this titanium-stabilised austenitic stainless steel offers superior stress-rupture strength at elevated temperatures (approximately 425°C to 815°C / 900°F to 1500°F) The titanium content prevents chromium carbide precipitation. This ensures that the 316Ti SS tube highly resists intergranular corrosion when it is heated or welded. These special features make it a preferred option over 316L, especially for superheaters and heat exchangers. Our stainless 316Ti seamless tube is used in chemical processing and marine engineering due to its excellent durability. We ensure every SS 316Ti tube undergoes strict quality checks before delivery. We also hold multiple international certifications. As a reliable Stainless steel 316Ti tube supplier, we supply these tubes within a week for stock orders.

Manufacturing Process of 316Ti Stainless Steel Tube
The manufacturing of 316Ti stainless steel tube starts by heating a high-quality steel billet and piercing it to create a hollow shell. Then, this tube is cold-drawn or cold-rolled to achieve the precise size and a smooth surface finish. Lastly, the tube is solution annealed and then pickled to provide optimal mechanical properties and corrosion resistance. Refer to this page to know more about our detailed manufacturing process of seamless tubes.
What are the Key Features of SS 316Ti Seamless Tube?
The stainless steel 316Ti tube has 4 main characteristics. These are superior corrosion resistance, formability, resistance to sensitisation, and excellent weldability.
- Superior Corrosion Resistance: Our tube contains molybdenum (2.0–3.0%) and titanium to resist pitting and crevice corrosion. It performs exceptionally well in harsh environments like chloride solutions and acidic industrial settings.
- Formability: The austenitic structure allows our tube to be easily bent or formed into complex configurations. This flexibility is crucial for creating specialized piping systems without cracking or damaging the tube.
- Resistance to Sensitisation: When heated, titanium reacts with carbon and nitrogen to form stable titanium carbides and carbonitrides, preventing chromium carbide precipitation at grain boundaries. This prevents intergranular corrosion during high heat.
- Excellent Weldability: Our TP316Ti seamless tube is designed for easy welding using all standard fusion and resistance methods. Low carbon levels and titanium stabilisation ensure the joints remain tough and resistant to corrosive attacks.

What Industries Commonly Use SS 316Ti Tubes?
6 industries commonly use SS 316Ti tubes. These include:
Petrochemical
This tube is used in refineries to transport hot fluids and gases safely. It resists the high temperatures and sulfur compounds found during the oil refining process.
Pulp and Paper Production
ASTM A213 TP316Ti tubes in this industry handle aggressive bleaching chemicals and organic acids during the digestion process. Our 316Ti tubes prevent localised corrosion in these wet and highly acidic environments.
Coastal and Marine Environments
This tube is essential for offshore platforms and desalination plants exposed to salt spray. The tube resists salt-induced pitting, ensuring a long lifespan for underwater and deck equipment.
Chemical Processing
Reactors and pipelines use these tubes to manage the flow of highly corrosive chemical reagents. Titanium stabilisation in our tubes prevents sensitisation and intergranular corrosion when processing chemicals at elevated temperatures.
Pharmaceutical
The TP316Ti tube is used in a sterile tubing system to keep medicines pure while being made. Its smooth, low-roughness surface minimises bacterial adhesion and biofilm formation, and it withstands repeated cleaning with aggressive sanitising agents.
Oil & Gas
Heat exchangers, condensers and subsea flowlines rely on this tube to withstand high pressure and sour gas. The tube provides the necessary strength and resistance to cracking in deep-sea extraction projects.
