Daxun Alloy proudly offers pure titanium Grade 1 tubes that include:
Our seamless and welded titanium tubes boast excellent ductility and cold formability, making them perfect for deep drawing applications. Renowned for their good general and seawater corrosion resistance, these tubes also exhibit outstanding resistance to oxidizing, neutral, and slightly reducing media, including chlorides.
Titanium's low density, approximately half that of nickel-based alloys, coupled with high strength, light weight, and excellent corrosion resistance, makes it ideal for harsh chemical environments. Adhering to the highest standards, our products comply with 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 industry standard for industrial applications, offering a superb balance of moderate strength and reasonable ductility. These tubes provide exceptional corrosion resistance in both 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, CPI equipment, and industrial and aerospace components.
Fabrication
Titanium Grade 2 responds exceptionally well to cold forming using standard methods. It can be easily machined, although special care must be taken to maintain sharp tools and the liberal use of coolant. Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds.

Daxun Alloys maintains a robust inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet your needs.
Weight Reduction
CP 2 grade titanium tubes, with their low density and high strength-to-weight ratio, 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, provided inert gas shielding is used to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes feature an alpha (hexagonal close-packed) crystal structure, akin 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 depending on impurities or alloying additions, which can also divide the single equilibrium transformation temperature into two zones: the alpha transformation zone and the beta transformation zone. Between these temperatures, both alpha and beta forms co-exist. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F).
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are meticulously crafted from hollow blanks via hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Ensuring continuous perimeters at all stages, the production process includes sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, cleaning, cutting and feeding, hot extrusion or oblique rolling and piercing, degreasing, drying, cutting, online annealing and straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Experience the pinnacle of quality with Daxun's ASTM B338 Grade 2 titanium welded pipe. Crafted meticulously from annealed flat-rolled steel plate or steel strips through an advanced automatic arc welding (TIG) process, our production line is a testament to precision and durability. The pivotal production stages encompass: titanium plate uncoiling, shearing, butt welding, comprehensive cleaning, pipe forming, precise TIG welding, eddy current testing, pre-sizing, annealing, precision reducing, sizing, straightening, caliper marking, cutting, ultrasonic testing, hydrostatic testing, and thorough final inspection before packaging. To ensure impeccable quality, all welded pipes undergo at least one stress relief heat treatment post-forming and welding, with Daxun adhering to the strictest standards by incorporating filler materials during the welding process.

Weldability Effortless welding is a hallmark of the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, whether in annealed or solution and partially aged conditions, with aging.
Post-weld heat treatment completes the process. To preserve integrity, avoid contamination with oxygen, nitrogen, and hydrogen. Utilize fusion welding within an inert gas-filled chamber or apply an inert gas tail shield to protect the molten metal and adjacent hot zones. Versatile welding options include spot welding, seam welding, and flash welding, all achievable without a protective atmosphere.
Special Considerations Care must be taken with the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube to avoid contamination. Improper pickling and absorption of oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing can introduce hydrogen, which may compromise ductility and adversely affect notch sensitivity and formability.
