ASTM B348 Titanium Alloy Bars

LINHUI Titanium provides high-quality ASTM B348 titanium alloy bars made for demanding industrial applications. We provide titanium-based alloys such Grade 5 (Ti-6Al-4V), Grade 9 (Ti 3Al-2.5V), Grade 12 (Ti-0.3Mo-0.8Ni), and Grade 23 (Ti 6Al-4V ELI) in addition to unalloyed titanium (Grades 1, 2, and 7).

Our bars are available in diameters ranging from Φ5mm to Φ350mm and lengths ranging from 300mm to 6000mm. They have strict EN 10204 3.1/3.2 certification and full heat number traceability. With over 200 tons of stock inventories and a normal manufacturing lead time of 15–25 days, we offer precision-engineered ASTM B348 Titanium Alloy Bars with ISO 9001:2015 quality assurance and PED 2014/68/EU certification for international markets.

Key Features & Benefits

Better Ratio of Strength to Weight

Grade 5 (Ti-6Al-4V) is 56% lighter than steel and has a tensile strength of 895 MPa at a density of only 4.43 g/cm³.

Outstanding Resistance to Corrosion

Where stainless steel fails, passive oxide layer production offers protection against oxidizing acids, chlorides, and seawater.

Longer Service Life

Grade 23 ELI provides ultra-high purity for biocompatible applications, while Grade 7 palladium-stabilized composition is resistant to reducing acids such as HCl and H₂SO₄.

Adaptable Personalization

For precise CNC machining, a variety of surface treatments are offered, including pickled, polished, and centerless ground.

Manufacturing Process

Selection of Raw Materials for ASTM B348 Titanium Alloy Bars

Consistent chemistry is ensured by using virgin titanium sponge from accredited mills.

VAR, or vacuum arc remelting

The double or triple melt procedure homogenizes the composition of the alloy and removes impurities.

Rolling and Hot Forging

Grain structure is refined via controlled deformation at 900–1100°C. To reach the desired dimensions, bars go through several processes.

Treatment with Annealing

Internal stresses are reduced while mechanical qualities are preserved by heat treatment at predetermined temperatures.

Precision Machining Tight diameter tolerances (±0.05mm for sensitive applications) are achieved using centerless grinding or peeling.

Quality Inspection

Chemical Evaluation

Alloy composition is confirmed by optical emission spectrometry in accordance with ASTM guidelines.

Mechanical Examination

Tensile, yield strength, and elongation testing were carried out in accordance with ASTM E8. Conformity is guaranteed via hardness testing.

100% NDT Examination

Internal flaws are found using eddy current testing (ET) and ultrasonic testing (UT). imposed a zero-defect policy.

Dimensional Confirmation

Diameter, straightness, and length tolerances are verified by CMM inspection.

EN 10204 3.1/3.2 Mill Test Certificates with complete heat number traceability are part of the certification package. There is access to third-party examination (SGS, BV, TÜV).

Applications Of ASTM B348 Titanium Alloy Bars

Aerospace Engineering

Structural components, landing gear, fasteners requiring high strength and low weight.

Chemical Processing

Heat exchangers, reaction vessels, piping systems exposed to corrosive media.

FAQ

Q: How is ASTM F136 different from ASTM B348?

A: ASTM B348 covers both industrial and aviation uses. ASTM F136 mandates Ti-6Al-4V ELI (Grade 23) for medical implants with stricter interstitial limitations that ensure biocompatibility.

Q: Do you provide annealed bars?

A: To reduce internal tensions, normal supply is indeed annealed. For applications requiring greater strength, cold-worked or solution-treated conditions are available upon request.

Q: Is it possible to weld Grade 5 bars?

A: In order to avoid oxygen pickup, there is controlled inert gas shielding. Compared to Grade 5, Grade 2 is simpler to weld.

Q: Which surface treatments are available?

A: Centerless ground/polished for precision CNC applications, pickled (cleaned with acid), peeling (roughly machined), and black (as-forged).

Q: How can I verify that the substance is genuine ASTM B348?

A: Always seek an EN 10204 3.1 Mill Test Certificate that connects the heat number to the outcomes of mechanical and chemical testing, as mandated by ASTM B348.

Q: What is the turnaround time for custom sizes?

A: The shipping time for stock orders is three to seven days. Custom manufacture takes 25 to 40 days, depending on the specifications.
