Titanium Grade 7 (Ti-0.15Pd) Sheet, Plate, Strip and Coil to ASTM B265
Dinesh Tube India supplies and exports titanium Grade 7 sheets, plates, strip and coil from Mumbai to chemical, chlor-alkali, hydrometallurgy and acid-plant fabricators in India and abroad. Grade 7 (UNS R52400, Werkstoff 3.7235) is commercially pure titanium with 0.12–0.25% palladium, supplied to ASTM B265 / ASME SB265 with EN 10204 3.1 mill test certificates.
The small palladium addition makes Grade 7 the most corrosion-resistant of the common titanium grades. It handles dilute hydrochloric and sulphuric acid and hot chloride crevices where Grade 2 corrodes, while keeping Grade 2's strength and easy fabrication. For other grades, see our titanium sheets and plates page.
Titanium Grade 7 vs Grade 2 vs Grade 12
| Point | Grade 2 | Grade 7 | Grade 12 |
|---|---|---|---|
| Alloying | None (CP) | Pd 0.12–0.25 | Mo 0.2–0.4, Ni 0.6–0.9 |
| Min. tensile / yield | 345 / 275 MPa | 345 / 275 MPa | 483 / 345 MPa |
| Dilute reducing acids (HCl, H2SO4) | Poor to fair | Best | Good |
| Crevice corrosion in hot chlorides | Fair | Excellent | Excellent |
| Cost | Lowest | Highest (palladium) | Moderate |
| Choose it for | Seawater and general chloride service | Reducing acids and the most severe crevice service | Hot brines at lower cost than Grade 7 |
Grade 16 (Ti-0.05Pd) and Grade 26 (Ti-0.1Ru) are lower-cost alternatives with similar but slightly lower corrosion resistance. Ask if your specification allows them.

Physical Properties (approx.)
Why Titanium Grade 7 in Reducing Acids?
Like all titanium, Grade 7 is not suitable for hydrofluoric acid, fluorides or dry chlorine gas, and is not intended for hot, concentrated reducing acids, where zirconium or tantalum may be needed. See the full guide on our titanium sheets and plates page.
Grade 7 Sheet Weight Calculation
Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 4.51
For example, a 2000 × 1000 × 3 mm Grade 7 sheet weighs about 2 × 1 × 3 × 4.51 = 27 kg.

Titanium Grade 7 Sheet & Plate Applications
Titanium Grade 7 Sheets & Plates: FAQs
What is titanium Grade 7?
Titanium Grade 7 (UNS R52400, Werkstoff 3.7235) is commercially pure titanium with 0.12–0.25% palladium. It is supplied as sheet, plate, strip and coil to ASTM B265 / ASME SB265 and has the best corrosion resistance of the common titanium grades.
What is the chemical composition of titanium Grade 7?
Per ASTM B265: palladium 0.12–0.25%, iron 0.30% max, oxygen 0.25% max, carbon 0.08% max, nitrogen 0.03% max, hydrogen 0.015% max, balance titanium.
What is the difference between titanium Grade 7 and Grade 2?
They have the same base chemistry and strength (345 MPa minimum tensile). Grade 7 adds palladium, which greatly improves resistance to dilute reducing acids such as hydrochloric and sulphuric acid, and to crevice corrosion in hot chlorides.
Should I choose Grade 7 or Grade 12?
Grade 7 is better in reducing acids and the most severe crevice conditions. Grade 12 is stronger and cheaper and is often enough for hot brines. If cost matters, Grade 16 (Ti-0.05Pd) is another option where the specification allows it.
Is titanium Grade 7 resistant to hydrochloric acid?
Grade 7 resists dilute hydrochloric acid far better than Grade 2, especially at moderate temperatures. It is not intended for hot, concentrated HCl, where zirconium or tantalum may be required.
What is the price of titanium Grade 7 plate?
Grade 7 costs more than Grade 2 because of its palladium content. The price depends on thickness, size, quantity, cutting and certification. Send your requirement to kamlesh@dineshtube-india.com or call +91 83559 10913 for a current quote.
Which certificates come with Grade 7 sheets and plates?
Every supply comes with an EN 10204 3.1 mill test certificate showing heat number, chemical analysis and mechanical properties to ASTM B265. EN 10204 3.2 certificates and third-party inspection can be arranged on request.
