Gr1 titanium tube (also known as TA1) is a commercially pure titanium product valued for its excellent corrosion resistance, superior ductility, and impressive biocompatibility. These titanium alloy gr.1 tube products are manufactured to ASTM B338 standards and undergo rigorous quality inspections to guarantee consistent performance.

Grade 1 titanium mechanical properties
| Property | Value |
|---|---|
| Tensile Strength | ≥240 MPa |
| Yield Strength (grade 1 titanium yield strength) | 138-310 MPa |
| Elongation | 24% min |
Key gr1 titanium properties: Low yield strength and high elongation (24% min) make titanium grade 1 the most formable titanium grade. gr1 titanium forming/bending is excellent for complex shapes.
Titanium grade 1 applications
| Industry | Application |
|---|---|
| Chemical Processing | gr1 titanium heat exchanger, corrosive fluid transport, acid/alkali resistant piping |
| Medical | Medical grade 1 titanium (surgical implants, orthopedic devices, dental implants, endoscopic tools, catheters) |
| Aerospace | Hydraulic and pneumatic systems, exhaust ducts |
| Marine Engineering | Seawater systems, desalination, grade 1 titanium anode/cathode |
| Desalination | High-temperature fluid transfer, condensers |
gr1 titanium for chemical processing provides excellent resistance to acid and alkali attack. gr1 titanium MMO anode is standard for cathodic protection in marine environments. ASTM F67 grade 1 is required for medical implant applications.
FAQ
1. How does your Gr.1 tube compare to European brands?
It is technically equivalent. Our gr1 titanium pipe meets ASTM B338 with typical oxygen 0.12-0.15% and elongation 28-32%. Price is 15-25% lower for wholesale orders.
2. Is TA1 the same as Grade 1 titanium?
Yes. TA1 is the Chinese equivalent of ASTM Grade 1 titanium (UNS R50250, W.Nr. 3.7025). Both have identical composition and properties.
3. What is the difference between Grade 1 and Grade 2 titanium tube?
Grade 1 has lower yield strength (170 MPa vs 275 MPa) but higher ductility (24% vs 20% elongation). Choose gr1 titanium tube for bending; choose Grade 2 for higher pressure.
4. What filler metal for welding Gr.1 tube?
Use AWS A5.16 ERTi-1 filler. Shielding must be 100% argon with back purge. Clean surfaces with acetone before welding.
5. Is Gr.1 tube good for heat exchangers?
Yes. ASTM B338 Grade 1 is specifically designed for gr1 titanium heat exchanger tubes. Max service temperature is 300°C in water.
6. Can Gr.1 tube be used for medical implants?
No. Commercial ASTM B338 Gr.1 is not for implants. Use ASTM F67 Grade 1 (medical grade 1 titanium) with biocompatibility testing.
7. What is the minimum bending radius for Gr.1 tube?
1.5-2.0 x OD without mandrel; 1.0-1.5 x OD with mandrel. Bend in annealed condition. gr1 titanium forming/bending is excellent.
8. What are the key properties of Grade 1 titanium?
Titanium grade 1 density is 4.51 g/cm³. Grade 1 titanium yield strength is 170 MPa min. Elongation is 24% min. Hardness is 120 HB.
9. What is the current price per kg for Gr.1 pipe?
Contact us for gr1 titanium price per kg. Wholesale grade 1 titanium gets bulk discounts. Buy gr1 titanium in bulk for best pricing.
10. Can Gr.1 titanium be deep drawn?
Yes. gr1 titanium for deep drawing is excellent due to low yield strength and 24% elongation. Ideal for reactor heads and bellows.
11. Can Gr.1 tube be used for MMO anode?
Yes. gr1 titanium MMO anode is standard for cathodic protection. Bare grade 1 titanium anode/cathode is used as cathode.
12. What certifications do you provide?
Mill Test Certificates (EN 10204 3.1), ISO 9001, AS9100, PED, NACE MR0175. Third-party inspection available.
