titanium grade 2 hardness
Dec 10, 2025
What is GR2 titanium material?
Titanium Grade 2 is a commercially pure titanium alloy known for its excellent corrosion resistance, high strength-to-weight ratio, and superior weldability. This material is widely used in industries requiring lightweight yet durable components, making it an ideal choice for fasteners in aerospace, marine, chemical processing, and medical applications. Titanium Gr 2 fasteners offer exceptional resistance to harsh environments, including saltwater and corrosive chemicals, ensuring long-term performance and reliability.
titanium grade 2 hardness
For standard, annealed Titanium Grade 2 (the most common condition), the typical hardness values are:
Rockwell B Hardness (HRB): 70 - 90 HRB (The most common industrial scale)
Brinell Hardness (HB): 120 - 180 HB
Vickers Hardness (HV): 150 - 200 HV
These values indicate that Grade 2 is a relatively soft, ductile, and formable metal, which is key to its widespread use.
| Condition | Typical Hardness (HRB) | Description |
|---|---|---|
| Annealed (Soft) | 70 - 85 HRB | The standard, most supplied condition. The material is fully softened by heat treatment, offering optimal ductility, toughness, corrosion resistance, and weldability. |
| Cold Worked / Hard | 85 - 100+ HRB | The material has been rolled, drawn, or worked at room temperature, causing "strain hardening." This increases strength and hardness but reduces ductility. The degree of cold work dictates the final hardness. |
| Per Specification | Often Max 90 HRB | Major standards like ASTM B265 (for plate/sheet) often specify a maximum hardness (e.g., 90 HRB) to ensure the material remains readily formable. |
