Titanium Bar & Rod Manufacturer | Grade 2, 5 & 23 Round & Flat Bar Stock — TIALLOY
Titanium bar and rod fail in service more often for a single reason: the wrong grade for the working medium, or a melt source the buyer couldn’t verify. Since we melt, forge and roll titanium bar and rod in-house across Grades 1 through 23, you specify a grade and we ensure the interstitial chemistry and heat number stamped on the bar trace back to a single accountable source.

Where Grade and Melt Source Decide Your Cost and Risk
Titanium bar and rod isn’t a commodity purchased solely by diameter and price. That same 25mm round bar can be commercially pure Grade 2 or Ti-6Al-4V Grade 5 – alloys whose yield strength varies by roughly a factor of three, and whose corrosion behaviour in a reducing acid could be the difference between a ten-year vessel and a six-month failure.
Two procurement blunders cost more buyers more than anything else. They pick the wrong grade for the medium and later realize the corrosion data was available too late. Or, they source from a stockist who re-sells a competitor’s mill certificate and can’t account for the material’s actual melt origin.
That first mistake is costly because the interstitial oxygen that dictates fracture toughness is locked in at the melt, not on the shelf. TIALLOY controls it in-house to the 0.13% ceiling that Grade 23 demands, something a stockist can’t do with whichever interstitial chemistry arrived at their facility. Share your service conditions and target spec, and we’ll match the grade before pricing.
Titanium Bar & Rod Grades, The Grade-to-Medium Matrix
A myth to slay immediately: Grade 5 titanium bar isn’t lighter than Grade 2. Both densities sit around 4.4 to 4.5 g/cm³ and their stiffness is nearly identical. The difference is that Grade 5 is much stronger, its yield strength is about three times that of Grade 2, so you carry the same load with a thinner section.
And that distinction is key because your grade selection decision involves a trade-off between corrosion resistance and strength, not marketing fluff. Commercially pure Grades 1, 2, 7, and 12, are the workhorse corrosion alloys that comprise the vast majority of industrial titanium usage, far exceeding the higher strength aerospace alloys.
| Grade | UNS / Alloy | Spec | Key property | Best-fit medium / application |
|---|---|---|---|---|
| Grade 2 | R50400 (CP) | ASTM B348 | Weldable workhorse; yield ~275–345 MPa | Seawater & oxidising media, pressure vessels, heat-exchanger tube sheets, marine & chemical parts |
| Grade 1 | R50250 (CP) | ASTM B348 | Softest CP; best formability & corrosion | Anode material, electroplating, deep-drawn & non-load parts |
| Grade 7 | R52400 (Ti-0.15Pd) | ASTM B348 | Best corrosion of the CP class (Pd) | Reducing acids, chlorides, crevice corrosion — chlorine & wet-chemical service |
| Grade 12 | R53400 (Ti-0.3Mo-0.8Ni) | ASTM B348 | Stronger than Gr2, weldable | Hot acids & brines, heat exchangers, refinery & downhole service |
| Grade 5 | R56400 (Ti-6Al-4V) | ASTM B348 / AMS 4928 | ~895 MPa UTS, ~828 MPa YS (annealed) | High-strength structural, drive shafts, fasteners, engine & precision machined parts |
| Grade 23 | R56401 (Ti-6Al-4V ELI) | ASTM F136 / B348 | Extra-low interstitial; O max 0.13% | Fracture-critical parts; medical-grade material for a buyer’s qualified supply chain |
| Grade 9 | R56320 (Ti-3Al-2.5V) | ASTM B348 | Mid-strength, cold-formable | Lightweight structural, hydraulic lines, the practical tube-drawing alloy |
| Grade 4 | R50700 (CP) | ASTM B348 | Highest-strength CP grade | High-strength corrosion parts where an alloy is not required |
How to read this matrix for your part
Two on-the-ground engineering insights you don’t find in catalogue pages. Grade 2 is gummy – it clings to the cutting edge and creates long, stringy burrs, so it prefers sharp tooling and steady feed rates. Grade 5 traps heat and work-hardens instantly if a tool dwells. And the tubing trap: Grade 5 titanium tube is rare and expensive to draw, which makes Grade 9 the go-to choice.
- Reducing or acidic environment? Start with Grade 7, Grade 12 for hot acids/brines-the Pd and Mo-Ni additives buy your corrosion margin.
- Strength-limited structural part? Go Grade 5, and specify the condition (annealed ~130 ksi UTS; solution-treated-and-aged can be 140-170 ksi, section-size dependent).
Another one that determines fracture-critical work: by restricting maximum oxygen to 0.13% against Grade 5’s 0.20%, Grade 23 ELI buys the fracture toughness needed by thin, highly-stressed sections. It’s a melt chemistry, not machining, decision – which is why melt source is so critical.
- Fracture-critical or medical-grade material? Specify Grade 23 ELI; that lower oxygen ceiling is the whole point.
- General seawater or weldable service? Reach for Grade 2, the reason it’s the workhorse default.
Titanium Forms, Sizes & Specifications For Precision Manufacturing
We supply titanium bar and rod in the geometries that fabricators actually require, cut from mill stock. Titanium round bar and rod have the broadest application; flat, square, hex and hollow bars are covered by the same grade and specification menus.
Titanium round bar & rod
Ø6–400 mm titanium rod and round bar, from small-diameter rod through large forged bar, annealed, cold-worked, or centreless-ground. Ask us for titanium round bar sizes against your drawing.
Titanium flat bar & square bar
Rolled or forged titanium flat bar and titanium square bar stock for machined blanks and structural sections.
Titanium hex bar & hollow bar
Titanium hex bar for fasteners and fittings; titanium hollow bar and threaded bar to reduce machining loss on sleeve and ring parts.
Cut & finish
Saw cut-to-length, chamfering, grinding, and peeled/turned surface conditions per grade and order.
Specifications are assigned to grades and markets, not applied broadly. The following chart links standards to each material grade.
| Standard | Covers | Applies to |
|---|---|---|
| ASTM B348 / B348M | Titanium & titanium alloy bars and billets (Grades 1–38) | Industrial round, flat & forged bar across all CP and alloy grades |
| AMS 4928 | Ti-6Al-4V bar, wire, forgings, rings — annealed, 130/120 ksi min | Grade 5 bar for demanding non-defense / commercial-aerospace work, within the standard’s stated size scope |
| ASTM F136 | Ti-6Al-4V ELI material for surgical implant applications | Grade 23 bar as material conformance for a buyer’s qualified device supply chain |
| ASTM F67 | Unalloyed titanium for surgical implant applications | CP grade material conformance (medical) |
| AMS 4911 / 4965 / MIL-T-9047 | Plate & additional Ti-6Al-4V product/condition specs | Companion specs where an order calls them out |
Here’s a precision detail for your incoming inspection: any specification is valid only within its applicable size and form parameters. If you’re ordering ASTM B348 (ASME SB-348) Grade 5 or Grade 5 titanium bar stock, each item on the mill test report references its specific standard and revision, no blanket spec lines cover all sizes.
Mill-Direct Manufacturer vs Distributor, Why the Melt Source Matters
Almost all other titanium bar suppliers you’ll find are distributors or stocking houses. They purchase finished mill products, then resell them. That’s a valid business model, but it limits their ability to answer the one question that decides Grade 23 and AMS 4928 quality: who made the melt?
Titanium readily forms unstable compounds with oxygen and nitrogen at melt temperatures. The industry-standard solution is vacuum arc remelting (VAR), a process that removes dissolved hydrogen and nitrogen, cleans up oxide inclusions, and eliminates the compositional segregation that degrades mechanical property consistency. It’s essential for aerospace and medical applications demanding the highest homogeneity.
| Sourcing factor | Mill-direct manufacturer (TIALLOY) | Distributor / stockist |
|---|---|---|
| Melt & interstitial control | VIM / VAR / ESR in-house; O/N/H managed to grade | None — buys finished stock |
| Mill test report | Own EN 10204 3.1, tied to our heat numbers | Pass-through of a third party’s certificate |
| Grade / size range | Custom grades & sections to order | Catalogue SKUs on hand |
| Bulk economics | Mill pricing on volume & OEM runs | Retail / per-piece markup |
| Traceability chain | Melt → forge → roll → bar, one source | Broken at resale unless docs follow |
“For a Grade 23 or AMS 4928 order, the number on the certificate is only worth what the melt behind it is worth. Because we run our own VAR, the interstitial oxygen and nitrogen that decide fracture toughness are set on our floor, not inherited from a supplier we’d have to trust on faith.”
Titanium Bar Applications by Industry for Critical Engineering
Titanium bar and rod earns its cost where corrosion, strength-to-weight or both rule out steel. Here’s where each grade tends to land – and where we’re honest about scope.
Choosing by habit is the mistake here; a shop that defaults to Grade 5 for a seawater pump pays an alloy premium for corrosion that Grade 2 already delivers at 5/5 in seawater. TIALLOY machines, grinds, and heat treats to your drawing under an ISO 9001 quality system, while a stockist will ship standard bar and leave the finishing risk to you.
Chemical & petrochemical
Grade 2/7/12 for reactors, valves, fasteners and heat-exchanger internals in acids, chlorides and brines, the ~95% industrial-use grades.
Marine & desalination
Grade 2 and Grade 5 for seawater service, pump shafts and condenser hardware; corrosion factors rate Ti-6Al-4V 5/5 in seawater.
Commercial aerospace & industrial
Grade 5 and Grade 9 for structural and lightweight parts. Note: China-melt titanium isn’t DFARS-eligible for US defense, we serve commercial and international programs.
Medical-grade material
Grade 23 ELI bar to ASTM F136 as raw material for your qualified device supply chain, material conformance, not a finished-device clearance.
Grade 5 titanium bar delivers roughly three times the yield strength of commercially pure Grade 2 — letting a thinner, lighter section carry the same load.
Because titanium weighs about 56% of steel – around 44% lighter at a density of about 4.43 g/cm³ – the real economic case is the total cost of production, not the price per kilogram. When you weigh material against machine time and tooling, the right grade and form often outperform a less expensive alloy that resists the cutting tool.
Certifications & Quality Assurance
Trust in titanium procurement relies on one document more than any other: the mill test report. An EN 10204 3.1 certificate, certified by an inspection authority independent of production, ties every test result to the heat number the mill assigned during melt.
The traceability gap most specs miss
A procurement spec calling for a 3.1 certificate that quietly accepts a 2.2 has a compliance gap. And if the heat mark on the bar is scrubbed off or is illegible, the chain is broken; the certificate cannot be accepted without re-testing. As the actual melt source, TIALLOY stamps and certifies against our own heat numbers under an ISO 9001 system, so the paper never separates from the metal – whereas a stockist can only forward a certificate they did not produce. It’s the honest difference between owning a process and reselling one.
- Grade and condition: CP versus alloy, and annealed versus solution-treated-and-aged.
- Diameter, form and length: Round, flat, hex or hollow and any desired cut tolerance.
- Surface finish and processing: Ground, peeled, chamfered and tested to meet your specs.
- Quantity: Different mill economics for samples, small batches and bulk OEM orders.
- Incoterm and destination: FOB, CIF or DDP, including all applicable import duties upon arrival.
Titanium Bar Procurement Guide, Pricing Factors, MOQ & Global Export Logistics
Titanium bar pricing is driven by market forces, and any single price listed on a web page online is unlikely to be accurate, mixing retail per-piece, wholesale per-ton and scrap quotes. What truly affects your price is a defined set of factors, so we quote to your specific parameters rather than a misleading list price.
The hidden-cost pitfall: They want to focus just on per-kilo price, since the import duty, freight charges and cost of re-testing a rejected lot can create a big difference in your final landed cost. TIALLOY quotes in your grade, size, and Incoterm and provides a per-heat, ISO-certified cert package to bypass lengthy customs and QC hold ups – unlike an online price sheet that doesn’t consider it until you pay. It’s easier and more honest to compare landed cost rather than the “sticker” price of your metal.
Global Export & Market Dynamics
We supply most of our titanium products to international markets-Europe, South East Asia, the Middle East, Japan, South Korea, and South America-where FOB price ex-works of China can be directly competitive on its face. In the U.S., we make an effort to be fully transparent: as of early 2026, the import cost on Chinese titanium includes a tiered import duty plus a surcharge for applicable Section 301 actions, among the highest US tariffs on any major trading partner. Please verify the current rate for your Harmonized Tariff Schedule code at entry.
For minimum order quantity and lead time, we can tier orders from qualifying samples through small batches to large mill production runs and we can provide custom cut to length service for smaller quantities to avoid requiring full mill lengths. Let’s know your required grade, sizes, and approximate quantity to determine the applicable MOQ tier and lead time.
Buyer advisory: quote the landed cost, not the unit price
As any titanium supplier, please ask for landed cost instead of per-kilo cost-which for international means FOB + freight + local duties, and for US-bound material includes the above import duty stack. We’d rather have you judge us by grade capacity, melt quality, and the unmatched traceability that a stockist can’t provide, than on a public price that customs is likely to change on you anyway.

Frequently Asked Questions
Precision answers directly from the melt source. Navigate the matrix to clarify grade capabilities, traceability standards, and pricing factors.
A manufacturer. We melt, forge, and roll in-house, so the EN 10204 3.1 report is tied to our own heat numbers.
For reducing acids, chlorides, and crevice-corrosion service, Grade 7 (Ti-0.2Pd) leads; for hot acids and brines, Grade 12. Grade 2 covers general seawater and oxidising media. The Grade-to-Medium Matrix above maps all eight grades to their working environment.
ASTM B348 is the general commercial specification for titanium bars and billets across grades; AMS 4928 is the tighter Ti-6Al-4V (Grade 5) aerospace specification with defined mechanical minimums (about 130 ksi tensile, 120 ksi yield, annealed). We furnish Grade 5 bar to either, matched to your application.
Grade 23 is the extra-low-interstitial version of Grade 5, with oxygen held to a maximum of about 0.13% (vs 0.20% in Grade 5) for higher fracture toughness. It is used as fracture-critical and medical-grade material, as raw stock to ASTM F136 that a device maker qualifies within their own FDA-regulated supply chain.
By grade and condition, diameter and form, surface and processing, quantity tier, and Incoterm and destination duties, so there is no single titanium bar price per kg that fits every order. Because those factors move the number so much, and because titanium spot data online mixes retail, bulk, and scrap quotes, we quote against your exact parameters and give international and US buyers a full landed-cost picture rather than a headline figure that customs will change anyway.
Both. Orders are tiered from qualification samples through small batches to bulk runs, and we cut to length so a smaller order isn’t forced into standard mill lengths. Send your sizes and quantity for an MOQ and lead-time confirmation.
No. Titanium welding and TIG filler rod are consumables for joining, supplied as fine wire; titanium bar and rod stock is solid mill product for machining and fabrication. This page covers solid titanium rod and bar stock, not welding consumables.
Yes, an EN 10204 3.1 report with per-heat traceability, plus certification to the relevant ASTM/AMS standard. Because we are the melt source, the heat number on the bar and the results on the certificate come from the same floor.
