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)
This popular industrial-grade titanium tube strikes a perfect balance between moderate strength and reasonable ductility. Known for its outstanding corrosion resistance in both highly oxidizing and slightly reducing conditions (chlorides included), it excels in chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite and fire water systems, ballast water systems, CPI equipment, and industrial and aerospace components.
Fabrication
Titanium Grade 2 is highly amenable to cold forming using standard techniques. It machines well, but maintaining sharp tools and ample coolant is crucial. Similar to machining austenitic stainless steels, it requires deep, continuous cuts at slow feeds and speeds.
Stock Availability
Daxun Alloys offers an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet diverse needs.
Weight Reduction
With a low density and high strength-to-weight ratio, CP 2 grade 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 methods, provided inert gas shielding is used to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube boasts an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can shift based on impurities or alloying elements, which also bifurcate the equilibrium transformation temperature into two zones: alpha below and beta above. Between these temperatures, both alpha and beta forms exist. 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 crafted from hollow blanks via hot extrusion or oblique rolling and piercing, followed by multiple cold rolling stages. Throughout the manufacturing process, these seamless tubes maintain continuous perimeters. The comprehensive manufacturing involves sponge titanium vacuum arc melting, ingot blanking, 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 utilizing an advanced automatic arc welding (TIG) process. Our comprehensive production procedure includes: titanium plate uncoiling, precise shearing, seamless butt welding, thorough cleaning, precision pipe forming, flawless TIG welding, rigorous eddy current testing, meticulous pre-sizing, optimal annealing, precision reducing and sizing, impeccable straightening, additional eddy current testing, precise caliper marking, accurate cutting, comprehensive ultrasonic testing, stringent hydrostatic testing, final thorough inspection, and secure packaging. Each welded pipe undergoes a mandatory stress relief heat treatment post forming and welding. Daxun ensures the highest quality by avoiding any filler materials during the welding process.

To ensure exceptional weld quality, it's crucial to avoid contamination with oxygen, nitrogen, and hydrogen. Fusion welding should be performed within an inert gas-filled chamber or with the use of 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 conducted without a protective atmosphere, maintaining the tube's integrity.
Special Considerations
While working with the DAXUN Ti-6Al-4V Titanium Tube, Grade 5, it's vital to be aware of potential contamination risks. Improper pickling or the absorption of oxygen, nitrogen, and carbon during forging, heat treatment, and brazing can introduce hydrogen contamination. Such contamination may negatively impact ductility, notch sensitivity, and formability. Taking appropriate precautions will ensure the tube's exceptional performance remains uncompromised.
