| Property | Value |
|---|---|
| Ultimate Tensile Strength (min) | 345 MPa (50 ksi) |
| Yield Strength (0.2%, min) | 275 MPa (40 ksi) |
| Elongation (min) | 20 % |
- Minimum properties per ASTM B348 apply to bar up to 3 in (76 mm); larger sections are by agreement.
- Minimum properties per ASTM B265 apply to plate up to 1 in (25 mm) thick; thicker plate is by agreement.
- Density is a typical value, not a specification requirement.

Frequently Asked Questions
What is Grade 2 titanium used for?
Heat exchangers, marine hardware, chemical processing equipment and general industrial parts that need corrosion resistance with moderate strength.
What is the difference between Grade 2 and Grade 5 titanium?
Grade 2 is commercially pure, with a minimum tensile strength of 345 MPa (50 ksi). Grade 5 (Ti-6Al-4V) is an alloy with a minimum of 895 MPa (130 ksi) in the annealed condition, and is less formable.
