Titanium Alloy Grade 9 Pipe – High-Strength Aerospace & Marine Grade Piping
XI AN LINHUI IMPORT AND EXPORT Co., LTD. manufactures precision-engineered Titanium Alloy Grade 9 pipe (Ti-3Al-2.5V, UNS R56320) that bridges the gap between commercially pure titanium and harder Grade 5 alloys. Our pipes contain 2.5-3.5% Aluminum and 2.0-3.0% Vanadium, delivering tensile strength of 620 MPa (90 ksi) and yield strength of 517 MPa—20-50% stronger than CP titanium.
With a density of just 4.48 g/cm³, you get exceptional strength-to-weight performance. Unlike Grade 5, our product maintains superior cold formability for bending and flaring during installation. We control thickness tolerance to ±0.05mm through precision cold rolling, ensuring stable forming performance for your critical applications.
Key Features & Benefits
Predominant Mechanical Performance
Our channels accomplish 90 ksi pliable quality in CWSR condition whereas holding fabulous ductility. You advantage from tall cycle weariness resistance perfect for vibration-prone environments.
Outstanding Erosion Immunity
Comparable to Review 2 in seawater and chloride arrangements. Your frameworks pick up virtual resistance to hole erosion and setting in marine applications.
Exceptional Weldability
Unlike Review 5, our combination welds effortlessly without filler metal. Weld zones keep up base metal erosion resistance, diminishing your support costs.

FAQ
Q: What's the difference between Grade 9 and Grade 2 titanium pipe?
A: Grade 9 offers 50% higher strength (620 MPa vs 410 MPa) while maintaining similar corrosion resistance. Choose Grade 9 when you need thinner walls for weight reduction.
Q: Can I cold-bend your Grade 9 pipes on-site?
A: Yes. Unlike Grade 5, our pipes tolerate cold bending to 3D minimum radius without cracking. Stress relief after forming is recommended for critical applications.
Q: Do you provide material certificates?
A: Every shipment includes EN 10204 3.1 certificates with heat number traceability. SGS or TÜV third-party testing available for aerospace projects.
Q: What's your minimum order quantity?
A: Stock items start at 100 kg. Custom sizes require 500 kg minimum for economical production runs.
Q: How do I verify authenticity?
A: Each pipe is laser-etched with heat number. We provide PMI (Positive Material Identification) reports matching certificate data.
