ASME SB338 UNS R50400 Grade 2 titanium tube is a commercially pure titanium tube manufactured according to ASME SB338 specification for heat exchanger and industrial applications.
Grade 2 titanium is one of the most widely used commercially pure titanium grades due to its combination of corrosion resistance, low density and suitable mechanical properties.
These titanium tubes are commonly used in environments requiring resistance against seawater, chloride-containing media and chemical processing conditions.
The tubes can be supplied in seamless or welded forms with customized dimensions according to engineering requirements.
