Daxun Alloy's Pure Titanium Grade 1 Titanium Tubes include:
Seamless Titanium Tubes and Welded Titanium Tubes, renowned for their exceptional ductility and cold formability, ideal for deep drawing applications. Grade 1 Titanium Tubes excel in general and seawater corrosion resistance, providing outstanding protection against oxidizing, neutral, and mildly reducing media, including chlorides.
Titanium's low density (approximately half that of nickel-based alloys), combined with its high strength, light weight, and superior corrosion resistance, makes it the material of choice for demanding chemical environments. Execution standards include: 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 Tube is widely favored for industrial applications, offering an outstanding balance of moderate strength and commendable ductility. It provides excellent corrosion resistance in both highly oxidizing and mildly reducing environments, including chlorides. This grade is extensively used in chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping solutions.
Fabrication
Titanium Grade 2 is highly responsive to cold forming through standard techniques. It is readily machinable, though it is crucial to maintain sharp tools and use coolant generously. Similar to machining austenitic stainless steels, the approach should involve deep, continuous cuts with slow feeding speeds.

Weight Reduction
CP 2 grade titanium tubes boast a low density and an impressive strength-to-weight ratio, making them perfect for applications requiring weight reduction without compromising on strength. They are cold formable, exhibit excellent ductility, and can be welded using conventional TIG and MIG processes, provided inert gas shielding to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 Titanium Tube exhibits an alpha (hexagonal close-packed) crystal structure, similar 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 elements, dividing the single equilibrium transformation temperature into an alpha zone (below which the alloy remains alpha) and a beta zone (above which the alloy remains beta). Between these temperatures, both alpha and beta forms coexist. For Grade 2 Titanium, typical alpha and beta transformation temperatures are 890°C (1635°F) and 913°C (1675°F), respectively.

Titanium Alloy - (UNS R56400)
Introduction
Introducing the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400) - the epitome of excellence in titanium alloys. This duplex alpha+beta titanium alloy employs aluminum as the alpha stabilizer and vanadium as the beta stabilizer, creating a high-strength alloy capable of performing optimally at temperatures as low as 800°F (427°C). Renowned for its versatility, the ATI Ti-6Al-4V, Grade 5 alloy is perfect for annealing, solution treating, and aging. Its applications span across compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings, all benefiting from its high strength-to-weight ratio.
Our alloy's initial melting is performed using cutting-edge methods such as vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). We ensure superior purity and quality by achieving remelting in one or two vacuum arc steps.

Precautions are imperative to prevent contamination by oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with an inert gas tail shield to protect the molten metal and adjacent hot zones. Methods such as spot welding, seam welding, and flash welding can be executed without a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube requires careful handling to avoid hydrogen contamination from improper pickling processes and the absorption of oxygen, nitrogen, and carbon during forging, heat treating, brazing, and other operations. Such contamination can diminish ductility, impair notch sensitivity, and reduce formability.
