GR1 Titanium Pipe & Tube – Technical Data Sheet
May 14, 2026
What Is Titanium Grade 1?
Pure titanium Grade 1 is characterized by very good ductility and, as a result, very good cold formability, which makes the material suitable for deep drawing. GR1 titanium is known for its excellent general and seawater corrosion resistance and offers high corrosion resistance in oxidizing, neutral and mildly reducing media (solutions) including chlorides. Titanium grade 1 has low density (about half that of nickel-based alloys), a high strength-to-weight ratio, and corrosion resistance.
Applications: Chemical and maritime industries, pharmaceuticals, medical technology. GR1 titanium pipe and GR1 titanium tube are widely used in heat exchangers, reactors, and marine piping systems.

FAQ
Q1: What is the difference in yield strength between GR1 titanium pipe and GR5 titanium bar?
A: GR1 titanium pipe has a minimum yield strength of 138 MPa. GR5 titanium bar (Ti-6Al-4V) has a minimum yield strength of 827 MPa. GR5 is significantly stronger.
Q2: What is the equivalent European standard for ASTM B338 grade 1 titanium tube?
A: The equivalent European standard for ASTM B338 grade 1 titanium tube is 3.7025 (DIN/EN designation) and ISO 5832-2 for medical applications.
Q3: Can GR1 titanium tube be used for bending and flaring in heat exchanger fabrication?
A: Yes. GR1 titanium tube has excellent ductility and can be bent, flared, and expanded. For tight radius bends, use a mandrel bender to prevent kinking.
Q4: What is the maximum oxygen content for ASTM B861 grade 1 titanium pipe?
A: The maximum oxygen content for ASTM B861 grade 1 titanium pipe is 0.18%. This low oxygen content ensures high ductility and corrosion resistance.
Q5: How does the price per kg of GR1 titanium pipe compare to GR2 titanium pipe?
A: GR1 titanium pipe price per kg is typically 5-10% higher than GR2 due to stricter oxygen control and higher ductility requirements. Contact supplier for current GR1 titanium price.
Q6: What welding filler metal is recommended for ASTM B862 GR1 titanium welded tube?
A: Use ERTi-1 filler wire for welding ASTM B862 GR1 titanium welded tube. ERTi-2 is also acceptable but will produce slightly higher strength weld metal.
Q7: Is titanium grade 1 suitable for seawater cooled heat exchanger tubes?
A: Yes. Titanium grade 1 has excellent seawater corrosion resistance and is widely used for titanium alloy GR1 tube in marine heat exchangers. No pitting or crevice corrosion occurs.
Q8: What is the density difference between titanium grade 1 and stainless steel 316L pipe?
A: Titanium grade 1 density is 4.51 g/cm³. Stainless steel 316L density is 8.00 g/cm³. GR1 titanium pipe weighs approximately 44% less than same-size 316L pipe.
Q9: Can GR1 titanium sheet be deep drawn into complex medical implant components?
A: Yes. Grade 1 titanium for deep drawing is the preferred material for complex drawn parts. Elongation of 24% minimum allows deep draws without intermediate annealing.
Q10: What is the difference between ASTM F67 grade 1 and ASTM B265 grade 1 titanium plate?
A: ASTM F67 grade 1 is specifically for surgical implant applications with stricter cleanliness and surface requirements. ASTM B265 grade 1 titanium plate is for general industrial use. Chemistry and mechanical properties are similar.
Q11: What is the typical lead time for customized GR1 titanium tube from a factory?
