Composition & Mechanical Properties
| Grade / UNS | Ni % | Cu % | Fe % | Mn % | C % | Si % | S % |
|---|---|---|---|---|---|---|---|
| Monel 400 N04400 | ≥63.0 | 28.0–34.0 | ≤2.5 | ≤2.0 | ≤0.30 | ≤0.50 | ≤0.024 |
Composition values are mass percentages. ≤ indicates a maximum; ≥ indicates a minimum.
| Grade / UNS | Product form / condition | Tensile min / range (MPa) | Yield min (MPa) | Elongation min (%) | Hardness |

| Monel 400 N04400 | Hot-rolled plate · As-rolled | 515 | 275 | 25 | — |
| Monel 400 N04400 | Cold-rolled sheet / strip · Annealed | 485–585 | 195 | 35 | — |
| Monel 400 N04400 | Cold-rolled strip · Skin hard | — | — | — | 68–73 HRB |
| Monel 400 N04400 | Cold-rolled sheet / strip · Quarter-hard | — | — | — | 73–83 HRB |
| Monel 400 N04400 | Cold-rolled sheet / strip · Half-hard | — | — | — | 82–90 HRB |
| Monel 400 N04400 | Cold-rolled strip · Three-quarter-hard | — | — | — | 89–94 HRB |
| Monel 400 N04400 | Cold-rolled sheet / strip · Hard | 690 | 620 | 2 | — |
| Monel 400 N04400 | Cold-rolled strip · Spring temper | — | — | — | ≥98 HRB |
- Yield requirements exclude material thinner than 0.020 in. (0.51 mm).
- For cold-rolled strip, tensile and elongation requirements exclude thicknesses below 0.010 in. (0.25 mm).
- Deep-drawing and spinning-quality sheet and strip have separate grain-size and hardness requirements; these tensile rows do not apply to those qualities.
- Nickel is determined by difference. Elongation uses a 2 in. / 50 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 B127 addresses the material forms identified on this page. Finished metallic gasket requirements are addressed separately by the applicable gasket standard.
