GR2 vs GR1 Titanium Tubing
Both Grade 1 and Grade 2 belong to the commercially pure (CP) titanium family. Grade 2 offers higher mechanical strength while maintaining excellent corrosion resistance, making it the preferred choice for industrial tubing.
| Property | Grade 1 Titanium | Grade 2 Titanium |
|---|---|---|
| UNS Number | R50250 | R50400 |
| Material Type | Commercially Pure Titanium | Commercially Pure Titanium |
| Tensile Strength | ≥240 MPa | ≥345 MPa |
| Yield Strength | ≥170 MPa | ≥275 MPa |
| Elongation | ≥24% | ≥20% |
| Corrosion Resistance | Excellent | Excellent |
| Weldability | Excellent | Excellent |
| Formability | Excellent | Very Good |
| Typical Applications | Laboratory Equipment, Chemical Tanks | Heat Exchangers, Condensers, Precision Tubing, Marine Equipment |
Why Choose Grade 2?
Higher tensile and yield strength than Grade 1
