Daxun Alloy's Pure Titanium Grade 1 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 are renowned for their superior general and seawater corrosion resistance, as well as excellent resistance to oxidizing, neutral, and slightly reducing media, including chlorides.
Titanium's low density-roughly half that of nickel-based alloys-combined with high strength, light weight, and outstanding corrosion resistance, makes it an unparalleled choice for demanding chemical environments. Our titanium tubes adhere to the following 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)
Widely favored for industrial applications, Grade 2 titanium tubes strike a perfect balance between moderate strength and excellent ductility. These tubes offer robust corrosion resistance in both highly oxidizing and slightly reducing environments, 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 more.
Fabrication
Grade 2 titanium is highly amenable to cold forming using standard techniques. It can be machined with ease, provided that sharp tools and liberal use of coolant are maintained. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Daxun Alloys offers an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet diverse requirements.
Weight Reduction
CP 2 grade titanium tubes are characterized by their low density and high strength-to-weight ratio, making them ideal for applications requiring weight reduction without compromising strength. These tubes are cold-formable, possess good ductility, and can be welded using conventional TIG and MIG processes, with inert gas shielding to prevent weld zone embrittlement.
Crystal Structure
At ambient temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), this structure transitions to a beta (body-centered cubic) form. Alloying elements can modify this transformation temperature, resulting in alpha and beta transformation zones. For Grade 2 titanium, the typical alpha transformation temperature is 890°C (1635°F) and the beta transformation temperature is 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. The seamless manufacturing 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, 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 plates or steel strips using an advanced automatic arc welding (TIG) process. The comprehensive production process involves: titanium plate uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Each welded pipe undergoes essential stress relief heat treatment post-forming and welding. Daxun ensures precision by incorporating filler materials during the welding 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 premier choice among titanium alloys. This duplex alpha+beta titanium alloy utilizes aluminum as the alpha stabilizer and vanadium as the beta stabilizer, delivering remarkable strength suitable for temperatures as low as 800°F (427°C). The ATI Ti-6Al-4V, Grade 5 alloy undergoes annealing, solution treating, and aging, making it ideal for high-performance applications such as compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings demanding a high strength-to-weight ratio.
This alloy undergoes initial melting through processes like vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM), followed by one or two vacuum arc remelting steps.

Additionally, hot sizing or forming using creep forming at temperatures ranging from 1,000 to 1,200°F (538 to 649°C) ensures outstanding performance and reliability.
Machinability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5: Precision Machining. This high-grade titanium tube can be expertly machined using the techniques designed for austenitic stainless steels. By employing slow speeds, high feeds, rigorous tool rigidity, and ample non-chlorinated cutting fluids, you achieve precision and exceptional results every time.
Weldability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5: Superior Weldability. This tube is readily weldable in both its annealed and solution-partially aged conditions. Post-weld heat treatment completes the process with aging.
During the welding process, it is crucial to avoid contamination with oxygen, nitrogen, and hydrogen to maintain the integrity of the titanium. Fusion welding should be performed in an inert gas-filled chamber or using an inert gas tail shield over the molten metal and adjacent hot zones. Spot welding, seam welding, and flash welding can be executed successfully without the need for a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5: Handling with Care. To preserve the exceptional properties of this titanium tube, it is essential to prevent contamination from hydrogen during improper pickling, and from oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can reduce ductility, affecting notch sensitivity and formability. Adhering to proper handling procedures ensures the tube's superior performance and longevity.
