Daxun Alloy's Pure Titanium Grade 1 Tubes Include:
Choose from our seamless or welded titanium tubes, each offering outstanding ductility and cold formability-perfect for deep drawing. Grade 1 titanium tubes are celebrated for their exceptional general and seawater corrosion resistance. They excel against oxidizing, neutral, and slightly reducing media (including chlorides), making them a versatile and reliable choice.
Titanium's intrinsic low density (approximately half that of nickel-based alloys), combined with its high strength, light weight, and exceptional corrosion resistance, make it the material of choice for challenging chemical environments. Compliance standards include: 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)
Renowned as the go-to titanium tube for industrial applications, Grade 2 titanium offers an ideal balance of moderate strength and excellent ductility. Its superior corrosion resistance shines in both highly oxidizing and slightly reducing environments (including chlorides). This makes it indispensable for the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, and industrial and aerospace components, including CPI equipment and pipes.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard methods. It machines readily with sharp tools and ample coolant. As with austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended for optimal results.
Stock Availability
Daxun Alloy maintains an extensive stock of CP Grade 2 Titanium Seamless and Welded Pipes in a range of sizes to meet diverse requirements.
Weight Reduction
With their low density and high strength-to-weight ratio, CP Grade 2 titanium tubes are ideal for applications demanding weight reduction without compromising strength. They offer excellent cold formability and 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 exhibits an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium Grades 1 and 3. Around 885°C (1625°F), it transforms into a beta (body-centered cubic) structure. The exact transformation temperature can vary with the type and amount of impurities or alloying elements. Alloy additions can also split the transformation into two temperature zones: the alpha zone (below which the alloy is all alpha) and the beta zone (above which the alloy is all beta). Between these temperatures, alpha and beta forms coexist. Typical transformation temperatures for Grade 2 titanium are 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 meticulously crafted from hollow blanks through hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Throughout the manufacturing operation, the seamless tubes maintain continuous perimeters. The comprehensive production process includes: sponge titanium vacuum arc melting, ingot blanking to create 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
Daxun's ASTM B338 Grade 2 Titanium Welded Pipe is meticulously crafted from annealed flat-rolled steel plate or steel strip using an advanced automatic arc welding (TIG) process. The comprehensive production sequence includes: titanium plate uncoiling, precision shearing, seamless butt welding, thorough cleaning, precise pipe forming, TIG welding, advanced eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, secondary eddy current testing, accurate caliper marking, cutting, ultrasonic testing, rigorous hydrostatic testing, meticulous final inspection, and secure packaging. Each welded pipe undergoes at least one stress relief heat treatment post-forming and welding. Notably, Daxun ensures the use of high-quality filler materials during the welding process.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium TubeTitanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400), stands as the premier choice among titanium alloys. This duplex alpha+beta titanium alloy incorporates aluminum as the alpha stabilizer and vanadium as the beta stabilizer, making it exceptionally high-strength and versatile, suitable for low-temperature applications around 800°F (427°C). Known for its remarkable strength, ATI Ti-6Al-4V, Grade 5 alloy is ideal for annealing, solution treating, and aging. It is extensively used in critical applications such as jet engine compressor blades, disks, and rings; fuselage and space capsule components; pressure vessels; *** casings; helicopter rotor hubs; fasteners; and other high strength-to-weight ratio forgings.
The alloy undergoes initial melting using advanced methods like vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Subsequent remelting is conducted through one or two steps of vacuum arc processing.

Optimum Properties Optimal properties are achieved in small cross-sections with rapid quenching in the solution-treated and aged condition. Larger cross-sections or delayed quenching may result in less than optimal attributes.
HardnessTypical hardness in the annealed condition is Rockwell C 30-34, while in the solution-treated and aged condition, it is approximately Rockwell C 35-39.
Forgeability/Formability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is expertly forged at an elevated temperature of 1,750°F (954°C), culminating in a final forging temperature of 1,450°F (788°C). For superior performance, a reduction of at least 35% is highly recommended to achieve the best results.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube poses challenges in forming at room temperature, even when annealed. However, rigorous forming operations such as bending or stretching can be executed on the annealed material at temperatures up to 1,200°F (649°C) without impacting its mechanical properties. For hot sizing or forming at temperatures ranging from 1,000 to 1,200°F (538 to 649°C), creep forming is an effective technique.
Machinability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube showcases excellent machinability when using methods suited for austenitic stainless steels. Optimal results are achieved with slow speeds, high feeds, robust tool rigidity, and the application of copious non-chlorinated cutting fluids.
Weldability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube exhibits remarkable weldability, whether in the annealed condition or after solution and partial aging. Post-weld heat treatment is essential for aging.
During post-weld heat treatment, DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube necessitates precautions to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber or with an inert gas tail shield protecting the molten metal and adjacent hot zones. Additionally, spot welding, seam welding, and flash welding can all be executed without a protective atmosphere.
Special Considerations DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is susceptible to contamination from hydrogen during improper pickling, as well as from the absorption of oxygen, nitrogen, and carbon during forging, heat treating, brazing, and other processes. Such contamination can compromise ductility, increase notch sensitivity, and affect formability.
