Crystal Structure
Intricate Crystal Structure of ASTM B338 Grade 2 Titanium Tube At room temperature, this titanium tube features an alpha (hexagonal close-packed) crystal structure. Upon heating to about 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. The transformation temperature can vary based on impurities or alloying elements, dividing the equilibrium transformation into distinct alpha and beta temperature zones. For Grade 2 titanium, typical alpha and beta transformation temperatures are 890°C (1635°F) and 913°C (1675°F), respectively. This dual-phase nature allows for a versatile range of applications and performance characteristics.

Weight Reduction
CP 2 grade titanium tubes are renowned for their low density and exceptional strength-to-weight ratio, making them ideal for applications requiring significant weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be seamlessly welded using conventional TIG and MIG processes. However, it is crucial to employ inert gas shielding to prevent weld zone embrittlement.
Crystal Structure
At ambient temperatures, 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 be adjusted depending on impurities or alloying additions. Alloy elements bifurcate the singular equilibrium transformation temperature into two distinct zones: the alpha transformation zone, culminating in an all-alpha alloy, and the beta transformation zone, resulting in an all-beta alloy. Between these temperatures, both alpha and beta phases coexist. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F).
