High Purity GR1 Titanium Bar
Apr 14, 2026
High Purity GR1 Titanium Bar refers to a bar-shaped material made of titanium metal. Titanium is a chemical element that is widely used in various applications, including aerospace, automotive industry, medical equipment, chemical equipment, etc., due to its lightweight, high strength, and corrosion resistance.
High Purity GR1 Titanium Bar is usually made of pure titanium or titanium alloys. High Purity GR1 Titanium Bar is made of titanium metal with high purity, which has high corrosion resistance and good machinability. Titanium alloy bars are made by alloying titanium with other metal elements (such as aluminum, vanadium, zinc, etc.) to improve the performance of titanium, such as increasing strength, high-temperature resistance, etc.

Products Features
High strength and lightweight: Titanium rods have excellent strength, comparable to steel, yet are lightweight metal. This makes titanium rods excellent in applications that require strength but also require reduced weight, such as aerospace and sports equipment manufacturing.
Excellent corrosion resistance: Titanium rods have good corrosion resistance to various corrosive media such as oxidation, acid, alkali and seawater. In contrast, steel is prone to rust and corrosion in these environments, so titanium rods are widely used in chemical equipment, marine engineering and seawater treatment, and other fields.
Biocompatibility: Titanium rods have good biocompatibility with human tissue and will not cause obvious immune reactions or rejection. This makes titanium rods widely used in implants, prosthetics and dental implants in the medical field.
High-temperature stability: Titanium rods can maintain their strength and stability in high-temperature environments, and have good high-temperature resistance. This makes titanium rods widely used in aerospace, energy industry and high-temperature process applications.
FAQ –High Purity GR1 Titanium Bar (ASTM B348 / UNS R50250 / 3.7025)
Q1: What is the difference between ASTM B348 GR1 titanium bar and ASTM B348 GR2 titanium bar?
A: ASTM B348 GR1 has lower tensile strength (240 MPa) and higher ductility (24% elongation). ASTM B348 GR2 has higher tensile strength (345 MPa) with 20% elongation. GR1 is easier to form and machine; GR2 offers higher strength for pressure-bearing applications.
Q2: What are the equivalent specifications for UNS R50250 titanium bar?
A: UNS R50250 is equivalent to DIN 3.7025, ASTM B348 Grade 1, ASTM F67, and ASME SB348. All refer to commercially pure titanium with maximum 0.18% oxygen content.
Q3: What is the difference between ASTM B348 GR1 titanium bar and ASTM F67 GR1 titanium bar?
A: ASTM B348 is the general standard for titanium bars for industrial applications (aerospace, chemical, marine). ASTM F67 is specifically for unalloyed titanium for surgical implant applications. Both have similar chemical composition, but ASTM F67 has additional biocompatibility requirements.
Q4: What fabrication methods are suitable for High Purity GR1 titanium bar?
A: GR1 titanium bar is ideal for cold forming, bending, machining (turning, milling, drilling), and welding (GTAW/TIG). For welding, strict argon shielding is required to prevent oxygen contamination and embrittlement.
Q5: What diameter range is available for ASTM B348 GR1 titanium round bar from GNEE?
A: GNEE supplies GR1 titanium bar in diameters from 8mm to 400mm and lengths up to 6000mm. Square, rectangle, and hexagon shapes are also available. H7/h7 tolerance is available upon request.
Q6: What surface finishes are available for GR1 titanium bar (3.7025)?
A: Available finishes include black (as-forged), pickling (acid-cleaned to remove scale), and sand-blasting (matte uniform finish). Polished finish is also available for titanium square bar stock.
Q7: What certificates does GNEE provide for ASME SB348 GR1 titanium bar?
A: GNEE provides ISO 9001:2015, EN10204 Type 3.1 MTC (Mill Test Certificate), and EN10204 Type 3.2 MTC (third-party inspected). Full traceability to the original heat number is included.
Q8: Is GR1 titanium bar suitable for medical implant applications?
A: Yes, GR1 titanium bar per ASTM F67 is suitable for medical implants due to its biocompatibility and good acceptance by human tissue. It is used for implants, prosthetics, and dental implants.
Q9: What is the maximum operating temperature for High Purity GR1 titanium bar?
A: GR1 titanium bar maintains strength and stability in high-temperature environments. It provides creep resistance up to 300°C and can be used in applications up to 400°C for short-term exposure.
Q10: What is the difference in oxygen content between GR1 (3.7025) and GR2 (3.7035) titanium bar?
A: GR1 has maximum 0.18% oxygen. GR2 has maximum 0.25% oxygen. The higher oxygen content in GR2 contributes to its higher strength (345 MPa vs 240 MPa) but slightly lower ductility (20% vs 24% elongation).
GR1 Titanium Product Testing
We back every titanium shipment with comprehensive in-house testing. Our laboratory is equipped with a Spectro spectrometer for precise chemical composition analysis, tensile and creep endurance testing machines for mechanical property verification, X-ray and fluorescent penetrant inspection for internal and surface defect detection, and coordinate measuring machines for dimensional accuracy. Every batch is tested before release, ensuring full traceability and compliance with applicable ASTM standards (such as B265, B338, B348, etc.). You don't just get titanium - you get documented quality.
Our factory
Our factory is equipped with core processing machinery for titanium products. For melting and forming, we use vacuum arc remelting (VAR) furnaces and a 2,500-ton hydraulic press. The billet processing line includes a high-temperature rolling mill and a radial forging machine capable of producing bars and rods from 8mm to 300mm in diameter. For seamless titanium tubes, we operate three-roll piercing mills and cold pilger rolling mills (LG-60, LG-90). Titanium plates and strips are produced on a four-high cold rolling mill with an online annealing furnace. For wires, we have a continuous wire drawing line with in-line degreasing and spooling units. All key equipment is CNC-controlled, ensuring consistent dimensional accuracy and surface finish for tubes, plates, bars, wires, and strips.
