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 — delivering exceptional specific strength. Hardness (annealed) is HRC 32–38.

🛡️

Superior Corrosion Resistance

Below 550°C, titanium rapidly forms a thin, dense oxide film on its surface — outperforming most stainless steels in atmosphere, sea water, nitric acid, sulfuric acid, and strong alkali environments.

📋

Multiple ASTM Grades Available

Key standards include ASTM B338/ASME SB338, ASTM B265/ASME SB265, ASTM B348/ASME SB348, and ASTM B381/ASME SB381. Common grades: GR1, GR2, GR5, GR7, GR9, GR12.

🏥

Biocompatible & Nonmagnetic

Titanium is fully biocompatible and nonmagnetic — ideal for medical devices and increasingly important as MRI usage grows in modern medical diagnostics.

Another great thing about titanium is that, just as there are different types of stainless steel, copper, nickel, there are many different grades of titanium tube — each suited to specific application requirements.

Frequently Asked Questions

❓ What are the main advantages of titanium tubes over stainless steel tubes?

Titanium tubes offer a superior strength-to-weight ratio — with a density only about 60% of steel while maintaining tensile strength of 686–1176 MPa. They also exhibit exceptional corrosion resistance in oxidizing media such as sea water, nitric acid, and sulfuric acid, often outperforming most stainless steel grades in these environments.

❓ 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, aerospace, and medical device manufacturing. Their biocompatibility and nonmagnetic properties make them especially valuable in the medical sector.

❓ What ASTM standards apply to titanium tubes?

The principal ASTM standards for titanium tubes and related products include ASTM B338 / ASME SB338 (welded and seamless tubes for condensers and heat exchangers), ASTM B265 / ASME SB265 (strip, sheet, and plate), ASTM B348 / ASME SB348 (bar and billet), and ASTM B381 / ASME SB381 (forgings).

❓ What is the difference between titanium Grade 1, Grade 2, and Grade 5?

Grade 1 is the purest and most ductile form, with a minimum tensile strength of 240 MPa and 24% elongation — ideal for applications requiring high formability. Grade 2 is the most commonly used grade, offering a balance of strength and ductility (345 MPa, 20% elongation). Grade 5 (Ti-6Al-4V) is the most widely used titanium alloy, with significantly higher strength (895 MPa) suited for high-performance structural applications.

❓ Why is titanium tube used in medical devices?

Titanium is biocompatible, meaning the human body tolerates 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) becomes more prevalent in medical diagnostics, since ferromagnetic materials can pose safety risks in MRI environments.

❓ How does titanium's corrosion resistance work?

When exposed to air below approximately 550°C, titanium rapidly forms a thin, dense, and highly stable titanium oxide (TiO₂) film on its surface. This passive layer acts as a barrier against further oxidation and chemical attack, providing outstanding resistance to corrosion in oxidizing media including atmosphere, sea water, nitric acid, sulfuric acid, and strong alkalis.
