Weight Reduction
CP 2 Grade Titanium Tubes boast a remarkable low density and an impressive strength-to-weight ratio, making them perfect for applications demanding weight reduction without compromising strength. These tubes are cold formable with excellent ductility and can be welded using conventional TIG and MIG processes, provided inert gas shielding is employed to prevent embrittlement of the weld zone.
Crystal Structure
At ambient temperatures, ASTM B338 Grade 2 Titanium Tube features 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. The precise transformation temperature can vary based on the type and quantity of impurities or alloying elements. Alloy additions create two distinct temperature zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which the alloy is all beta). Between these zones, both alpha and beta forms coexist. For Grade 2 Titanium, typical alpha and beta transformation temperatures are 890°C (1635°F) and 913°C (1675°F), respectively.
