Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds.

Stock Availability

Daxun Alloys maintains an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes.

Weight Reduction

CP 2 grade titanium tubes feature low density and a high strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. They are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, with inert gas shielding necessary to prevent embrittlement of the weld zone.

Crystal Structure

At room temperature, ASTM B338 Grade 2 titanium tube possesses an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. At approximately 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can be adjusted based on impurities or alloying additions. Alloying elements also split the single equilibrium transformation temperature into two zones: the alpha transformation zone (below which the alloy remains alpha) and the beta transformation zone (above which the alloy is all beta). Between these temperatures, both alpha and beta forms coexist. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F), respectively.

Grade 2 Titanium Seamless Pipe Manufacturing Process

Daxun's ASTM B338 Grade 2 titanium seamless tubes are produced from hollow blanks using hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling operations. Throughout manufacturing, titanium seamless tubes should have continuous perimeters.
