Product Detail
Product Introduction
Grade 2 Titanium Hex Bar is purchased as near-shape machining stock. Define the alloy grade, governing specification and revision, shape and dimensions, condition, surface, length, tolerances, quantity, end use, inspection and documentation. The finished component design determines whether hexagonal, flat or round stock offers the best material yield and machining route.
Product Specifications
| Product | Grade 2 Titanium Hex Bar | Grade | Titanium Grade 2 / UNS R50400 |
|---|---|---|---|
| Standard | ASTM B348/B348M covers titanium and titanium-alloy bars and billets, including Grade 2 and Grade 5. State the required revision and confirm that the ordered shape and dimensions fall within the supplier and specification scope; drawing tolerances and supplementary inspection must be listed separately. | Size & Form | Across-flats size, corner geometry, length and straightness by RFQ |
| Tolerance | ASTM B348/B348M, approved drawing or order-defined dimensional, straightness, flatness, corner and edge tolerances | Supply Condition | Annealed or order-specific condition; descaled, pickled, ground, machined or protected surface as applicable |
| Inspection | MTC and heat/lot identity, chemistry and tensile results, across-flats or thickness and width, length, straightness or flatness, corner or edge condition, surface examination and any agreed ultrasonic or supplementary tests. | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| How hex bar is dimensioned | Specify the nominal across-flats dimension, permissible variation across flats, corner condition or corner radius, twist, straightness and cut length. A round-bar diameter is not an interchangeable hex-bar dimension. |
|---|---|
| Why buyers select hex stock | Six-sided stock can reduce machining removal for hexagonal fasteners, valve components, instrument bodies and wrench-driven parts. Confirm whether the finished corners remain functional or are machining allowance only. |
| Manufacturing route to confirm | Rolled, drawn, forged or machined-from-round routes can produce different corner geometry, surface condition and economic quantity. The accepted route should be recorded on the quotation or purchase order. |
| Inspection focus | Measure across flats at agreed locations, inspect twist and straightness over the ordered length, review corner damage and surface discontinuities, and retain heat/lot identity through cutting and packing. |
| Grade 2 material behavior | Grade 2 / UNS R50400 is commercially pure titanium selected for corrosion resistance, ductility and weldability rather than the substantially higher strength of Ti-6Al-4V Grade 5. |
| Grade 2 service review | Provide process medium, concentration, temperature, contaminants, aeration, crevices and galvanic interfaces. Grade name alone does not establish corrosion suitability. |
| Grade 2 application fit | Common review areas include chemical-process, marine, desalination and corrosion-resistant valve or instrument parts where the design strength requirement fits Grade 2. |

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

Hex fasteners, nuts and wrench-driven machined parts
Material grade, dimensions, condition and inspection must be matched to the application requirements.

Valve stems, instrument bodies and fluid-control components
Material grade, dimensions, condition and inspection must be matched to the application requirements.

Marine and chemical-process components requiring reduced machining stock
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Is hex bar ordered by diameter?
No. Hexagonal bar is normally ordered by its across-flats dimension. Also state corner condition, length, twist, straightness and dimensional tolerance.
Why use titanium hex bar instead of round bar?
Hex stock can reduce machining waste and cycle time when the finished component retains flats. Round bar may be more economical when the finished geometry is primarily circular.
Can ASTM B348 alone define every hex-bar tolerance?
No. State the invoked revision and confirm shape coverage, then add order-specific across-flats, corner, twist, straightness, surface and cut-length requirements.
