Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
This highly versatile titanium tube is the industry standard for countless applications, striking a perfect balance between moderate strength and excellent ductility. Renowned for its outstanding corrosion resistance, it performs superbly in both highly oxidizing and slightly reducing environments, including those containing chlorides. This makes it an ideal choice for chemical and offshore industries, as well as aircraft manufacturing where both strength and formability are crucial. Furthermore, it is extensively used in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard techniques. It is easily machinable, though it demands careful attention to tool sharpness and generous application of coolant. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds yield the best results.

Weight Reduction
With a low density and a high strength-to-weight ratio, CP 2 grade titanium tubes are perfect for applications demanding weight reduction without compromising strength. They are cold formable, exhibit good ductility, and are compatible with conventional TIG and MIG welding processes, though inert gas shielding is essential to prevent embrittlement in the weld zone.
Crystal Structure
At ambient temperature, ASTM B338 Grade 2 titanium tube boasts an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. On heating to around 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can vary based on the type and concentration of impurities or alloying elements. The introduction of alloying elements also divides the single equilibrium transformation temperature into two distinct zones: the alpha transformation zone (below which the alloy remains alpha) and the beta transformation zone (above which the alloy becomes beta). Between these temperatures, both alpha and beta phases coexist. For grade 2 titanium, typical alpha and beta transformation temperatures are 890°C (1635°F) and 913°C (1675°F), respectively.
