Conforming to standards: ASTM B338 | ASTM B265 | ASME SB265 | ASTM F67 | ISO 5832-2 | 3.7025 | UNS R50250.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Grade 2 titanium tubes are the industry favorite for their exceptional balance of moderate strength and reasonable ductility. These tubes offer unparalleled corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. They are ideal for use in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, and beyond, where both strength and formability are paramount.
Fabrication
Titanium Grade 2 excels in cold forming using standard methods. It can be readily machined, albeit requiring sharp tools and liberal use of coolant for optimal results. Similar to machining austenitic stainless steels, deep, continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Daxun Alloys offers a wide range of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes.
Weight Reduction
CP 2 grade titanium tubes are characterized by their low density and high strength-to-weight ratio, making them ideal for applications necessitating weight reduction without compromising strength. They are cold-formable, possess excellent ductility, and can be welded using conventional TIG and MIG processes, with inert gas shielding to avoid weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. At approximately 885°C [1625°F], it transitions to a beta (body-centered cubic) structure. This transformation temperature can vary based on impurities or alloying additions. The addition of alloying elements further divides the single equilibrium transformation temperature into two zones: the alpha transformation zone below, and the beta transformation zone above. In between, both alpha and beta phases 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
Daxun's ASTM B338 Grade 2 titanium seamless tubes are crafted from hollow blanks via the hot extrusion process or oblique rolling and piercing, followed by multiple cold rolling stages. The continuous perimeter is maintained throughout the manufacturing process.

Forgeability/Formability The DAXUN Ti-6Al-4V Titanium Tube, also known as Grade 5 Titanium Tube, is meticulously forged at 1,750°F (954°C), culminating in a final forging temperature of 1,450°F (788°C). For optimal results, a reduction of at least 35% is strongly recommended, ensuring superior performance and durability.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, exhibits considerable difficulty in forming at room temperature, even when annealed. Thus, severe forming operations such as bending or stretching can be effectively carried out on the annealed material at elevated temperatures up to 1,200°F (649°C) without altering its mechanical properties. Creep forming is an advantageous technique for hot sizing or forming at temperatures ranging from 1,000 to 1,200°F (538 to 649°C), enabling precise and efficient shaping.
Machinability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, can be adeptly machined using methods employed for austenitic stainless steels. Optimal machining involves slow speeds, high feeds, robust tool rigidity, and a generous application of non-chlorinated cutting fluids to ensure a smooth and efficient machining process.
Weldability The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, is readily weldable in both annealed and solution-treated, partially aged conditions. Following the welding process, aging can be accomplished during post-weld heat treatment to enhance the material's properties.
To achieve optimal weld quality, precautions must be taken to avoid contamination by oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas-filled chamber or with the use of an inert gas tail shield over the molten metal and adjacent hot zones. Moreover, spot welding, seam welding, and flash welding can be executed without the necessity of a protective atmosphere, ensuring versatility in welding applications.
Special Considerations The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, is susceptible to contamination from hydrogen during improper pickling and from the absorption of oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can significantly reduce ductility, impair notch sensitivity, and affect formability. Careful handling and processing are imperative to maintain the tube's superior qualities.
