Key Features & Benefits
Superior Mechanical Performance
You gain exceptional strength-to-weight ratio with 89,900 psi tensile strength. The alloy's 20% elongation allows extensive cold working without cracking.
Outstanding Corrosion Resistance
Your equipment resists saltwater and mild acids effectively. Performance matches palladium-stabilized grades at lower cost.
Excellent Weldability
TIG welding maintains near-base-metal strength in heat-affected zones. No special filler metals required for joining.
Enhanced Formability
Cold forming capabilities exceed Grade 5. You can create complex shapes using standard press brake and hydroforming techniques.

Manufacturing Process
Raw Material Selection
We source sponge Titanium Grade 9 (Ti-3Al-2.5V) from certified mills. Heat number traceability ensures batch consistency from ingot to finished product.
Hot Forming & Extrusion
Billets undergo rough forging at 900°C and finishing at 843°C. Seamless tubes are pilger-rolled to eliminate weld seams and internal defects.
Cold Rolling & Drawing
Controlled cold working achieves thickness tolerance within ±0.05 mm. This process enhances surface finish and dimensional accuracy for precision applications.
Heat Treatment
Solution annealing at 593–760°C for 3 hours optimizes ductility. Stress relief at 316–649°C removes residual stresses from forming operations.
Final Surface Treatment
Options include acid pickling for oxide removal, mechanical polishing to Ra 0.4 µm, and bead blasting for textured finishes.
Quality Inspection
100% Non-Destructive Testing
Every tube undergoes ultrasonic and eddy current inspection. You receive zero-defect products with complete test reports.
Mechanical Testing
Tensile, hardness, and elongation tests on each production lot. Results must meet or exceed ASTM B338 minimum requirements.
Chemical Analysis
Spectrometric analysis verifies alloy composition. Interstitial element control ensures oxygen ≤0.15% for consistent performance.
Dimensional Verification
CMM and optical measurement systems check OD, wall thickness, and straightness. Certificates include actual measured values.
Traceability Documentation
You receive EN 10204 3.1 material test certificates. Heat numbers are laser-etched on each piece for full supply chain transparency.
