Composition & Mechanical Properties
| Grade / UNS | Ni % | Cr % | Mo % | Fe % | W % | Co % | C % | Si % | Mn % | V % | P % | S % |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Hastelloy C-276 N10276 | Remainder | 14.5–16.5 | 15.0–17.0 | 4.0–7.0 | 3.0–4.5 | ≤2.5 | ≤0.010 | ≤0.080 | ≤1.0 | ≤0.35 | ≤0.040 | ≤0.030 |
| Hastelloy C-22 N06022 | Remainder | 20.0–22.5 | 12.5–14.5 | 2.0–6.0 | 2.5–3.5 | ≤2.5 | ≤0.015 | ≤0.080 | ≤0.50 | ≤0.35 | ≤0.020 | ≤0.020 |
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 |
|---|---|---|---|---|---|
| Hastelloy C-276 N10276 | Solution annealed · Plate / sheet / strip | 690 | 283 | 40 | 100 HRB (informative) |
| Hastelloy C-22 N06022 | Solution annealed · Plate / sheet / strip | 690 | 310 | 45 | 100 HRB (informative) |
- Hardness is supplied for information only in this edition and is not an acceptance or rejection criterion.
- Nickel is determined by difference.
- The tensile requirements apply at room temperature. Elongation uses a 2 in. / 50.8 mm or 4D gauge length.
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 B575 addresses the material forms identified on this page. Finished metallic gasket requirements are addressed separately by the applicable gasket standard.
