Weight Reduction
With its low density and high strength-to-weight ratio, CP 2 grade titanium tubes are the ideal solution for applications demanding significant weight reductions without compromising strength. These tubes are easily cold formable, exhibit good ductility, and are compatible with conventional TIG and MIG welding processes. However, inert gas shielding is crucial to prevent embrittlement during welding.
Crystal Structure
At ambient conditions, ASTM B338 Grade 2 titanium tubes possess an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Upon reaching approximately 885°C (1625°F), the structure transforms into a beta (body-centered cubic) form. This transformation temperature can vary based on impurity levels or alloying additives. Alloying elements further split the equilibrium transformation temperature into two distinct zones: the alpha transformation zone (entirely alpha) and the beta transformation zone (entirely beta), with both forms coexisting in between. For Grade 2 titanium, typical alpha and beta transformation temperatures are 890°C (1635°F) and 913°C (1675°F), respectively.

Crystal Structure
At ambient temperature, the ASTM B338 Grade 2 titanium tube 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 transition temperature is influenced by the type and amount of impurities or alloying elements. Alloying elements further delineate the equilibrium transformation into alpha and beta zones. For Grade 2 titanium, typical alpha and beta transformation temperatures are 890°C (1635°F) and 913°C (1675°F), respectively.
