Adherence to top industry standards includes: 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 regarded as the industry standard, Grade 2 titanium tubes strike a perfect balance between moderate strength and reasonable ductility. They offer excellent corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. These tubes are indispensable in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard techniques. Machining is straightforward, provided sharp tools are maintained and coolant is liberally used. Similar to machining austenitic stainless steels, optimal results are achieved with deep, continuous cuts at slow feeds and speeds.

Weight Reduction
CP 2 grade titanium tubes are distinguished by their low density and high strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. They are cold-formable, possess good ductility, and can be welded using conventional TIG and MIG techniques, albeit with inert gas shielding to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes feature an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Upon reaching approximately 885°C (1625°F), they transition to a beta (body-centered cubic) structure. This transformation temperature is modifiable based on impurity levels or alloying additions, which also create two distinct temperature zones: an alpha transformation zone (all alpha below) and a beta transformation zone (all beta above). Between these temperatures, both 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 crafted from hollow blanks via hot extrusion or oblique rolling and piercing, followed by multiple cold rolling steps. The seamless tubes must retain continuous perimeters throughout all manufacturing stages. The entire process includes sponge titanium vacuum arc melting, ingot blanking into hollow blanks, cleaning, cutting, 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 a paragon of precision and reliability. Crafted from annealed flat-rolled steel plate or steel strip through the advanced automatic arc welding (TIG) process, each pipe undergoes a meticulous production journey. The main stages include: uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, secondary eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. To ensure maximum resilience, each welded pipe undergoes at least one stress relief heat treatment post forming and welding. Notably, Daxun's welding process is executed without any filler materials, underscoring the purity and integrity of the final product.
