Titanium and its alloys are high-performance metals capable of withstanding extremely high temperatures. Specification ASTM B338 covers approximately 28 grades of titanium alloys. The titanium tubing defined by this specification is widely used in heat exchangers, surface condensers, and evaporators.
Key Applications: High-temperature environments where longevity and excellent performance are critical. Components are available in both seamless and welded constructions.
Seamless tubes are produced from hollow billets through cold reducing or cold drawing processes. Welded construction utilizes an automatic arc weld process, followed by adequate cold working to transform the cast weld microstructure into a conventional equiaxed microstructure via heat treatment.
