Composition & Mechanical Properties
| Grade / UNS | Zr + Hf % | Hf % | Fe + Cr % | H % | N % | C % | O % |
|---|---|---|---|---|---|---|---|
| Zirconium 702 R60702 | ≥99.2 | ≤4.5 | ≤0.20 | ≤0.005 | ≤0.025 | ≤0.050 | ≤0.16 |
Composition values are mass percentages. ≤ indicates a maximum; ≥ indicates a minimum.
| Grade / UNS | Product form / condition | Tensile min (MPa) | Yield min (MPa) | Elongation min (%) | Hardness | Bend radius |
|---|---|---|---|---|---|---|
| Zirconium 702 R60702 | Annealed · Strip / sheet / plate | 380 | 205 | 16 | — | 5T |
- Elongation uses a 2 in. / 50 mm gauge length.
- Strip and sheet bend testing uses a 105° bend and a mandrel radius of 5T, where T is specimen thickness.
- Hydrogen and nitrogen are determined on the finished product.
From material form
to gasket component.
Review the listed material grade and its delivery condition when selecting winding strip or ring stock for a specified gasket design.
Material standards and gasket standards serve different purposes.
ASTM B551 addresses the material forms identified on this page. Finished metallic gasket requirements are addressed separately by the applicable gasket standard.
