    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

    Tensile strength of titanium alloy reaches 686–1176 MPa, with density only ~60% of steel — delivering exceptional specific strength.

    🛡️

    Superior Corrosion Resistance

    Forms a thin, dense oxide film rapidly below 550°C, outperforming most stainless steels in atmosphere, seawater, nitric acid, sulfuric acid, and strong alkali.

    🏥

    Biocompatible

    Fully tolerated by the human body and nonmagnetic — an increasingly critical property as MRI usage grows in medical diagnostics.

    🔩

    The hardness of titanium alloy (annealed) is HRC 32–38. Just as there are different grades of stainless steel and copper, titanium tube comes in many grades to suit different applications.

    📋 ASTM Standards for Titanium Grades

    ASTM provides a variety of standards relating to the "recipes" for titanium grades used in different applications, including:

    • ASTM B338 / ASME SB338
    • ASTM B265 / ASME SB265
    • ASTM B348 / ASME SB348
    • ASTM B381 / ASME SB381

    Common unalloyed and alloyed titanium grades:

    GR1 GR2 GR5 GR7 GR9 GR12

    Frequently Asked Questions

    What are the main advantages of titanium tubes over stainless steel tubes?
    Titanium tubes offer a superior strength-to-weight ratio — the density is only about 60% of steel while maintaining tensile strength of 686–1176 MPa. They also provide better corrosion resistance in oxidizing media such as seawater, nitric acid, sulfuric acid, and strong alkali environments where stainless steel may fail.
    What industries commonly use titanium tubes?
    Titanium tubes are widely used in heat exchange equipment (tubular heat exchangers, condensers, evaporators), nuclear power plants, chemical processing, marine engineering, aerospace, and medical devices. Their biocompatibility and nonmagnetic properties make them especially valuable in medical applications.
    What ASTM standards apply to titanium tubes?
    The principal ASTM standards for titanium tubes and related products are ASTM B338/ASME SB338, ASTM B265/ASME SB265, ASTM B348/ASME SB348, and ASTM B381/ASME SB381. These standards define the chemical composition and mechanical property requirements for each titanium grade.
    What is the difference between titanium Grade 1 and Grade 2 tubes?
    Grade 1 is the purest and most ductile form of unalloyed titanium, with a minimum tensile strength of 240 MPa and 24% elongation — ideal for applications requiring maximum formability. Grade 2 offers higher strength (345 MPa minimum) with 20% elongation and is the most commonly used grade, balancing strength, weldability, and corrosion resistance.
    Why is titanium tube used in medical devices?
    Titanium is biocompatible, meaning the human body tolerates it without adverse reactions. It is also nonmagnetic, which is critical as MRI (magnetic resonance imaging) becomes increasingly common in medical diagnostics. Implants and instruments made from titanium tube do not interfere with MRI scans.
    Which titanium grade has the highest tensile strength?
    Among the grades listed, Grade 5 (Ti-6Al-4V) has the highest tensile strength at a minimum of 895 MPa (130 Ksi) with a minimum yield strength of 828 MPa. It is the most widely used titanium alloy in aerospace and high-performance structural applications.
