Choose the titanium bar route before comparing price

A broad request for titanium round bar is not enough to quote responsibly. Grade and ordered specification affect chemistry, mechanical requirements, condition, testing, certification, production route and usable machining allowance.

Titanium round bar and other bar sections

Round bar is the primary machining form on this hub. The table gives the confirmed factory capability envelope for round, square, flat and hexagonal bar. Availability still depends on grade, production condition, quantity, tolerance and the current production route; these ranges are not a live-stock promise.

FormFactory capability envelopeCondition or surfaceRFQ inputs to confirm
Round barØ1-500 mm; length ≤6000 mmRolled, forged, annealed, peeled, ground, polished or another agreed finish; separate documented precision centerless-ground route Ø3.175-25.4 mmDiameter, length, tolerance, straightness, machining allowance, end condition and UT scope
Square bar3×3-500×500 mm; length ≤6000 mm. Sections above this envelope are quoted as forged block up to 600 mm.As-produced, machined, ground or polished as quotedSide length, corner condition, section tolerance, straightness and surface

Hexagonal barAcross flats ≤17 mm; length ≤6000 mmFinish and condition by quotationAcross-flats size and tolerance, straightness, end cut and packing

Capability and order boundary: These ranges define the overall manufacturing envelope, not a claim that every grade, condition and tolerance is available at every size. An archived bar technical sheet lists 300-6000 mm for worked-condition random lengths and 300-2000 mm for annealed random lengths, with fixed or multiple lengths stated in the contract. The separate precision centerless-ground route is quoted to ±0.0127 mm (±0.0005 in) on diameter, tightening to ±0.0076 mm on request, with straightness of 0.5 mm per metre and 0.3 mm per metre on diameters up to 25 mm. The final size, route, tolerance and inspection combination must appear in the quotation and purchase order.

For a bar blank that also needs machining or additional inspection, review the titanium processing services alongside the finished drawing and machining allowance.

Inspection, traceability and export release

State the inspection and document scope before quotation; do not assume every order carries the same package.

  • Heat or lot identification linked to the applicable material certificate when required
  • Chemical and mechanical results to the ordered material specification
  • EN 10204 3.1 mill test certificate when included in the order
  • Ultrasonic, PMI, dimensional or third-party inspection when applicable and ordered
  • Grade, size, quantity and heat or lot marking on bundles or packages as agreed
  • Export packing and end protection confirmed by length, finish and shipment method

What titanium bar sizes can be supplied?

The manufacturing envelope covers round bar from 1 to 500 mm in diameter, square bar from 3 by 3 to 500 by 500 mm, flat bar from 3 by 12.7 to 30 by 500 mm, and hexagonal bar up to 17 mm across flats, all in lengths up to 6000 mm. Sections above this envelope are quoted as forged block up to 600 mm. Availability at a given size depends on the grade, production condition, tolerance and quantity, so the exact size and route are confirmed on the quotation rather than held as fixed stock.

What is the difference between Grade 5 and AMS 4928 titanium bar?

Both are Ti-6Al-4V (Grade 5); the difference is control. A general Grade 5 bar is ordered to a standard mill specification such as ASTM B348. An AMS 4928 bar is ordered to the aerospace specification, so the ordered revision, condition, test plan and certification package must follow AMS 4928. If the drawing or purchase order calls out AMS 4928, it is an AMS-controlled order and not a general Grade 5 purchase.

How ordering works for titanium bar

Bar availability and production are reviewed against each RFQ. The industrial round-bar route and the precision centerless-ground route are quoted separately, since they differ in input size, machining and inspection. On the precision centerless-ground route, different diameters of the same grade can be consolidated into one order. Quantity and schedule are confirmed in the quotation against the ordered grade, size, condition and document scope.

Orders to AMS 4928 or ASTM F136 are scheduled after the ordered revision, dimensions, testing, inspection and certification scope are reviewed. Ultrasonic inspection is included only when the specification, size range or purchase order requires it. Price follows grade, diameter, tolerance class, quantity, inspection scope and market conditions at quotation.

  • The capability table above gives the overall form and size envelope. The grade, condition, tolerance and inspection combination remains order-specific.
  • The precision centerless-ground program is a separate route with its own Ø3.175-25.4 mm diameter range. Its tolerance and straightness values do not extend to the general round-bar envelope.
  • ASME SB-348 adopts the corresponding ASTM B348 material specification. State the required ASME edition and Code context on the purchase order.

MOQ, stock and export scope: Minimum quantity, stock position, packing and lead time are confirmed in the quotation after the RFQ is reviewed.

Titanium Bar RFQ questions

Which standard applies to a titanium round bar?

ASTM B348 is a common industrial route for titanium and titanium-alloy bars and billets. AMS 4928, ASTM F67 or ASTM F136 applies only when that specification is ordered for the relevant grade and use. State the exact standard and revision before production.

Are titanium bar and titanium rod the same?

Buyer terminology varies. Diameter, section, manufacturing condition and governing specification are more reliable than the word rod. State the final dimensions and intended processing route so the quotation identifies the correct product form.

Does every Grade 5 bar meet AMS 4928?

No. A general Ti-6Al-4V Grade 5 order may follow ASTM B348 or another specification. AMS 4928 must be specified and reviewed with its ordered revision, condition, testing and documentation requirements.

What should I send for a comparable titanium bar quotation?

Send grade, standard and revision, diameter or section, length, condition, tolerance, surface, quantity, application, destination, inspection and certificate requirements. Add a drawing for a close-tolerance machined part.

More about Titanium Bar

Use the titanium bar grade selection guide, forms and tolerance guide and machining guide before release. The bar RFQ checklist and weight calculator help prepare dimensions and quantity. Export packing, heat or lot marking, MTC, EN 10204 3.1, UT, PMI and third-party inspection are included only when quoted and ordered.

Specification detail with sources

ASTM B348 sets the mechanical limits titanium bar is accepted against: annealed Grade 2 bar at 345 MPa minimum tensile strength with yield between 275 and 450 MPa, and Grade 5 Ti-6Al-4V bar at 895 MPa minimum tensile with 828 MPa minimum yield, tested per lot. On the implant side the UNS number follows the standard, not the grade name: Grade 23 bar under ASTM B348 is R56407, and only ASTM F136 assigns R56401, so a medical bar purchase order should quote the standard and UNS as a pair rather than assume they are interchangeable.

Beiyu Titanium supplies round bar from 1 to 500 mm diameter, square bar from 3 x 3 to 500 x 500 mm, flat bar from 3 x 12.7 to 30 x 500 mm and hexagonal bar to 17 mm across flats, all in lengths to 6,000 mm, with sections above that envelope supplied as forged block up to 600 mm. Beiyu holds bar diameter to the h6 through h9 or H6 through H9 tolerance classes and quotes condition by the R, M and Y codes of GB/T 2965 (hot-worked, annealed and cold-worked), so grade, section, tolerance class and condition code are the four entries Beiyu checks a bar RFQ against before quotation.

Two of those entries are decisions in their own right: section is settled in round, square, flat or hexagonal bar, and the tolerance class in how to state a diameter tolerance. Two further fields sit beside them on the same order line, the surface route in peeled, turned or ground bar and the cut in cut length and end condition.

The acceptance side of the same order line runs separately. Straightness and ultrasonic acceptance class are stated by the buyer rather than assumed, and where the bar is going into an implant the choice of specification is set out in F67 or F136 on the order line.
