ASTM A387-11 英文最新版

Designation: A387/A387M – 11 Used in USDOE-NE Standards Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium- Molybdenum1 This standard is issued under the fixed designation A387/A387M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope* 1.1 This specification2 covers chromium-molybdenum alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature service. 1.2 Plates are available under this specification in several grades having different alloy contents as follows: Nominal Nominal Chromium Molybde- num Grade Content, % Content, % 2 0.50 0.50 12 1.00 0.50 11 1.25 0.50 22, 22L 2.25 1.00 21, 21L 3.00 1.00 5 5.00 0.50 9 9.00 1.00 91 9.00 1.00 1.3 Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels as defined in the Tensile Requirements tables. Grades 21L and 22L are available only as Class 1. Grade 91 is available only as Class 2. NOTE 1—Grade 911, previously covered by this specification, is now covered by Specification A1017/A1017M. 1.4 The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. 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. Combining values from the two systems may result in nonconformance with this specifi- cation. 2.

The purchaser is referred to the listed supplementary requirements in this specification and to the detailed requirements in Specification A20/A20M. 3.3 If the requirements of this specification are in conflict with the requirements of Specification A20/A20M, the require- ments of this specification shall prevail. 4. Manufacture 4.1 Steelmaking Practice—The steel shall be killed. 5. Heat Treatment 5.1 Except for Grade 91, all plates shall be thermally treated either by annealing, normalizing- and -tempering, or, when permitted by the purchaser, accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. Minimum tempering temperatures shall be as follows: Grade Temperature, °F [°C] 2, 12, and 11 1150 [620] 22, 22L, 21, 21L, and 9 1250 [675] 5 1300 [705] 5.1.1 Grade 91 plates shall be thermally treated, either by normalizing-and-tempering or by accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. Grade 91 plates shall be austenitized at 1900 to 1975°F [1040 to 1080°C] and shall be tempered at 1350 to 1470°F [730 to 800°C]. 5.2 Grade 5, 9, 21, 21L, 22, 22L, and 91 plates ordered without the heat treatment required by 5.1 shall be furnished in either the stress-relieved or the annealed condition. 5.3 For plates ordered without the heat treatment required by 5.1, heat treatment of the plates to conform to 5.1 and to Table 2 or Table 3, as applicable, shall be the responsibility of the purchaser. 6.
