1.1This specification covers Chromium-Molybdenum-Tungsten alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature service.
1.2Plates are available under this specification in grades having different alloy contents as follows:
| Grade | Nominal | Nominal | Nominal |
| 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 |
1.3The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
1.4The 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.
1.5The 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.
