Daxun Alloy's pure titanium Grade 1 titanium tubes include:
Our premium seamless and welded Grade 1 titanium tubes boast exceptional ductility and cold formability, making them perfect for deep drawing applications. Renowned for their excellent general and seawater corrosion resistance, these tubes also exhibit outstanding durability in oxidizing, neutral, and slightly reducing media-including chlorides.
With half the density of nickel-based alloys, titanium is synonymous with high strength, light weight, and superior corrosion resistance. This makes it the ideal choice for demanding chemical environments. Our tubes adhere to rigorous 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)
Grade 2 titanium tubes are the preferred choice for industrial applications, offering a harmonious blend of moderate strength and reasonable ductility. These tubes deliver superior corrosion resistance in both highly oxidizing and slightly reducing environments, including chlorides. They are extensively used in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, CPI equipment, and piping.
Fabrication
Titanium Grade 2 is highly responsive to cold forming with standard techniques. It is easily machinable, though maintaining sharp tools and a liberal use of coolant is crucial. Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds.
Stock Availability
Daxun Alloys maintains an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet your specific requirements.
Weight Reduction
CP 2 grade titanium tubes are renowned for their low density and exceptional strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, provided inert gas shielding is used to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube features an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. At around 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. The transition temperature can vary with impurities or alloying elements, creating distinct alpha and beta transformation zones. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) for alpha and 913°C (1675°F) for beta.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are crafted from hollow blanks via hot extrusion or oblique rolling and piercing, followed by multiple cold rolling stages. The seamless manufacturing process ensures continuous perimeters at all stages. Key steps include: sponge titanium vacuum arc melting, hot extrusion or oblique rolling + piercing, multiple cold rolling, online annealing and straightening, vacuum annealing, and final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium welded pipe is meticulously crafted from annealed flat-rolled steel plates or steel strips, utilizing the state-of-the-art automatic arc welding (TIG) process. Our comprehensive production process encompasses: titanium plate 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. Ensuring superior quality, our welded pipes undergo at least one stress relief heat treatment post forming and welding. Note: Daxun employs any filler materials during the welding process.

Experience the unique properties of our DAXUN Ti-6Al-4V Titanium Tube, Grade 5. This titanium tube, even when annealed, is challenging to form at room temperature. However, severe forming operations such as bending or stretching can be effectively executed at elevated temperatures up to 1,200°F (649°C) without altering its mechanical integrity. For precision hot sizing or forming, creep forming at temperatures between 1,000 to 1,200°F (538 to 649°C) is highly effective.
Machinability
Our DAXUN Ti-6Al-4V Titanium Tube, Grade 5, excels in machinability. Utilizing techniques akin to those for austenitic stainless steels, this tube can be machined with slow speeds, high feeds, and robust tool rigidity. To ensure optimal results, ample amounts of non-chlorinated cutting fluids are recommended.
Weldability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 is highly weldable whether in the annealed or solution and partially aged states. Post-weld heat treatment is essential for achieving desired aging properties.
Special care must be taken to prevent contamination with oxygen, nitrogen, and hydrogen. Fusion welding is best performed in an inert gas-filled chamber or with an inert gas tail shield over the molten metal and adjacent hot zones. Seamless welds can also be achieved with spot welding, seam welding, and flash welding without a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 requires careful handling to avoid contamination during processes such as pickling, forging, heat treating, and brazing. Exposure to hydrogen, oxygen, nitrogen, and carbon can significantly impair its ductility, notch sensitivity, and formability.
