Adhering to rigorous standards such as ASTM B338, ASTM B265, ASME SB265, ASTM F67, ISO 5832-2, 3.7025, and UNS R50250, our titanium products ensure top-tier performance.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Among the most prevalent in industrial applications, the Grade 2 Titanium Tube strikes an impeccable balance of moderate strength and commendable ductility. Its superb corrosion resistance excels in both highly oxidizing and slightly reducing conditions, including chlorides. This tube is a reliable choice for the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping needs.
Fabrication
Titanium Grade 2 is highly amenable to cold forming using standard methods. While it can be easily machined, maintaining sharp tools and liberal coolant usage is crucial. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds yield the best results.
Stock Availability
At Daxun Alloys, we maintain a comprehensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in an assortment of 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 demanding weight reduction without compromising strength. These tubes are cold formable, exhibit excellent ductility, and are weldable using conventional TIG and MIG processes, necessitating inert gas shielding to prevent embrittlement of the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium exhibits an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium Grades 1 and 3. Upon reaching 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, which further segment the equilibrium transformation into alpha and beta zones. The alpha transformation zone is below 890°C (1635°F), while the beta transformation zone is above 913°C (1675°F), with both forms coexisting between these temperatures.
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. Ensuring continuous perimeters throughout all manufacturing operations, the 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 crafted from annealed flat-rolled steel plates or steel strips using the automated arc welding (TIG) process. The comprehensive production process includes: 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. To ensure utmost quality and strength, welded pipes undergo at least one stress relief heat treatment after forming and welding. Significantly, Daxun ensures no filler materials are used during the welding process, preserving the integrity and purity of the titanium.
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 most sought-after titanium alloy, renowned for its duplex alpha+beta composition. Utilizing aluminum as the alpha stabilizer and vanadium as the beta stabilizer, this high-strength alloy excels even at lower temperatures of approximately 800°F (427°C). ATI Ti-6Al-4V, Grade 5 alloy is indispensable in processes such as annealing, solution treating, and aging. Its applications span across critical aerospace and industrial components, including compressor blades, disks, and rings for jet engines; fuselage and space capsule parts; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and high-strength-to-weight ratio forgings.
The alloy undergoes initial melting using advanced techniques such as vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Remelting is typically achieved through one or two vacuum arc steps, ensuring superior material quality.

Take essential precautions to prevent contamination by oxygen, nitrogen, and hydrogen. Execute fusion welding in an inert gas-filled chamber or utilize an inert gas tail shield over molten zones. Processes like spot welding, seam welding, and flash welding can be conducted without a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube: Be wary of hydrogen contamination from improper pickling and the absorption of oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination may reduce ductility, impair notch sensitivity, and affect formability. Ensure meticulous handling to maintain the integrity and performance of our titanium tubes.
