Grade 2 Titanium Hardness
Dec 09, 2025
What is GR2 titanium material?
Titanium Grade 2 is a pure alpha titanium and is the most widely used titanium alloy in all product forms for industrial service because of moderate strength and excellent corrosion resistance and formability. Compared to the other grades of commercially pure titanium, Grade 2 is slightly weaker than Grade 3, but stronger than Grade 1 and equally resistant to corrosion. Grade 2 offers excellent balance of moderate strength and reasonable ductility. This material is also non-magnetic.
grade 2 titanium hardness
The hardness of Grade 2 Titanium, commercially pure (CP) titanium, typically ranges between 150 - 210 Brinell (HB) or 70 - 95 Rockwell B (HRB). The exact value depends on its material condition (temper) and processing history.
Typical Hardness Values by Condition
| Condition / Temper | Brinell Hardness (HB) | Rockwell Hardness | Vickers Hardness (HV) | Key Characteristics |
|---|---|---|---|---|
| Annealed | 150 - 175 HB | 70 - 85 HRB | ~150 - 170 HV | Most Common Supply State. Optimal ductility and formability. |
| Cold Worked (e.g., 1/4 Hard) | 175 - 195 HB | 85 - 92 HRB | ~170 - 190 HV | Moderately increased strength, reduced ductility. |
| Cold Worked (Full Hard) | 195 - 210+ HB | 92 - 100+ HRB | ~190 - 210+ HV | Maximum strength from cold work, limited formability. |

Industries & Applications
Titanium Grade 2 has a lower density making it very desirable where weight can be a concern. Medical and aerospace are two key industries for titanium alloys. The strength and corrosion resistance properties of titanium Grade 2 also make it well suited to applications in the marine, chemical processing and desalination industries. Typical applications for Grade 2 titanium include oil & gas components, reaction and pressure vessels, tubing or piping systems, heat exchangers, liners, flue-gas desulphurization systems and many other industrial components. Continuous service temperatures can reach up to 800°F with occasional, intermittent service at 1000°F.
