Titanium Product-Form & Standard Crosswalk
Compare the product-form boundary before using a grade, UNS number, or certification term in a request. This guide summarizes public scope statements; the controlled standard and accepted order specification remain decisive.
| Request category | Public standard boundary | Grade evidence | RFQ action |
|---|---|---|---|
| Condenser / heat-exchanger tube | ASTM B338-17(2026): tube made without a longitudinal weld and welded tube. | Public scope lists 28 grades, including 1, 2, 7, 9 and 12; it does not list 5 or 23. | State service, OD, wall, route, tests and revision. |
| Industrial pipe without a longitudinal weld | ASTM B861-24: titanium and titanium-alloy pipe made without a longitudinal weld. | Public scope includes Grade 23 as UNS R56407. | Confirm corrosion or elevated-temperature service and pipe dimensions. |
| Industrial welded pipe | ASTM B862-23: titanium and titanium-alloy welded pipe. | Use the current controlled standard for the accepted grade list. | Define weld route, inspection and pressure-design basis. |
| Surgical-implant wrought material | ASTM F136-26: Ti-6Al-4V ELI wrought material. | Public scope lists strip, sheet, plate, bar, forging bar and wire, not tube or pipe. | Do not use F136 alone as tube or pipe evidence. |
Boundary: The tool does not approve a product, certify an alloy, or determine medical, aerospace, pressure-code, or customer qualification. It identifies the evidence that must accompany the RFQ.
