Product Detail
Product Introduction
Source Grade 5 Ti-6Al-4V titanium round bar for aerospace, marine and industrial parts, with inspection and traceability options. Final supply is controlled by the grade, specification revision, dimensions, condition, tolerance, inspection and documentation stated on the approved order.
How should Grade 5 Ti-6Al-4V titanium bar be specified for bulk purchasing?
Selection answer: Start with the exact governing specification and revision, such as ASTM B348 Grade 5 or AMS 4928, then define diameter, length, condition, surface, tolerance and quantity. The Ti-6Al-4V alloy name alone is not a complete purchasing description.
Selection boundary: Grade 2 is not a direct lower-cost substitute when strength, fatigue performance or approved material qualification controls the design. Grade 23 is also not an automatic upgrade because its specification, interstitial limits, testing and application controls differ.
RFQ data to confirm: For quotation review, provide the finished-part envelope or stock size, machining allowance, straightness, heat-treatment condition, ultrasonic or surface-examination requirements, certificate package, total weight and destination.
Product Specifications
| Product | Grade 5 Ti-6Al-4V Titanium Round Bar | Grade | Grade 5 / Ti-6Al-4V / UNS R56400 |
|---|---|---|---|
| Standard | ASTM B348; applicable aerospace orders may reference AMS 4928 | Size & Form | Round bar and cut blanks; diameter, length and machining allowance are quotation-controlled |
| Tolerance | Mill tolerance or customer drawing; ground tolerances available after technical review | Supply Condition | Annealed, hot rolled, forged, peeled or centerless ground |
| Inspection | Chemical and mechanical testing, dimensional and visual inspection, traceability; UT where required | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Specification and condition | State ASTM B348, AMS4928 or another approved specification and revision expressly. Grade 5 / UNS R56400 alone does not define heat treatment, section-dependent properties or aerospace documentation. |
|---|---|
| Section and test orientation | Provide diameter, length, condition, test location and orientation, minimum mechanical properties and any macrostructure, microstructure or ultrasonic quality requirement. |
| Machining and fatigue control | Define finished-part envelope, stock allowance, straightness, surface condition, thermal-cut restrictions and handling of fatigue-critical surfaces or alpha-case removal. |
| Inspection package | Request MTC, melt and heat traceability when required, dimensions, chemistry and tensile reports, UT class, surface examination and third-party witness points. |
| Alloy-name boundary | Ti-6Al-4V names an alloy family, while ASTM B348 Grade 5, ASME SB348 and AMS 4928 are specification-controlled order descriptions. State the exact required standard and revision. |
| TC4 certificate boundary | TC4 is not automatically certified as ASTM Grade 5. Cross-standard acceptance requires document-level comparison of chemistry, condition, mechanical properties, testing and traceability. |

Product Packaging
Bars and rods are separated by grade and heat, protected against surface damage and secured in bundles or export cases with identification and traceability labels. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
Aerospace structures
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Marine and motorsport components
Material grade, dimensions, condition and inspection must be matched to the application requirements.
High-strength fasteners
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Is Ti-6Al-4V bar always ASTM Grade 5?
No. Ti-6Al-4V describes an alloy family. The purchase order must state ASTM Grade 5, AMS 4928 or another exact specification, revision and condition.
Can TC4 certificates replace ASTM B348 Grade 5 certificates?
Not automatically. TC4 belongs to the same nominal alloy family, but chemistry limits, condition, properties, testing and documentation must be checked against the required ASTM or AMS specification.
What information is required for a Grade 5 bar RFQ?
Provide the standard and revision, Grade 5 / UNS R56400, section, dimensions, condition, quantity, application, machining allowance, tests and required documents.
