Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Grade 2 Titanium Tubes are a top choice for industrial applications due to their outstanding balance of moderate strength and ductility. Renowned for their exceptional corrosion resistance in both highly oxidizing and slightly reducing environments, including chlorides, these tubes are indispensable in chemical and offshore industries, aircraft manufacturing, and heat exchanger systems. Their robust performance extends to hypochlorite systems, fire water systems, ballast water systems, CPI equipment, and various industrial and aerospace components.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard techniques. While it can be easily machined, it requires sharp tools and abundant coolant. Similar to austenitic stainless steels, machining should involve deep, continuous cuts at slow feeds and speeds to ensure optimal performance.

Weight Reduction
CP 2 Grade Titanium Tubes are engineered for applications demanding weight reduction without compromising strength. Their low density and high strength-to-weight ratio make them ideal for such needs. These tubes are cold-formable, exhibit excellent ductility, and are weldable using conventional TIG and MIG processes, provided inert gas shielding is applied to prevent weld zone embrittlement.
Crystal Structure
At room temperature, 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 transformation temperature can vary with impurities or alloying elements, which also create two distinct temperature zones: the alpha transformation zone below which the alloy is entirely alpha, and the beta transformation zone above which it is entirely beta. Typical temperatures for these transformations in 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 crafted from hollow blanks via hot extrusion or oblique rolling and piercing, followed by multiple cold rolling stages. These tubes maintain continuous perimeters throughout manufacturing. The process encompasses: sponge titanium vacuum arc melting, ingot blanking to create hollow blanks, cleaning, cutting, and feeding; followed by hot extrusion, or oblique rolling and piercing, degreasing, drying, cutting, online annealing, and straightening; plus pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 Titanium Welded Pipes are produced from annealed flat-rolled steel plate or strip using an automated TIG welding process.

Weight Reduction
CP 2 grade titanium tubes are renowned for their low density and high strength-to-weight ratio, ideal for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit excellent ductility, and can be welded using conventional TIG and MIG processes. It is crucial to use inert gas shielding to prevent embrittlement in the weld zone, ensuring superior performance and longevity.
Crystal Structure
At room temperature, our ASTM B338 Grade 2 titanium tube flaunts an alpha (hexagonal close-packed) crystal structure, 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. The transformation temperature is influenced by the presence and quantity of impurities or alloying elements, which can also split the single equilibrium transformation temperature into two distinct zones: the alpha transformation zone and the beta transformation zone. In these zones, the alloy exhibits different structural forms, with typical alpha and beta transformation temperatures for Grade 2 titanium being 890°C (1635°F) and 913°C (1675°F), respectively.
