Product Detail
Product Introduction
Source ASTM B348 Grade 23 Ti-6Al-4V ELI titanium bar in UNS R56407 with defined dimensions, condition, inspection, MTC and heat traceability. Final supply is controlled by the grade, specification revision, dimensions, condition, tolerance, inspection and documentation stated on the approved order.
Which Grade 23 titanium bar route should be ordered?
Selection answer: Use ASTM B348 Grade 23 / UNS R56407 for the applicable commercial bar or billet scope. Use ASTM F136 / UNS R56401 only when wrought annealed Ti-6Al-4V ELI source material for surgical implant manufacture and its additional requirements are expressly required.
Selection boundary: Do not use Grade 23, ELI or medical grade as interchangeable shorthand. Product form, UNS, condition, metallurgy, downstream manufacturing, quality system and regulatory responsibility must be defined.
RFQ data to confirm: Send exact specification and revision, UNS, product form and dimensions, condition, application, machining allowance, UT and metallurgical tests, regulatory documents, MTC, quantity and destination for technical review.
Product Specifications
| Product | ASTM B348 Grade 23 Ti-6Al-4V ELI Titanium Bar | Grade | Grade 23 / Ti-6Al-4V ELI / UNS R56407 |
|---|---|---|---|
| Standard | ASTM B348/B348M covers annealed titanium and titanium-alloy bars and billets and identifies Grade 23 as UNS R56407, Ti-6Al-4V with extra-low interstitial elements. ASTM F136 surgical-implant source material is UNS R56401 and is a separate specification. State the exact revision, product form, UNS, dimensions, tolerances, condition, surface and required supplementary tests. | Size & Form | Round bar and cut blanks; size range and grain-flow requirements are reviewed per RFQ |
| Tolerance | Applicable material standard or customer drawing; ground tolerances available | Supply Condition | Annealed, forged, rolled, peeled or ground |
| Inspection | Verify the ordered UNS and specification, heat identity, chemistry including interstitial limits, tensile properties and test orientation, dimensions, straightness, surface, marking, MTC and heat/lot traceability. Define UT, microstructure, cleanliness, fracture, fatigue, medical-quality or aerospace documentation only from the governing specification and drawing acceptance criteria. | Documents | MTC, heat/lot traceability and agreed inspection reports |

Services We Can Provide
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 components
Material grade, dimensions, condition and inspection must be matched to the application requirements.

High-performance precision parts
Material grade, dimensions, condition and inspection must be matched to the application requirements.

Medical and surgical instruments when the expressly required material specification supports the use
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Grade 23 Titanium Bar MOQ, Pricing and Material Selection
MOQ Review
MOQ depends on the exact specification, UNS designation, diameter, condition, length and total order weight. State the annual or project quantity if repeat supply is expected.
Bulk Price Factors
Diameter, hot-worked or finished condition, machining allowance, tolerance, straightness, ultrasonic or metallurgical testing, traceability, packing and destination all affect the quotation.
Lower-Cost Alternatives
Grade 5 may be evaluated only when the design does not require Grade 23 ELI limits. ASTM B348 UNS R56407 and ASTM F136 UNS R56401 must not be treated as interchangeable certificate descriptions.
What to Send for an Accurate Bulk Quote
- ASTM B348, ASTM F136 or the exact project specification and revision
- UNS designation, bar form, diameter or section and length
- Condition, tolerance, straightness and machining allowance
- Quantity or total weight, required delivery schedule and destination
- UT, microstructure, MTC, traceability and other acceptance requirements
FAQ
Is ASTM B348 Grade 23 bar the same as ASTM F136 rod?
No. ASTM B348 Grade 23 is identified as UNS R56407. ASTM F136 implant-manufacturing material is UNS R56401 and has separate chemical, mechanical and metallurgical requirements. They must not share one certificate description.
How does Grade 23 bar differ from Grade 5 bar?
Both are Ti-6Al-4V families, but Grade 23 specifies extra-low interstitial limits. The exact standard, UNS, condition, properties and quality requirements determine whether either is acceptable.
What information is needed to quote Grade 23 bar?
Provide ASTM B348, ASTM F136 or other exact specification and revision, UNS, round or other bar form, diameter or section, length, condition, tolerance, straightness, application, UT or metallurgical tests, MTC, quantity and destination.
