| Carbon (C) | – | 0.08 |
| Iron (Fe) | – | 0.25 |
| Oxygen (O) | – | 0.20 |
| Nitrogen (N) | – | 0.05 |
| Hydrogen (H) | – | 0.0125 |
| Yttrium (Y) | – | 0.005 |
| Titanium (Ti) | Balance | – |
Other elements (each) must not exceed 0.1%, and total other elements must not exceed 0.4%.
Mechanical Properties
| Property | Value (Annealed Condition) |
|---|---|
| Tensile Strength (minimum) | 860 MPa (125,000 psi) |
| Yield Strength (0.2% offset, minimum) | 795 MPa (115,000 psi) |
| Elongation (minimum) | 10% in 4D |
| Reduction of Area (minimum) | 25% |
These properties highlight the alloy’s suitability for high-stress environments in the human body, such as joint replacements and other load-bearing orthopedic applications. The specific values can vary slightly based on the product form (e.g., bar, wire, sheet) and the exact heat treatment used.
