Chemical Composition
ASTM B338 Titanium Tube is available in multiple grades with controlled alloy composition:
Gr1 / Gr2 / Gr3: High purity titanium for corrosion resistance applications
Gr5 (Ti-6Al-4V): High strength aerospace-grade alloy
Gr7: Palladium-enhanced corrosion resistance
Gr9: Balanced strength and formability (aerospace hydraulic systems)
Gr12: Improved resistance in aggressive chemical environments
Gr23: Extra low interstitial medical-grade titanium
Each grade is strictly controlled for:
Oxygen, Nitrogen, Carbon, Hydrogen, Iron content
Alloying elements (Al, V, Pd, Mo, Ni depending on grade)
Titanium balance purity for performance stability
Mechanical Properties
ASTM B338 Titanium Tube is engineered for structural reliability under demanding conditions:
Gr1: 240 MPa tensile strength / high ductility
Gr2: 345 MPa tensile / 275 MPa yield strength
Gr5: Up to 895 MPa tensile strength (high-strength alloy)
Gr9: 620 MPa tensile strength (aerospace hydraulic use)
Elongation: 10%–24% depending on grade
Reduction of area: 25%–30%
These properties ensure stable performance in pressure systems, structural applications, and corrosive environments.
