1、Designation: A 1017/A 1017M 07Standard Specification forPressure Vessel Plates, Alloy Steel, Chromium-Molybdenum-Tungsten1This standard is issued under the fixed designation A 1017/A 1017M; the number immediately following the designation indicates theyear of original adoption or, in the case of rev
2、ision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers Chromium-Molybdenum-Tungsten alloy steel plates intended primarily for
3、weldedboilers and pressure vessels designed for elevated temperatureservice.1.2 Plates are available under this specification in threegrades having different alloy contents as follows:GradeNominalChromiumContent, %NominalMolybdenumContent, %NominalTungstenContent, %23 2.25 0.20 1.60911 9.00 1.00 1.0
4、0122 12.00 0.40 2.001.3 The maximum thickness of plates is limited only by thecapacity of the composition to meet the specified mechanicalproperty requirements.1.4 The specification is expressed in both inch-pound unitsand in SI units. However, unless the order specifies theapplicable “M” specificat
5、ion designation (SI units), the mate-rial shall be furnished to inch-pound units.1.5 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; there
6、fore, each system mustbe used independently of the other.2.

Such requirementsoutline the testing and retesting methods and procedures,permissible variations in dimensions and weight mass, qual-it
8、y and repair of defects, marking, loading, and so forth.3.2 Specification A 20/A 20M also establishes the rules forthe ordering information that should be complied with whenpurchasing material to this specification.3.3 In addition to the basic requirements of this specifica-tion, certain supplementa
9、ry requirements are available whenadditional control, testing, or examination is required to meetend use requirements. The purchaser is referred to the listedsupplementary requirements in this specification and to thedetailed requirements in Specification A 20/A 20M.3.4 If the requirements of this s
10、pecification are in conflictwith the requirements of Specification A 20/A 20M, the re-quirements of this specification shall prevail.4. Materials and Manufacture4.1 Steelmaking PracticeThe steel shall be killed.5. Heat Treatment5.1 Except as allowed by 5.2 and 5.3, all plates shall benormalized at 1
11、900 to 1975F 1040 to 1080C. Plates forGrades 23 and 122 shall be tempered at 1350 to 1470F 730to 800C. Grade 911 plates shall be tempered at 1365 to1435F 740 to 780C.5.2 If permitted by the purchaser, plates for Grades 23 and122 may be austenitized at 1900 to 1975F 1040 to 1080C,subjected to acceler
12、ated cooling from the austenitizing tem-perature by air blasting or liquid quenching, and then temperedat 1350 to 1470F 730 to 800C.5.3 Plates ordered without the heat treatment required byeither 5.1 or 5.2 shall be furnished in either the stress-relievedor annealed condition, and the purchaser shal
13、l be responsiblefor the heat treatment of such plates to conform to either 5.1 or5.2.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.11 on Steel Plates for Boilers and Pressure Vessels
