TA2 Industrial titanium tube
Gr2 titanium pipe is an unalloyed commercial pure titanium, with a titanium purity of ≥ 99.0% and an oxygen content controlled within 0.25%. Compared to Gr1 (TA1), it has higher strength and still excellent plasticity, taking into account forming, welding, and corrosion resistance. It is the most commonly used pure titanium pipe material in the fields of chemical engineering, marine, and medical, and can be used for precision capillaries, heat exchange tubes, and fluid transportation tubes.
Gr2 = UNS R50400, which corresponds to TA2 industrial pure titanium in China standards. It is the most widely used commercial pure titanium pipe material, and the common standards it follows are ASTM B338 and ASTM B861.
It comes in two types: seamless tubes and welded tubes.

-
Exceptional corrosion resistance
surface self-passivating TiO₂ protective film, far superior to 316L stainless steel in chloride ion environments (seawater, salt water), no point corrosion, stress corrosion cracking Alleima
-
Exceptional corrosion resistance
argon arc welding is easy to form, the weld corrosion performance is basically the same as the base material
-
Stable low-temperature performance, does not brittle at low temperatures
argon arc welding is easy to form, the weld corrosion performance is basically the same as the base material
-
Lightweight
density is only 4.51g/cm³, about 40% lighter than steel,Stable low-temperature performance, does not brittle at low temperatures
Product disadvantages
1. Medium strength: much lower than TC4 titanium alloy, not suitable for high-load bearing structural pipelines
2.Not resistant to hydrofluoric acid, concentrated reducing hydrochloric acid, hot strong alkali, these media will quickly destroy the passivating film and corrode the titanium material
3. Low thermal conductivity, the heat exchange efficiency of heat exchangers is not as good as copper
4. Poor wear resistance, prone to wear in fluid with hard particles flushing conditions
5. Easily brittle at high temperatures, welding and hot processing must be strictly protected by argon gas; the long-term operating temperature is generally not more than 350℃
6. High material and processing costs, the price is much higher than stainless steel
The main applications of titanium tubes in medical device pipelines are divided into two categories:
1. Extracorporeal equipment fluid pipelines (the most common)
Surgical equipment flushing pipelines, cooling pipelines, medical gas circuits, endoscope instrument sheaths, ultrasonic scalpels / power instruments' built-in fluid channels; they can be repeatedly sterilized at high temperatures and high pressures (steam, ethylene oxide), non-magnetic, and do not cause artifacts or heating risks in a magnetic field environment.
2. Minimally invasive, temporary contact type fittings
Catheter sheaths, guide wire core tubes, biopsy instrument sleeves, minimally invasive instrument working channels; thin-walled precision small tubes, requiring resistance to bending, not easy to kink (kink resistance), and having certain X-ray imaging ability.
3. Implantation type pipelines (long-term in the body)
Dental abutment internal channels, craniofacial, spinal implant components' built-in fluid / ventilation micro-tubes; requiring long-term compatibility with human body fluids, no ion excretion, stable bone integration.
Core advantages: stable titanium passivation film, resistant to body fluid corrosion, non-magnetic, repeatable sterilization, biocompatible.
Common industrial Gr2 titanium tubes: Can only be used for extracorporeal medical device tubing (no long-term contact with human tissues, not implanted). The impurity control, surface cleanliness, non-metallic inclusions, and packaging traceability do not meet the requirements of medical device regulations. They must not be used directly as implant materials.
• ASTM F67 Gr2 (medical grade TA2): Is a compliant implant grade, with balanced strength and plasticity. It is a very common pure titanium grade used in medical device tubing and is suitable for most tubes in contact with the human body, for short-term / permanent implantation.
