Product Detail
Product Introduction
Grade 12 Titanium Bar is supplied for corrosion-resistant fabrication and precision manufacturing. The final purchase definition must identify the exact material designation, governing specification and revision, dimensions, condition, tolerances, tests and documentation; trade-name or cross-standard equivalence is not assumed.
When should Grade 12 titanium bar be selected?
Selection answer: Grade 12 Ti-0.3Mo-0.8Ni is considered for machined or fabricated components requiring its combination of useful strength and corrosion performance in selected chemical, heat-transfer or elevated-temperature service.
Selection boundary: Do not treat Grade 12 as a universal upgrade over Grade 2, Grade 7 or a nickel alloy. Selection requires the actual medium, concentration, aeration, contaminants, temperature, crevice geometry, loads and fabrication route.
RFQ data to confirm: Send ASTM B348 revision, Grade 12 and UNS, section and length, condition, service chemistry and temperature, finished-part use, tolerances, inspection, certificates, quantity and destination for technical review.
Product Specifications
| Product | Grade 12 Titanium Bar | Grade | Titanium Grade 12 / UNS R53400 |
|---|---|---|---|
| Standard | ASTM B348/B348M covers annealed titanium and titanium-alloy bars and billets and identifies Grade 12 as UNS R53400, nominally Ti-0.3Mo-0.8Ni. State the exact specification revision, bar or billet form, dimensions and tolerances, condition, surface and straightness. Specifications for Grade 12 plate, tube, pipe or fittings have different product scopes and are not interchangeable. | Size & Form | Round bar, rod and cut blanks; diameter, length, straightness and machining allowance are confirmed by RFQ |
| Tolerance | Governing material standard or approved customer drawing | Supply Condition | Hot rolled, forged, annealed, peeled, pickled or ground as specified |
| Inspection | Verify heat identity, Grade 12 chemistry including molybdenum and nickel, tensile properties and applicable test orientation, dimensions, straightness, surface, marking, MTC and heat/lot traceability. Add ultrasonic examination, corrosion testing, PMI or third-party inspection only with an agreed method, coverage and acceptance criteria. | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Product naming consolidated | Grade 12 titanium bar and Grade 12 titanium rod describe the same solid bar product family here; plural and singular legacy pages are consolidated into this primary page. |
|---|---|
| Grade and specification boundary | Titanium Grade 12 / UNS R53400 bar is ordered to ASTM B348 or ASME SB348. Chemistry, condition, dimensions and test requirements must be stated on the purchase order. |
| Available supply forms | Round bar and cut-to-length rod, with diameter, length, straightness, surface, end preparation and machining allowance confirmed for the order. |
| Procurement focus | Provide diameter, length, quantity, condition, tolerance, surface, required inspection, MTC and heat traceability. Finished-component suitability remains subject to engineering review. |

FAQ
How does Grade 12 titanium bar differ from Grade 2?
Grade 12 contains nominal molybdenum and nickel and has different chemistry and mechanical requirements from commercially pure Grade 2. It is considered for selected corrosion and elevated-temperature duties, but suitability depends on the actual environment.
Is Grade 12 bar interchangeable with Grade 12 pipe or plate?
No. The alloy family may be the same, but product specifications, dimensions, tolerances, manufacturing routes and required tests differ. Order the correct product form and governing specification.
What information is needed for a Grade 12 bar quotation?
Provide ASTM B348/B348M revision, Grade 12 / UNS R53400, bar or billet form, diameter or section, length, condition, tolerance, straightness, surface, service medium and temperature, quantity, inspection, MTC and destination.
