Titanium Grade 12 (Ti-0.3Mo-0.8Ni) Sheet, Plate and Strip to ASTM B265
Dinesh Tube India supplies and exports titanium Grade 12 sheets, plates and strip from Mumbai to desalination, chlor-alkali, salt and chemical plants, and to heat-exchanger and vessel fabricators in India, the Middle East and beyond. Grade 12 (UNS R53400, Werkstoff 3.7105) is titanium with about 0.3% molybdenum and 0.8% nickel, supplied to ASTM B265 / ASME SB265 with EN 10204 3.1 mill test certificates.
The small Mo and Ni additions give Grade 12 much better resistance to crevice corrosion in hot chloride brines than Grade 2, plus about 40% higher strength, at lower cost than palladium-bearing Grade 7. For other titanium grades, see our titanium sheets and plates page.
Titanium Grade 12 vs Grade 2 vs Grade 7
| Point | Grade 2 | Grade 12 | Grade 7 |
|---|---|---|---|
| Alloying | None (CP) | Mo 0.2–0.4, Ni 0.6–0.9 | Pd 0.12–0.25 |
| Min. tensile / yield | 345 / 275 MPa | 483 / 345 MPa | 345 / 275 MPa |
| Crevice corrosion in hot brines | Fair (risk above about 70–80 °C) | Excellent | Excellent |
| Dilute reducing acids (HCl, H2SO4) | Poor to fair | Good | Best |
| Cost | Lowest | Moderate | Highest (palladium) |
| Choose it for | General seawater and chloride service | Hot brines and crevice-prone joints at moderate cost | Strongly reducing acids |

Why Titanium Grade 12 in Hot Brines?
Grade 12 resists seawater, wet chlorine, hypochlorite, nitric acid and most oxidising media like Grade 2. In strongly reducing acids, Grade 7 is the better choice. Like all titanium, Grade 12 is not suitable for hydrofluoric acid, fluorides or dry chlorine gas. See the full guide on our titanium sheets and plates page.
Grade 12 Sheet Weight Calculation
Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 4.51
For example, a 2000 × 1000 × 3 mm Grade 12 sheet weighs about 2 × 1 × 3 × 4.51 = 27 kg.

Titanium Grade 12 Sheets & Plates: FAQs
What is titanium Grade 12?
Titanium Grade 12 (UNS R53400, Werkstoff 3.7105) is a titanium alloy with about 0.3% molybdenum and 0.8% nickel. It is supplied as sheet, plate and strip to ASTM B265 / ASME SB265 and is known for its resistance to crevice corrosion in hot chloride brines.
What is the chemical composition of titanium Grade 12?
Per ASTM B265: molybdenum 0.2–0.4%, nickel 0.6–0.9%, 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 12 and Grade 2?
Grade 2 is commercially pure titanium. Grade 12 adds Mo and Ni, raising minimum tensile strength from 345 to 483 MPa and greatly improving resistance to crevice corrosion in hot brines, where Grade 2 can fail.
Should I choose Grade 12 or Grade 7?
Both resist crevice corrosion in hot chlorides. Grade 7 contains palladium and is better in strongly reducing acids, but costs more. Grade 12 is stronger and is the lower-cost choice for most hot-brine and desalination service.
Can titanium Grade 12 be welded?
Yes. It is welded by GTAW with full argon shielding, like commercially pure titanium, using matching Grade 12 filler wire.
What is the price of titanium Grade 12 plate?
The price depends on thickness, size, quantity, cutting and certification, and is higher than Grade 2. Send your requirement to kamlesh@dineshtube-india.com or call +91 83559 10913 for a current quote.
Which certificates come with Grade 12 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.
