ASME SB338 Grade2 Ti2 UNS R50400 Pure Titanium Seamless Tube
Description
ASME SB338 is the specific standard titled "Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers." While originally for heat exchangers, tubes made to this standard are used in many other critical applications.
Grade 2 is unalloyed titanium, known for its excellent corrosion resistance, good ductility, and moderate strength.
UNS R50400 as the Unified Numbering System code that uniquely identifies this specific material composition, corresponds directly to ASTM Grade 2 titanium.

Applications
Heat Exchangers & Condensers: The primary application in the standard's title. Used in chemical processing, power generation (especially offshore platforms), and desalination plants.
Chemical & Petrochemical Processing: For piping systems, reactors, and vessels handling corrosive chemicals.
Marine & Offshore: For seawater piping, ballast systems, and other components exposed to saltwater.
Aerospace: For hydraulic and pneumatic systems, and airframe components where weight savings are critical.
Medical & Pharmaceutical: For implants, surgical instruments, and processing equipment due to its biocompatibility.
