Grade 9 Titanium Alloy Pipe Manufacturer - Daxun Alloy
Provide High Quality Grade 9 Titanium Pipe to Customers Around The World
Grade 9 titanium pipe is a versatile alpha-beta alloy (Ti-3Al-2.5V), offering an optimal balance between pure titanium’s formability and Grade 5’s strength. It features moderate strength, exceptional weldability, and outstanding corrosion resistance in diverse environments. Its density (4.48 g/cm³) is approximately 60% that of steel, yet it delivers strength comparable to some steels, making it ideal for weight-sensitive applications. The alloy excels in durability across harsh conditions, including seawater, chemical processing, and extreme temperatures, while maintaining excellent fracture toughness and fatigue resistance.
Where is Grade 9 titanium pipe used?
In aerospace, it’s used for hydraulic and fuel lines, ducting systems, and airframe components—reducing weight without sacrificing structural integrity. Instalações de processamento químico rely on it for heat exchangers, reactor tubing, and piping systems handling corrosive acids, alkalis, and chlorides due to its inertness. Marine and offshore industries use it for seawater cooling systems, desalination plants, and subsea equipment, leveraging its unparalleled seawater corrosion resistance. Oil and gas operations employ it in downhole tubing, risers, and Christmas tree components for high-pressure sour gas environments. Additionally, sports equipment manufacturers utilize it for high-performance bicycle frames, golf shafts, and racing components, where its strength-to-weight ratio and fatigue resistance are critical. It also serves in power generation (condenser tubing) and industrial heat transfer systems, combining longevity with thermal efficiency.
Key Performance:
Strength-Ductility Balance:
- Tensile Strength: 620 MPa (annealed state) – Lower than Grade 23 but 30% stronger than pure titanium (Grade 1-4).
- Elongation: ≥15% – Superior ductility vs. Grade 5 (≥10%), enabling complex forming and high fatigue resistance.
- Density: 4.48 g/cm³ – 60% lighter than steel, ideal for weight-sensitive applications.
Corrosion Resistance:
- Resists pitting/crevice corrosion in seawater, chlorides, and acidic/alkaline environments (e.g., HCl, H₂SO₄).
- Outperforms stainless steel in marine/chemical processing, with no galvanic corrosion risk.
Weldability & Processability:
- Welding: Exceptional compatibility with TIG, laser, and electron-beam welding – minimal post-weld cracking risk.
- Forming: Cold-workable into tubes, sheets, and complex shapes; machinability comparable to Grade 5.
- Heat Treatment: Stress-relieved at 480–650°C to optimize mechanical properties.
Application Advantages:
- Aeroespacial: Hydraulic tubing, ducting – weight reduction without sacrificing fatigue life.
- Marine: Heat exchangers, desalination plants – seawater immunity extends service life.
- Chemical: Reactors, piping systems – handles sour gas (H₂S) and strong acids.
- Industrial: High-pressure cylinders, sports equipment (bike frames, golf shafts) – lightweight durability.

-
Titanium seamless tubes are made by piercing and drawing solid titanium bars, and the hollow part of the tube is made by piercing or hot extrusion. Titanium seamless tubes are ideal for very large diameter to wall thickness ratios and have very good external dimensional tolerances.
-
Titanium welded pipe is a tubular product made of strip titanium that is roll formed and fusion welded along the longitudinal seam. The welding process used by Daxun Alloy does not use any filler metal during the welding process.
-
Titanium square tubes are drawn from round tubes or round tube billets and can be formed into right angles or rounded corners. They can also be cold extruded, which is efficient and low cost. The only disadvantage is that the tolerance will gradually increase.
-
Tubular products are welded and then re-drawn to final size. Welding and drawing is ideal for producing thick walled, large diameter tubes that cannot be welded directly to size but still offer cost savings over seamless tubes. All Daxun welded and drawn tubes are bright annealed.

Na DAXUN, oferecemos uma vasta gama de graus de liga de titânio, do grau 1 ao grau 12.
Os graus 1-4 são titânio puro, enquanto os graus superiores são ligas.
Os tipos de liga são populares pela sua elevada relação resistência/peso.
O grau de liga de titânio mais utilizado que encontramos é o grau 5. Embora continue a ser rica em titânio, esta classe é uma das mais fiáveis porque pode suportar temperaturas até 600°F e resistir a condições extremas.
As qualidades superiores são preferidas por indústrias como a aeroespacial e a marítima devido à sua resistência ao desgaste e à corrosão.
Por outro lado, os graus inferiores são utilizados principalmente para soldadura devido à sua menor resistência.
