Daxun Alloy's pure titanium Grade 1 titanium tubes include:
Our seamless and welded titanium tubes boast exceptional ductility and cold formability, making them ideal for deep drawing applications. Grade 1 titanium tubes stand out for their superior general and seawater corrosion resistance and remarkable resilience against oxidizing, neutral, and slightly reducing media, including chlorides.
Titanium's unique combination of low density-about half that of nickel-based alloys-along with high strength, lightweight nature, and outstanding corrosion resistance, positions it as the material of choice for various challenging chemical environments. Our products adhere to rigorous standards, including 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)
This titanium tube is the most commonly utilized for industrial purposes, providing a perfect blend of moderate strength and excellent ductility. It delivers outstanding corrosion resistance in both highly oxidizing and slightly reducing environments, including chlorides. Its corrosion-resistant properties make it highly sought after in the chemical and offshore industries, as well as aircraft manufacturing, where both strength and formability are critical. Additional applications include heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping systems.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard techniques. It can be easily machined, though it's essential to keep tools sharp and use ample coolant. Similar to austenitic stainless steel machining, operations should involve deep and continuous cuts, with slow feeds and speeds for optimal results.
Stock Availability
Daxun Alloys maintains an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet diverse needs.
Weight Reduction
CP 2 grade titanium tubes offer a low-density and high strength-to-weight ratio, making them perfect for applications that require significant weight reduction without compromising strength. These tubes are cold formable and exhibit excellent ductility. They can be welded using conventional TIG and MIG methods, although inert gas shielding is necessary to avert weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes possess an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. At approximately 885°C (1625°F), they transform into a beta (body-centered cubic) structure. This transformation temperature can vary based on the impurity or alloying element content. Alloying elements split the single transformation temperature into two zones: the alpha transformation zone below which the alloy is entirely alpha, and the beta transformation zone above which the alloy is entirely beta. Between these temperatures, both alpha and beta forms coexist. Typical transformations for Grade 2 titanium occur at 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 processes, followed by several cold rolling stages. Throughout the manufacturing process, titanium seamless tubes maintain continuous perimeters. The production steps include: Vacuum arc melting of sponge titanium, blanking to obtain hollow blanks, cleaning, cutting, feeding, hot extrusion or oblique rolling and piercing, degreasing, drying, cutting, online annealing and straightening, pickling, repeated cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, 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 plate or steel strip utilizing the advanced automatic arc welding (TIG) process. The intricate production stages encompass: titanium plate uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing, 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 to ensure superior performance. At Daxun, we ensure high-quality welding by using specific filler materials during the process.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium Tube
Titanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400) stands as the pinnacle of titanium alloys. This duplex alpha+beta titanium alloy integrates aluminum as the alpha stabilizer and vanadium as the beta stabilizer, rendering it the most sought-after for high strength and versatility. Capable of enduring low temperatures around 800°F (427°C), ATI Ti-6Al-4V, Grade 5 alloy is optimal for annealing, solution treating, and aging. Its applications are vast, ranging from compressor blades, disks, and rings for jet engines, fuselage and space capsule components, pressure vessels, *** cases, to helicopter rotor hubs, fasteners, and critical forgings, all necessitating a high strength-to-weight ratio.
The alloy is initially melted using advanced techniques such as vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Post-initial melting, remelting is performed in one or two vacuum arc steps to ensure purity and consistency.

Machinability
Experience precision with the DAXUN Ti-6Al-4V Titanium Tube, Grade 5. Machining this tube is akin to working with austenitic stainless steels. Employ slow speeds, high feeds, and ensure robust tool rigidity. Utilize ample amounts of non-chlorinated cutting fluids to achieve impeccable results.
Weldability
The DAXUN Ti-6Al-4V Titanium Tube, Grade 5, excels in weldability. Whether in annealed or solution and partially aged conditions, this titanium tube responds well to welding. Aging can be successfully achieved during post-weld heat treatment.
To ensure superior weld integrity, precautions against contaminants such as oxygen, nitrogen, and hydrogen must be taken. Employ fusion welding within an inert gas-filled chamber or use an inert gas tail shield over molten metal and adjacent hot zones. Spot welding, seam welding, and flash welding are all feasible without requiring a protective atmosphere.
Special Considerations
Handle the DAXUN Ti-6Al-4V Titanium Tube, Grade 5, with care to prevent contamination. Improper pickling and the absorption of gases like hydrogen, oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing can lead to reduced ductility and compromised notch sensitivity and formability.
