Weight Reduction

CP 2 Grade Titanium Tubes are designed to deliver an outstanding strength-to-weight ratio, ideal for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and are easily weldable using conventional TIG and MIG processes, although inert gas shielding is imperative to prevent weld zone embrittlement.

Crystal Structure

At ambient temperatures, ASTM B338 Grade 2 Titanium Tube features an alpha (hexagonal close-packed) crystal structure, mirroring the properties of commercially pure Titanium Grades 1 and 3. Upon reaching approximately 885°C [1625°F], it transitions to a beta (body-centered cubic) structure. This transformation temperature can be adjusted with specific impurities or alloying additions. Alloying elements alter the single temperature of equilibrium transformation into two zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which the alloy is all beta). In the intermediate temperatures, both alpha and beta forms coexist. Typical transformation temperatures for Grade 2 Titanium are 890°C (1635°F) for alpha and 913°C (1675°F) for beta.

These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, with careful inert gas shielding to prevent embrittlement in the weld zone.

Crystal Structure

The ASTM B338 Grade 2 titanium tube presents an alpha (hexagonal close-packed) crystal structure at room temperature, akin to commercially pure titanium grades 1 and 3. Upon reaching approximately 885°C (1625°F), it transforms into a beta (body-centered cubic) structure. This transformation temperature may vary with different impurities or alloying additions. The inclusion of alloying elements diversifies the equilibrium transformation into two temperature zones: the alpha transformation zone (all alpha alloy) and the beta transformation zone (all beta alloy). Between these temperatures, both alpha and beta forms coexist, with typical transformation temperatures for Grade 2 titanium being 890°C (1635°F) and 913°C (1675°F), respectively.
