| Monel 400 hot-rolled sheet | 0.018”≤T≤0.250”[0.46mm≤T≤6.4 mm] |
| Monel 400 cold-rolled sheet | 0.018”≤T≤0.250”[0.46mm≤T≤6.4 mm] |
| Monel 400 cold-rolled strip | 0.005”≤T≤0.250”[0.46mm≤T≤6.4 mm] |
*Materials with thickness 4.8 mm≤T≤6.4 mm may be furnished as sheet or plate.
*Materials with width W＜48″[1219 mm] shall be furnished as sheet or strip.
