Daxun Alloy's pure titanium Grade 1 titanium tubes include:
Our seamless and welded titanium tubes exhibit outstanding ductility and cold formability, making them perfect for deep drawing applications. These Grade 1 titanium tubes are renowned for their exceptional general and seawater corrosion resistance. Additionally, they offer superior resistance to oxidizing, neutral, and mildly reducing media, including chlorides, ensuring robust performance across diverse environments.
Titanium's low density, approximately half that of nickel-based alloys, combined with its high strength, lightweight nature, and superior corrosion resistance, makes it an ideal choice for demanding chemical conditions. Our tubes adhere to the following standards: ASTM B338, ASTM B265, ASME SB265, ASTM F67, ISO 5832-2, 3.7025, and UNS R50250.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
The most widely used titanium tube for industrial purposes, Grade 2 titanium offers an optimal balance of moderate strength and good ductility. It boasts excellent corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. Ideal for the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, CPI equipment, and industrial and aerospace components, where both strength and formability are essential.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard methods. While it can be readily machined, maintaining sharp tools and liberal use of coolant is crucial. Similar to machining austenitic stainless steels, cuts should be deep and continuous with controlled feeds and speeds to ensure precision and durability.

Weight Reduction
With a low density and high strength-to-weight ratio, CP 2 grade titanium tubes are perfect for applications requiring weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes. Inert gas shielding is necessary to prevent embrittlement of the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), this structure transforms to a beta (body-centered cubic) form. The transformation temperature can vary based on impurities or alloying elements, dividing the single equilibrium transformation temperature into alpha and beta zones. Between these temperatures, both alpha and beta forms coexist. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F), respectively.
Grade 2 Titanium Seamless Pipe Manufacturing Process
At Daxun, our ASTM B338 Grade 2 titanium seamless tubes are crafted from hollow blanks using hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Each stage ensures the titanium seamless tubes maintain continuous perimeters. The process includes sponge titanium vacuum arc melting, ingot blanking, cleaning, cutting, feeding, hot extrusion or oblique rolling with piercing, degreasing, drying, cutting, online annealing, straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium welded pipe is a paragon of precision and durability. Crafted from annealed flat-rolled steel plates or strips through an automatic arc welding (TIG) process, it stands as a testament to superior engineering. The meticulous production journey encompasses uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Each welded pipe undergoes a mandatory stress relief heat treatment post-forming and welding, ensuring the utmost resilience. Notably, Daxun employs high-quality filler materials during the welding process to guarantee exceptional consistency and strength.

Forgeability/Formability The DAXUN Ti-6Al-4V Titanium Tube, often recognized as Grade 5 Titanium Tube, showcases exceptional forgeability. It undergoes forging at a precise 1,750°F (954°C) and achieves its final shape at 1,450°F (788°C). For optimal results, a minimum reduction of 35% in size is highly recommended.
The DAXUN Ti-6Al-4V Titanium Tube, or Grade 5 Titanium Tube, presents challenges in forming at room temperature, even post-annealing. However, intense forming operations like bending or stretching can be efficiently executed on annealed material at elevated temperatures up to 1,200°F (649°C) without affecting its mechanical properties. For hot sizing or shaping, creep forming at temperatures between 1,000 to 1,200°F (538 to 649°C) is advisable.
Machinability The DAXUN Ti-6Al-4V Titanium Tube, known as Grade 5 Titanium Tube, can be proficiently machined using techniques designed for austenitic stainless steels. Key practices include utilizing slow speeds, high feeds, ensuring robust tool rigidity, and applying ample quantities of non-chlorinated cutting fluids.
Weldability The DAXUN Ti-6Al-4V Titanium Tube, or Grade 5 Titanium Tube, exhibits excellent weldability in both annealed and solution-treated, partially aged states. Aging is typically completed during post-weld heat treatments.
During welding, it is crucial to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be carried out in an inert gas-filled environment or with an inert gas tail shield over the molten region and adjacent hot areas. Furthermore, spot welding, seam welding, and flash welding can be executed effectively without the necessity for a protective atmosphere.
Special Considerations The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, may be susceptible to hydrogen contamination from improper pickling and the absorption of oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. This contamination can lead to reduced ductility and negative impacts on notch sensitivity and formability.
