Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Grade identity | Titanium Grade 4 / UNS R50700 is the highest-strength commonly specified commercially pure ASTM titanium grade. It is not Ti-6Al-4V Grade 5. |
|---|---|
| Specification stack | State ASTM B381 / ASME SB381 Grade 4, flange dimensional standard or drawing, class, facing, bore, type, forging condition and NDE. |
| Selection boundary | Choose Grade 4 only after reviewing strength, formability, weld procedure, corrosion service and material availability against Grade 2 or Grade 3. |
| Documentation | Request Grade 4 chemistry and tensile results, heat and forging traceability, dimensions, facing and bore inspection and required surface or volumetric NDE. |
