Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum-Tungsten
|Publication Date:||10 March 2001|
|ICS Code (Steels for pressure purposes):||77.140.30|
1.1 This specification covers Chromium-Molybdenum-
1.2 Plates are available under this specification in three grades having different alloy contents as follows:
|Grade||Nominal Chromium Content, %||Nominal Molybdenum Content, %||Nominal Tungsten Content, %|
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 inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
