Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Bar and round-rod naming | Grade 4 titanium bars and Grade 4 pure titanium round rod are consolidated on this page. Round rod is a circular bar form; the approved order defines actual section and dimensions. |
|---|---|
| Material 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. |
| Ordering definition | State ASTM B348/B348M or ASME SB348, round or other section, dimensions, length, condition, surface, straightness, tolerances, quantity and end use. |
| Quality evidence | Request MTC, heat traceability, chemistry and mechanical results, dimensional and straightness inspection, surface acceptance and any supplementary NDE. |
