Daxun Alloy's Superior Pure Grade 1 Titanium Tubes:
Available in seamless and welded forms, our Grade 1 titanium tubes boast excellent ductility and cold formability, making them ideal for deep drawing applications. These tubes offer remarkable general and seawater corrosion resistance, as well as superb resistance to oxidizing, neutral, and slightly reducing environments, including chlorides.
Titanium's unique properties, such as low density (about half that of nickel-based alloys), high strength, lightweight, and exceptional corrosion resistance, make it the perfect choice for challenging chemical environments. 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)
Our Grade 2 titanium tubes are the go-to choice for industrial applications, offering an excellent balance of moderate strength and reasonable ductility. They excel in highly oxidizing and slightly reducing conditions, including chlorides. Ideal for chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard techniques. It is readily machinable, though maintaining sharp tools and liberal coolant use is crucial. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds yield the best results.
Stock Availability
Daxun Alloys maintains a robust inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet diverse needs.
Weight Reduction
Featuring low density and a high strength-to-weight ratio, CP 2 grade titanium tubes are ideal for applications requiring weight reduction without compromising strength. They are cold formable, exhibit excellent ductility, and can be welded using conventional TIG and MIG processes with inert gas shielding to prevent weld zone embrittlement.
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. At approximately 885°C [1625°F], they transform to a beta (body-centered cubic) structure. This transformation temperature can vary based on impurities or alloying additions. Alloying elements divide the equilibrium transformation temperature into two zones: the alpha transformation zone (all alpha) and the beta transformation zone (all beta), with both forms existing between these temperatures. 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 hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Throughout manufacturing, seamless tubes maintain continuous perimeters. The comprehensive manufacturing process includes: sponge titanium vacuum arc melting, blanking to obtain hollow blanks, cleaning, cutting, feeding, hot extrusion or oblique rolling and piercing, degreasing, drying, cutting, online annealing, straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.

The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, exhibits excellent weldability in both annealed and solution-treated conditions, with partial aging achieved through subsequent heat treatment.
To prevent contamination with oxygen, nitrogen, and hydrogen, precautions must be taken during welding. Fusion welding is best performed in an inert gas-filled chamber or with an inert gas tail shield protecting the molten metal and adjacent hot areas. Additionally, spot welding, seam welding, and flash welding can be executed without a protective atmosphere.
Special Considerations
The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, is susceptible to hydrogen contamination from improper pickling and the absorption of oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contaminations can reduce ductility and negatively impact notch sensitivity and formability.
