Chemical Properties
Grade 9 Titanium Alloy Rod exhibits excellent resistance to corrosive environments:
- Acids and Alkalis: Strong resistance to dilute acids like sulfuric and hydrochloric; good resistance to alkalis; moderate resistance to concentrated acids.
- Seawater: Exceptional resistance to pitting and crevice corrosion in marine environments, ideal for Grade 9 titanium bar in marine applications.
- Environmental Limits: Performs best below 400°C in oxidizing conditions; may experience reduced corrosion resistance in highly reducing environments without surface treatment.
Things to Note (Limitations)
- High-Temperature Limits: Above 400°C, strength decreases; not recommended for prolonged exposure beyond 500°C.
- Reducing Acids: Limited resistance to hot concentrated reducing acids; protective coatings may be required in such conditions.
- Machining Challenges: Work-hardens during machining; requires low speeds, sharp tools, and proper cooling for Grade 9 titanium rod production.
- Cost: Higher cost compared to aluminum or stainless steel due to raw material and processing expenses.
Corrosion Data
| Environment | Corrosion Rate (mm/year) | Conditions | Notes |
|---|---|---|---|
| Stagnant Seawater | <0.001 | 25°C, 12 months exposure | No pitting observed |
| 5% Sulfuric Acid | 0.015 | 30°C, 3 months exposure | Good resistance in dilute solutions |
| 5% Hydrochloric Acid | 0.04 | 25°C, 1 month exposure | Moderate resistance |
| Atmospheric (Coastal, Humid) | <0.001 | 25°C, 12 months exposure | Excellent resistance |
| 5% Sodium Hydroxide (Alkaline) | <0.002 | 40°C, 3 months exposure | Excellent resistance |
| 5% Nitric Acid | <0.001 | 30°C, 3 months exposure | Superior resistance |
Welding and Manufacturing Tips
- Welding: Use TIG welding with pure argon shielding to prevent contamination; filler metals like ERTi-9 are recommended. Weld in a clean environment to avoid embrittlement.
- Forming: Excellent formability; can be cold or hot formed; hot forming should be done between 600°C and 800°C.
- Machining: Use low cutting speeds, high feed rates, and abundant coolant; suitable for producing Grade 9 titanium round bar but requires care to avoid galling.
- Heat Treatment: Annealing at 600–800°C followed by air cooling can relieve stresses and improve ductility.
