Description
✅ GR1 Titanium Bar – Premium ASTM B348 Grade 1 Titanium Rod for Industrial & Medical Use
🧩 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.
