In recent years, with the rapid development of aerospace, chemical engineering, Marine engineering and other fields, titanium tubes have become key materials due to their excellent properties of light weight, high strength and corrosion resistance. There are numerous grades of titanium tubes, each with its own characteristics in terms of composition, performance and application scenarios, providing diversified choices for various industries.
National standard grade
TA0: It belongs to industrial pure titanium, featuring good corrosion resistance and certain strength, with relatively low impurity content. It is often used in special occasions where high purity of materials is required, such as some high-end electronic and chemical fields.
TA1: It is also industrial pure titanium, with a slightly higher strength than TA0. It features excellent toughness and weldability, and is widely used in aerospace, chemical engineering, medical care and other fields. For instance, it can be used to manufacture hydraulic system pipes for aircraft, some corrosion-resistant pipes in chemical plants, and certain components in medical equipment.
TA2: One of the most widely used grades of industrial pure titanium, it has moderate strength and corrosion resistance, and good comprehensive performance. It can be used to make pipes for equipment such as heat exchangers, condensers, and evaporators, and has extensive applications in industries such as petrochemicals, power, and seawater desalination.
TA9: It usually contains a small amount of palladium and has excellent corrosion resistance, especially performing well in some highly corrosive media, such as high-temperature and high-concentration acidic solutions. It is often used in industries with extremely high requirements for corrosion resistance, such as chemical engineering and pharmaceuticals.
TA10: Its main alloying elements are molybdenum and nickel. Its corrosion resistance and strength have been further enhanced. It can work stably for a long time in corrosive environments such as seawater and chlorides. It is widely used in Marine engineering, shipbuilding and other fields, such as the seawater cooling system pipes of ships and the oil and gas pipes of offshore platforms.
TC4: This is a typical α+β titanium alloy, featuring high strength, good toughness and fatigue resistance. After appropriate heat treatment, its mechanical properties can be further enhanced. In the aerospace field, it is often used to manufacture key parts such as structural components and engine components of aircraft. At the same time, it also has important applications in medical devices, the automotive industry and other fields.
American brand number
Gr1: Corresponding to TA1 in the national standard, it is a commercial pure titanium with excellent corrosion resistance, plasticity and weldability, and is widely used in various occasions that require corrosion resistance and certain strength.
Gr2: Equivalent to TA2 in the national standard, it slightly differs from Gr1 in terms of strength and corrosion resistance, and can meet a wider range of engineering application requirements, such as pipeline systems in chemical equipment, Marine engineering and other fields.
Gr5: Corresponding to TC4 in the national standard, is a high-strength titanium alloy with excellent comprehensive performance. It has significant applications in high-precision and advanced fields such as aerospace and national defense, for instance, in the manufacturing of key components like aircraft frames and landing gears.
Gr7: Similar to TA9 in the national standard, it incorporates palladium, significantly enhancing its corrosion resistance in reducing media. It is commonly used in equipment and pipelines with extremely high corrosion resistance requirements in industries such as chemical engineering and food processing.
Gr12: Corresponding to TA10 in the national standard, its corrosion resistance and strength stand out among American standard titanium alloys. It is particularly suitable for Marine environments and some industrial fields with strong corrosiveness, such as seawater desalination equipment and piping systems of Marine vessels.
The refined development of titanium tube grades not only reflects the progress of materials science, but also indicates the urgent demand of industrial technology for high-performance materials. From basic pure titanium to multi-element alloys, titanium tubes are providing solid support for global high-end manufacturing in a "tailor-made" manner.
