Grade Selection for Titanium Round Bar

The selection of titanium round bars depends on three key factors: working medium/temperature, strength/ductility requirements, and machining method. The most common decision is made between Grade 2 (Commercially Pure Titanium) and Grade 5 (Ti-6Al-4V), while other grades are used for specific corrosion-resistant or forming applications. Below are application-based recommendations, with quick links to each grade page for comparison and ordering.

Grade 2 Titanium Round Bar

Corrosion-resistant, weldable, formable — suitable for most structural components that do not require extremely high strength.

Standards: ASTM B348 / SB-348, ASTM F67

Applications: Chemical and marine equipment, pump shafts and valve stems...

Grade 5 (Ti-6Al-4V)

High strength-to-weight ratio, ideal for weight-sensitive parts requiring high load-bearing capacity.

Standards: ASTM B348 / SB-348, AMS 4928

Applications: Aerospace structural components, fastener blanks, high-strength shafts

Click to view stock list

Titanium Round Bar – Commercially Pure (CP Titanium)

Grade 1 (CP-1)

Highest ductility, lowest strength. Ideal for deep drawing, bending, expansion forming in chemical equipment and heat exchangers. Excellent weldability, reduces tooling and rework in large-formed parts.
Grade 3 (CP-3)

Higher strength than Gr2, with good corrosion resistance and weldability. Suitable for slightly higher-load chemical equipment parts and cost-sensitive structural components.
Grade 4 (CP-4)

Highest strength among CP grades. Suitable for high-stress components in corrosive environments. Common in chemical, marine applications, and pressure parts.

Titanium Round Bar – Titanium Alloys

Grade 6 (Ti-5Al-2.5Sn)

Offers good medium-temperature stability for temperature-sensitive components. Ideal when higher strength retention than Grade 5 is required, but without using high-temperature superalloys.
Grade 7 (Ti-0.15Pd)

Palladium addition significantly improves corrosion resistance in reducing acids and chloride environments. Commonly used for internal parts of chemical equipment; mechanical properties are similar to Grade 2.
Grade 9 (Ti-3Al-2.5V)

Medium strength and cold-formable, offering a balance of strength and workability. Widely used for lightweight structural components and tubing systems.
Grade 12 (Ti-0.3Mo-0.8Ni)

Enhanced resistance to crevice corrosion and hot halide environments, ideal for heat exchangers, reaction vessels, and tube sheet assemblies.
Grade 16 (CP-Ti + Pd)

Similar to Grade 7 in Pd-enhanced corrosion resistance but uses a CP titanium base. Ideal for upgrading chemical equipment where higher corrosion resistance is needed while maintaining good formability and weldability.
Grade 23 (Ti-6Al-4V ELI)

Based on Grade 5 with Extra Low Interstitials (ELI), offering superior fracture toughness and fatigue resistance. Used in medical implants and high fatigue-safety components.
Grade 20 (Beta-C)

High-strength β titanium alloy, suitable for high-load structures and critical connectors. Offers a better strength-toughness balance in extreme applications compared to conventional α-β alloys.
Ti-6242 (Ti-6Al-2Sn-4Zr-2Mo)

Offers higher medium-to-high temperature strength and creep resistance than Grade 5. Widely used in aerospace structures needing thermal stability, such as front hot-section parts and compressor casings.
Ti-5553 (Ti-5Al-5V-5Mo-3Cr)

High-strength β titanium alloy, suitable for load-bearing structures and high-strength fasteners. Mechanical properties can be finely controlled through quenching, tempering, and aging processes.

Frequently Asked Questions (FAQ)

Are you a manufacturer or a partnered production line? Can you supply one-stop service?

We operate with a "self-owned + partnered production line” model, covering open-die forging, hot extrusion, hot rolling, as well as TGP precision grinding and Hollow Bar (gun drilling + honing). Key processes can be recorded and third-party witnessed. A single-window supply approach makes project coordination easier and more reliable.

Not sure whether to choose Grade 2 or Grade 5 (or Grade 23)?

Start from "medium + strength.” • For chemical, seawater or other corrosive environments requiring good weldability → choose Grade 2. • For high-strength lightweight structures or fastener billets → choose Grade 5. • If toughness and fatigue reliability are critical → choose Grade 23 (ELI). Send us your working conditions, and we will recommend a practical and applicable grade.

What are the common stock sizes? Can you provide cut-to-length service?

Metric Ø3–Ø300 mm and imperial 1/8"–12" cover mainstream specifications. Cut-to-Length is available; standard cutting tolerance is ±1.0–2.0 mm, and precision cutting can be negotiated to ±0.5 mm. Popular sizes are supported with safety stock, and urgent orders can be inserted into production.

What tolerance and straightness can you achieve for assembly-level precision?

TGP (Turned, Ground & Polished) is available. Typical straightness can be controlled to ≤0.5 mm/m, and tolerances can be negotiated to h9/h10. End-face turning, chamfering, keyway or thread machining can be performed according to drawings.

Can you supply Hollow Bar? Is it suitable for valve bodies or sleeves?

Yes. Thick-wall Hollow Bars are manufactured through gun drilling + honing, which significantly reduces chips and machining time. Recommended bore diameter is ≥6 mm, minimum wall thickness ≥3 mm. Smaller dimensions may require rigidity and runout evaluation.

Which standards do you follow? What documents are provided with delivery?

Titanium bars comply with ASTM B348 / ASME SB-348. Aerospace applications follow AMS 4928 (Grade 5). Medical materials follow ASTM F67 / F136 / ISO 5832-3. Documents include EN 10204 3.1/3.2 (MTR), and optional UT (ASTM B594) / PT / RT inspection reports.

How is delivery scheduled? Do you provide export packaging?

We support small-batch quick delivery and stable batch production scheduling. Multiple-destination and split shipments are available. Export packaging includes reinforced wooden crates, end protection caps, VCI or clean packaging, with complete documentation and support for port inspection and customs clearance.
