Titanium Alloy Grade 9 – High-Strength Lightweight Tubing & Sheet Solutions
XI AN LINHUI IMPORT AND EXPORT Co., LTD. supplies premium Titanium Alloy Grade 9 (Ti-3Al-2.5V / UNS R56320) conforming to ASTM B861, B862, B338, B265, and B348 standards. Our annealed-condition products bridge the gap between commercially pure titanium and Grade 5, delivering 20-50% higher tensile strength than CP grades while maintaining superior cold formability.
Available in pipes/tubes (OD 3.2–219mm, WT 0.5–10mm), sheets/plates (Thk 0.5–30mm), and bars (Φ6–150mm), our factory-direct supply ensures thickness tolerance within ±0.05mm and 100% NDT inspection for zero-defect quality control across aerospace hydraulic systems and marine applications.
Key Features & Benefits
Superior Strength-to-Weight Ratio
Grade 9 achieves tensile strength of 620–860 MPa while maintaining a density of just 4.48 g/cm³. You get 40% weight reduction versus steel without compromising structural integrity.
Excellent Cold Workability
Unlike high-strength Grade 5, this alloy allows seamless tube drawing and complex bending operations. Your production benefits from reduced processing costs and shorter lead times.
Marine-Grade Corrosion Resistance
Proven immunity to crevice corrosion in seawater and chloride environments. You eliminate maintenance downtime in offshore and subsea installations.

Manufacturing Process
Step 1: Controlled Forging
Ingots undergo multi-stage forging at 850-950°C to refine grain structure and eliminate internal voids.
Step 2: Cold Rolling/Drawing
Pipes achieve ±0.05mm dimensional accuracy through precision cold-drawing equipment. Sheets undergo controlled rolling for uniform thickness distribution.
Step 3: Annealing Treatment
Stress-relief annealing at 650-750°C for 2-4 hours ensures consistent mechanical properties and removes residual stresses.
Step 4: Surface Treatment
Acid pickling removes scale while preserving corrosion resistance. Optional electropolishing achieves Ra 0.4μm surface finish for hygienic applications.

FAQ
Q: What's the contrast between tempered and CWSR condition?
A: Toughened offers superior formability for advance handling. CWSR (Cold Worked Stretch Diminished) gives 15-20% higher quality for final-use applications.
Q: Can you give little amounts for testing?
A: Yes. We bolster test orders from 10kg with the same quality benchmarks as bulk production.
Q: How does Review 9 compare to Review 5 in welding?
A: Review 9 welds more effectively due to lower aluminum substance. You do not require preheating for thicknesses beneath 6mm, decreasing creation complexity.
Q: Do you offer custom cutting services?
A: Completely. We give cutting, twisting, and machining per your drawings. Share determinations for a point by point quote.
Q: What's your normal lead time for custom orders?
A: Standard generation completes in 15-25 days. Surge orders accessible with 10-15 day turnaround upon fabric accessibility affirmation.
