| Status: | inactive |
| Page Count: | 3 |
| ICS Code (Steels for pressure purposes): | 77.140.30 |
scope:
1.1 This specification covers Chromium-Molybdenum-
1.2 Plates are available under this specification in grades having different alloy contents as follows:
| Grade | Nominal Chromium Content, % | Nominal Molybdenum Content, % | Nominal Tungsten Content, % |
| 23 | 2.25 | 0.20 | 1.60 |
| 911 | 9.00 | 1.00 | 1.00 |
| 92 | 9.00 | 0.45 | 1.75 |
| 122 | 12.00 | 0.40 | 2.00 |
1.3 The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
1.4 The specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished to inch-pound units.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
