grade 1 titanium Mechanical Properties
| Property | Value | Unit |
|---|---|---|
| Tensile Strength, Ultimate | 240 MPa (34800 psi) | Minimum |
| Tensile Strength, Yield (0.2% offset) | 170 - 310 MPa (24700 - 45000 psi) | Range |
| Elongation at Break | 24% | Minimum |
| Reduction of Area | 35% | Typical |
| Hardness, Brinell (grade 1 titanium hardness) | 120 | Annealed |
| Hardness, Rockwell B | 70 | Annealed |
| Modulus of Elasticity | 105 GPa (15200 ksi) | In tension |
| Charpy Impact (V-notch) | 310 J (229 ft-lb) | Typical |
Low yield strength (170 MPa) and high elongation (24%) make titanium grade 1 the most formable titanium grade. Grade 1 titanium yield strength is ideal for cold bending and deep drawing.
titanium grade 1 density
| Property | Metric | English |
|---|---|---|
| Density (titanium grade 1 density) | 4.51 g/cc | 0.163 lb/in³ |
Titanium density is approximately half that of steel. A gr1 titanium pipe of the same dimensions weighs ~50% less than a steel pipe.
Key Advantages of gr1 titanium pipe tube
| Advantage | Explanation |
|---|---|
| High Corrosion Resistance | Superior to aluminum; resists chemicals, acids, and seawater. |
| Low Density | gr1 titanium pipe equals steel in strength but weighs much less. |
| Great Heat Transfer | Facilitates efficient thermal exchange – ideal for gr1 titanium heat exchanger. |
| Smooth Surface / Micro-finish | Provides elevated functionality and better texture. |
| High Formability | gr1 titanium forming/bending is excellent due to low yield strength. |
