Product Detail
Product Introduction
Titanium Grade 7 coil combines commercially pure titanium characteristics with a controlled palladium addition for improved resistance in demanding corrosion environments. The order must define thickness, width, coil inside and outside diameter, coil weight, edge condition, flatness or camber requirements, surface condition, inspection and documentation.
Product Specifications
| Product | Titanium Grade 7 Coil | Grade | Titanium Grade 7 / UNS R52400 |
|---|---|---|---|
| Standard | ASTM B265 / ASME SB265 applies to titanium strip, sheet and plate when expressly invoked. Specify Grade 7 / UNS R52400, the required edition, dimensions, condition, tolerances and supplementary requirements on the purchase order. | Size & Form | Thickness, width, coil inside/outside diameter, maximum coil weight and slit or mill-edge condition are confirmed by RFQ |
| Tolerance | ASTM B265 / ASME SB265 or tighter order-defined thickness, width, camber and edge requirements | Supply Condition | Annealed coil or precision slit strip with pickled, descaled or order-specific surface condition |
| Inspection | MTC and heat/lot identity review, chemistry and tensile results, thickness and width, coil dimensions and weight, edge condition, surface examination and supplementary testing when agreed. | Documents | MTC, heat/lot traceability and agreed inspection reports |

FAQ
What is the difference between Grade 7 and Grade 2 titanium coil?
Grade 7 is based on commercially pure titanium with a specified palladium addition. The improvement is relevant to selected reducing-acid and crevice-corrosion conditions, but the complete environment and fabrication design still require engineering review.
Which standard applies to Grade 7 titanium coil?
ASTM B265 / ASME SB265 covers Grade 7 strip, sheet and plate when expressly ordered. The purchase order should state the required edition, form, dimensions, condition, tolerances and supplementary requirements.
What information is needed for quotation?
Provide Grade 7 / UNS R52400, thickness, width, coil ID and OD, maximum coil weight, edge condition, surface, quantity, application, tests, documents and destination.
