High-Quality Titanium Tube Factory and Suppliers in China - ASTM B338 Certified
To Know About Titanium Tube
Titanium tube has the advantages of light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine tube heat exchanger, condenser, evaporator and conveying pipeline. Many nuclear power plants use titanium tube as the standard tube for their units.
⚙️
High Strength & Low Density
The tensile strength of titanium alloy is 686–1176 MPa, with a density only about 60% of steel — resulting in an exceptionally high specific strength. Hardness (annealed) is HRC32–38.
🛡️
Superior Corrosion Resistance
Below 550°C, titanium rapidly forms a thin, dense oxide film on its surface, offering better corrosion resistance than most stainless steels in oxidizing media including atmosphere, sea water, nitric acid, sulfuric acid, and strong alkalis.
📋
Multiple Grades Available
ASTM standards (ASTM B338/ASME SB338, B265/SB265, B348/SB348, B381/SB381) cover numerous titanium grades including GR1, GR2, GR5, GR7, GR9, and GR12 for different applications.
🏥
Biocompatible & Nonmagnetic
Titanium is biocompatible — the human body tolerates it well. It is also nonmagnetic, making it increasingly important as MRI usage becomes more common in medical diagnostics.

Frequently Asked Questions
❓
What are the main advantages of titanium tubes over stainless steel tubes?
Titanium tubes offer a superior strength-to-weight ratio — their density is only about 60% of steel while maintaining tensile strength of 686–1176 MPa. They also provide better corrosion resistance in oxidizing environments such as sea water, nitric acid, sulfuric acid, and strong alkalis, making them a preferred choice over stainless steel in demanding applications.
❓
What industries commonly use titanium tubes?
Titanium tubes are widely used in heat exchange equipment (tubular heat exchangers, coil heat exchangers, condensers, evaporators), nuclear power plants, chemical processing pipelines, and medical devices. Their biocompatibility and nonmagnetic properties make them especially valuable in the medical and nuclear energy sectors.
❓
What ASTM standards apply to titanium tubes?
The principal ASTM standards for titanium tubes include ASTM B338 / ASME SB338 (seamless and welded titanium tubes for condensers and heat exchangers), ASTM B265 / ASME SB265 (titanium strip, sheet, and plate), ASTM B348 / ASME SB348 (titanium bars and billets), and ASTM B381 / ASME SB381 (titanium forgings).
❓
What are the most common titanium tube grades and their differences?
Common grades include GR1 (highest ductility, lowest strength), GR2 (standard unalloyed, most widely used), GR5 (Ti-6Al-4V, highest strength at 895 MPa minimum), GR7 (palladium-added for enhanced corrosion resistance), GR9 (medium strength with good formability), and GR12 (molybdenum and nickel added for improved corrosion resistance). Each grade is suited to specific application requirements.
❓
Why is titanium tube used in medical devices?
Titanium is biocompatible, meaning the human body can safely tolerate it without adverse reactions — a critical requirement for implants and surgical instruments. Additionally, titanium is nonmagnetic, which is increasingly important as MRI (Magnetic Resonance Imaging) technology becomes more prevalent in medical diagnostics, since magnetic materials can interfere with MRI equipment.
❓
How does the corrosion resistance of titanium tubes work?
When titanium is exposed to air or oxidizing environments at temperatures below 550°C, it rapidly forms a thin, dense, and stable titanium oxide (TiO₂) film on its surface. This passive oxide layer acts as a protective barrier against further corrosion, providing excellent resistance to atmosphere, sea water, nitric acid, sulfuric acid, and strong alkalis — performance that surpasses most stainless steel grades in similar conditions.
