Product Detail
Product Introduction
Grade 2 Titanium Circular Blank is a cut-to-shape intermediate product, not a forging or a finished machined disc. The order should identify the certified base-plate grade and specification, finished or rough diameter, thickness, edge condition, flatness, surface, machining allowance, quantity, cutting route and inspection requirements.
Product Specifications
| Product | Grade 2 Titanium Circular Blank | Grade | Titanium Grade 2 / UNS R50400 |
|---|---|---|---|
| Standard | ASTM B265/B265M covers titanium and titanium-alloy strip, sheet and plate, including Grade 2 and Grade 5. It certifies the source plate when invoked; the circular diameter, cut edge and blank-specific tolerances must be defined by the order or approved drawing. | Size & Form | Diameter and thickness by RFQ; rough-cut, finish-cut or machining-allowance dimensions according to the approved drawing |
| Tolerance | Order-defined diameter, roundness, thickness, flatness and edge tolerance; base-plate tolerances follow the invoked material specification | Supply Condition | Waterjet, saw, laser, plasma or machined profile as technically agreed; surface and cut-edge protection for shipment |
| Inspection | Review base-plate MTC and heat identity, thickness, blank diameter, roundness, flatness, surface and cut edge. Add dye penetrant, ultrasonic examination, positive material identification or an edge-removal witness when required by the finished component quality plan. | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Grade 2 selection | Grade 2 / UNS R50400 circular blanks prioritize commercially pure titanium corrosion resistance, ductility and weldability for process, marine and fabricated components. |
|---|---|
| Service data | Provide medium, concentration, temperature, contaminants, crevices and galvanic contacts; confirm finished-part stresses and fabrication route. |
| Cut-edge processing | Define cutting method, heat-affected-zone restrictions, edge cleanup and machining allowance appropriate to Grade 2 forming, welding or machining. |
| Certification | Request ASTM B265 Grade 2 parent-plate MTC, heat mapping, blank dimensions, surface and edge inspection and marking transfer. |

FAQ
Is a circular plate blank the same as a forged disc?
No. A circular blank is cut from rolled plate, while a forged disc is produced through a forging route. Grain flow, available thickness, inspection and design qualification can differ.
Does ASTM B265 define the blank diameter tolerance?
ASTM B265/B265M governs the source plate when invoked. Blank diameter, roundness, cut-edge condition and machining allowance should be stated on the order or drawing.
What allowance should be added for machining?
Allowance depends on diameter, thickness, cutting route, edge taper, flatness and the finished-part tolerance. Provide the final drawing so an appropriate rough-blank size can be agreed.
