🧩 Product Overview
The GR1 Titanium Bar, also referred to as ASTM B348 Grade 1 Titanium Rod, is a commercially pure titanium product that offers superior corrosion resistance, excellent ductility, and unmatched biocompatibility. As the softest and most formable of all titanium grades, Grade 1 titanium is widely used in aerospace, chemical processing, marine environments, and medical fields.
With a minimum titanium content of 99.5%, this product meets the rigorous requirements of ASTM B348 and is known for its high strength-to-weight ratio, non-toxicity, and inert chemical behavior. These properties make it highly suitable for demanding environments, particularly those involving chloride-rich or acidic exposure.
Our GR1 Titanium Bar is manufactured under stringent quality control protocols and is available in a variety of diameters, lengths, and surface finishes to meet diverse project needs. From industrial heat exchangers to surgical implants, the versatility of GR1 Titanium makes it a preferred choice across industries.
🧪 Chemical Composition (ASTM B348 Grade 1)
| Element | Symbol | Maximum Content (%) |
|---|---|---|
| Titanium | Ti | Balance |
| Iron | Fe | 0.20 |
| Oxygen | O | 0.18 |
| Carbon | C | 0.08 |
| Nitrogen | N | 0.03 |
| Hydrogen | H | 0.015 |
The ultra-low levels of interstitial elements contribute to exceptional formability and weldability. These features are critical for both cold-forming operations and medical-grade machining.

📜 Quality Standards & Testing
Specify the required material standard and inspection documents for the order. Do not treat the following items as a single universal Grade 1 compliance package; material, condition, certificate scope and testing must be agreed separately.
- ASTM B348
- Confirm any AMS requirement against the actual grade, condition and strength level; AMS 4921 is not an automatic substitute for the Grade 1 reference properties shown here.
- For a medical-material requirement, specify its standard and revision and confirm applicability and batch documentation before ordering.
- If quality-system certification is required, confirm the certificate holder, validity and relevant scope before ordering.
- Specify the required EN 10204 document type and traceability scope in the inquiry.
- For NDT, specify method, coverage and acceptance criteria; technical applicability and availability require confirmation.
- Third-party inspection is subject to the agreed inspection scope and arrangement.
Additional certification or inspection requirements must be reviewed and confirmed in the quotation.
📦 Packaging & Shipping
- Vacuum packaging for medical applications
- Desiccant-sealed plastic with PE wrap
- Export-grade wooden crates
- Express or freight options (FOB, CIF, DAP)
