ASTM A312 TP316Ti Stainless Steel Pipe is a titanium-stabilized austenitic stainless steel pipe specifically designed for high-temperature and corrosion-resistant environments. Compared with standard 316 and 316L stainless steel, 316Ti contains titanium, which effectively prevents chromium carbide precipitation during welding and long-term exposure to elevated temperatures.
As a professional stainless steel supplier, we provide ASTM A312 TP316Ti seamless and welded stainless steel pipes along with AISI standard bending, welding, cutting, polishing, threading, and custom fabrication services. Our products are widely used in petrochemical plants, chemical processing, heat exchangers, power generation, offshore engineering, food processing, pharmaceutical manufacturing, and pressure piping systems.
Titanium stabilization allows TP316Ti pipes to maintain excellent mechanical properties at temperatures up to 800°C, making them suitable for continuous high-temperature service.
Superior Corrosion Resistance
Excellent resistance to pitting corrosion
Outstanding resistance to crevice corrosion
Strong resistance to chloride environments
Good oxidation resistance
Suitable for marine and chemical industries
Excellent Weldability
316Ti can be welded using conventional welding methods without significant sensitization, making it ideal for fabricated piping systems.
Long Service Life
The combination of molybdenum and titanium provides outstanding durability in aggressive environments, reducing maintenance costs and extending equipment lifespan.

Frequently Asked Questions
What is ASTM A312 TP316Ti stainless steel pipe?
ASTM A312 TP316Ti is a titanium-stabilized austenitic stainless steel pipe designed for high-temperature and corrosive environments. Titanium minimizes carbide precipitation, improving weldability and resistance to intergranular corrosion.
What is the difference between 316Ti and 316L?
316Ti contains titanium for enhanced stability at elevated temperatures, while 316L has lower carbon content and is preferred for general corrosion resistance. For prolonged service above 500°C, 316Ti is generally the better choice.
Can TP316Ti stainless steel pipe be welded?
Yes. TP316Ti offers excellent weldability using TIG, MIG, orbital, and other conventional welding methods. In many applications, no post-weld heat treatment is required.
Is 316Ti suitable for marine applications?
Yes. With molybdenum and titanium additions, 316Ti provides excellent resistance to chloride-induced corrosion, making it suitable for marine and offshore environments.
Do you provide custom fabrication services?
Yes. We offer cutting, bending, welding, polishing, threading, machining, and complete stainless steel fabrication services according to customer drawings and project requirements.
