Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
This is the most frequently employed titanium tube for industrial applications, offering an outstanding balance of moderate strength and reasonable ductility. It delivers excellent corrosion resistance in both highly oxidizing and slightly reducing environments, including chlorides. It provides impressive corrosion protection in the chemical and offshore industries, as well as in aircraft manufacturing, where strength and ease of forming are paramount. Additionally, it's used in heat exchangers, hypochlorite systems, firewater systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping.
Fabrication
Titanium Grade 2 responds exceptionally well to cold forming using conventional methods. It can be easily machined, but it is crucial to maintain sharp tools and use plenty of coolant. Similar to machining austenitic stainless steels, cuts should remain deep and continuous, with slow feed rates and speeds to achieve optimal results.

Weight Reduction
CP 2 grade titanium tubes boast low density and a high strength-to-weight ratio, making them ideal for applications requiring weight reduction without compromising overall strength. They are cold-formable, exhibit good ductility, and can be welded using standard TIG and MIG processes, although inert gas shielding is necessary to prevent embrittlement in the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube features an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. At approximately 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can be altered depending on the type and amount of impurities or alloying additions. The introduction of alloying elements divides the single temperature of the equilibrium transformation into two zones: the alpha transformation zone, below which the alloy is entirely alpha, and the beta transformation zone, above which the alloy is entirely beta. Between these two temperatures, both alpha and beta forms coexist. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F), respectively.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are crafted from hollow blanks through hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Titanium seamless tubes must maintain continuous perimeters throughout the manufacturing operation.

Crystal Structure
At ambient temperatures, the ASTM B338 Grade 2 titanium tubes from Jiangsu Daxun Alloy Co., Ltd. exhibit an alpha (hexagonal close-packed) crystal structure, consistent with commercially pure titanium grades 1 and 3. When heated to about 885°C (1625°F), they transform into a beta (body-centered cubic) structure. This transformation temperature can be altered by the presence and quantity of impurities or alloying elements. Such additions create distinct temperature zones: the alpha transformation zone (below which the alloy is completely alpha) and the beta transformation zone (above which the alloy is fully beta). Between these zones, both alpha and beta phases coexist. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F).
