ASTM B338 Grade 9 Seamless Titanium Tube

📄 Product Overview

The ASTM B338 GR9 Tube is a Grade 9 seamless titanium-alloy tube made from Ti-3Al-2.5V, also known as Grade 9 Titanium. For condenser and heat-exchanger procurement, identify the required edition of ASTM B338 standards for the GR9 Seamless Titanium Tube, the final supplied condition and the tube dimensions. Confirm chemistry, mechanical properties and applicable inspection requirements against the ordered material and batch documents.

🔍 Alloy Composition and Material Characteristics

Ti-3Al-2.5V alloy is composed of approximately:

• Titanium (Ti): Balance

• Aluminum (Al): 2.5%–3.5%

• Vanadium (V): 2.0%–3.0%

This Grade 9 Titanium Tube belongs to the Ti-3Al-2.5V alloy family. Compare it with commercially pure Grade 2 using the intended dimensions, final material condition, service environment and required inspection criteria.

Key properties of ASTM B338 GR9 Tube:

• High strength-to-weight ratio – consider the ordered tube geometry and material condition in the component design.

• Excellent corrosion resistance – evaluate the actual process medium, concentration and temperature for marine or chemical service.

• Outstanding weldability – specify the welding process, preparation, shielding and joint inspection requirements.

• High fatigue strength – confirm the required fatigue assessment for the supplied condition and component design.

The following mechanical-property table is a catalogue reference for Grade 9 tube in an annealed condition. Check the listed standard-reference column against the ordered ASTM B338 edition, product dimensions and final condition; establish batch acceptance from the agreed specification and inspection documents.

📏 Mechanical Properties

Use these catalogue figures for an initial GR9 Seamless Titanium Tube enquiry. Confirm the final material condition, applicable requirements and actual batch results for the intended design.

⚙️ Manufacturing Process

For an ASTM B338 GR9 Tube order, confirm the production route and the final supplied condition. The following steps identify processing and inspection topics to discuss with the quotation:

1. Billet Preparation – confirm the billet route and required material identity and inspection records.

2. Extrusion or Rotary Piercing – confirm the applicable seamless-tube production route with the quotation.

3. Cold Drawing – confirm final dimensions, tolerances and the material condition after processing.

4. Annealing – identify the final annealed condition and the required mechanical-property acceptance criteria.

5. Surface Finishing – agree pickled or polished surface requirements and the inspection acceptance basis.

6. Final Inspection – specify the applicable ultrasonic, eddy-current or hydrostatic tests and reporting required for the ordered route and specification.

📐 Available Sizes and Customization

We offer Grade 9 Titanium Tubes in a wide range of sizes to meet diverse engineering requirements:

• Outer Diameter (OD): 6 mm – 114 mm

• Wall Thickness: 0.5 mm – 10 mm

• Length: Up to 6 meters, custom lengths available

• Tolerance: ±0.05 mm for OD, ±0.02 mm for wall thickness

For a non-standard size, provide OD, wall thickness, cut length, straightness and tolerances so the quoted dimensions and acceptance requirements can be confirmed.

🌊 Corrosion Resistance

Evaluate the Ti-3Al-2.5V Tube for the specified service environment, including:

• Seawater – state temperature, chloride content, exposure conditions and any required corrosion assessment.

• Oxidizing environments – identify the medium, concentration, temperature and exposure conditions.

• Mild reducing acids – provide the acid identity, concentration and temperature, including these details for dilute hydrochloric acid service.

• Chloride-containing solutions – assess the required corrosion and stress-corrosion criteria for the actual environment and loading.

Select the ASTM B338 Titanium Tube for marine, offshore or chemical-processing enquiries using the design conditions and agreed corrosion acceptance criteria.

🚀 Applications

The following sectors may use ASTM B338 GR9 Tube as a component-manufacturing material. Suitability depends on the design, ordered condition and applicable system or material requirements:

Aerospace

• Hydraulic and pneumatic systems

• Fuel and exhaust lines

• Aircraft structural components

Marine

• Boat frames and masts

• Offshore platform tubing

• Desalination plant piping

Chemical Industry

• Heat exchanger tubing

• Process piping for corrosive fluids

• Condenser systems

Sports and Recreation

• High-performance bicycle frames

• Golf club shafts

• Lightweight camping gear supports

📜 Compliance and Standards

For GR9 Seamless Titanium Tubes, distinguish the ordered material specification from condition-specific hydraulic references and company documentation:

• ASTM B338 – Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers

• AMS 4943 / AMS 4944 – confirm the requested hydraulic-tube specification and edition: AMS 4943 relates to annealed condition; AMS 4944 relates to cold-worked, stress-relieved condition.

• ISO 9001:2015 – if quality-management documentation is required, confirm the actual issuer, validity and scope separately from the product material specification.

🛠 Quality Assurance

For the ordered ASTM B338 GR9 Tube, identify the required inspection and reporting scope:

• Dimensional checks – OD, wall thickness, length

• Non-destructive testing – identify the ultrasonic or eddy-current method, acceptance criteria and reporting required by the order.

• Mechanical testing – Tensile, yield, elongation

• Chemical analysis – Verification of Ti-3Al-2.5V composition

State the required Material Test Certificate (MTC) type, heat or lot identification and chemical/mechanical reporting in the enquiry; confirm the document scope with the quotation.

📦 Packaging and Delivery

• Packaging: Polyethylene wrapping, capped ends, and seaworthy wooden cases.

• Delivery time: 15–25 days depending on order size.

• Shipping: Worldwide via air, sea, or courier.

• Export compliance: All shipments follow relevant export control regulations.

Grade 9 Tube Ordering Information and FAQs

For a condenser or heat-exchanger tube enquiry, provide ASTM B338 edition, Grade 9 / Ti-3Al-2.5V designation, seamless route, OD, wall thickness, cut length, straightness and tolerances, final annealed or specified condition, surface and end requirements, quantity, service medium and temperature, and the required heat or lot inspection documents. Send the drawing and acceptance requirements through our Contact page.

Which tube does this listing address? It is a Grade 9 seamless-tube enquiry using the condenser and heat-exchanger scope of ASTM B338. Confirm the ordered edition, dimensions, final condition and acceptance requirements.

How does it differ from CWSR Grade 9 tubing? Grade 9 identifies the alloy; CWSR identifies a cold-worked, stress-relieved material condition. For a condition-led enquiry, see our CWSR Grade 9 titanium tube.

What establishes batch acceptance? Use the agreed standard edition, final condition and required inspection documents. The catalogue table supports an initial enquiry; assess its applicability to the ordered lot.
