1、Designation: A 299/A 299M 04Standard Specification forPressure Vessel Plates, Carbon Steel, Manganese-Silicon1This standard is issued under the fixed designation A 299/A 299M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the yea
2、r of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.NoteGrades A and B were added editorially to the entry for Carbon in Table 1 and the year date changed on Feb. 2, 2004.1.

3、ope*1.1 This specification2covers manganese-silicon carbonsteel plates for use in welded boilers and other pressure vessels.1.2 Plates under this specification are produced in twogrades. The specified minimum the yield strength decreases onthicknesses over 1 in. 25 mm.1.3 The maximum thickness of pl
4、ates is limited only by thecapacity of the composition to meet the specified mechanicalproperty requirements; however, current practice normallylimits the maximum thickness of plates furnished under thisspecification to 8 in. 200 mm.1.4 For plates produced from coil and furnished withoutheat treatme
5、nt or with stress relieving only, the additionalrequirements, including additional testing requirements and thereporting of additional test results, of Specification A 20/A 20M apply.1.5 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the tex
6、t, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.2. Referenced Documents2.1 ASTM Standards:3A 20/A
7、20M Specification for General Requirements forSteel Plates for Pressure Vessels3. General Requirements and Ordering Information3.1 Plates supplied to this product specification shall con-form to Specification A 20/A 20M, which outlines the testingand retesting methods and procedures, permissible var
8、iationsin dimensions and mass, quality 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 plates to this specification.3.3 In addition to the basic requirements of this s
9、pecifica-tion, certain supplementary requirements are available whereadditional control, testing, or examination is required to meetend use requirements.3.4 The purchaser is referred to the listed supplementaryrequirements in this specification and to the detailed require-ments in Specification A 20
10、/A 20M.3.5 Coils are excluded from qualification to this specifica-tion until they are processed into finished plates. Platesproduced from coil means plates that have been cut toindividual lengths from coil. The processor directly controls, oris responsible for, the operations involved in the proces
11、sing ofcoils into finished plates. Such operations include decoiling,leveling, cutting to length, testing, inspection, conditioning,heat treatment (if applicable), packaging, marking, loading forshipment, and certification.NOTE 1For plates produced from coil and furnished without heattreatment or wi
12、th stress relieving only, three test results are reported foreach qualifying coil. Additional requirements regarding plates from coilare described in Specification A 20/A 20M.3.6 If the requirements of this specification are in conflictwith the requirements of Specification A 20/A 20M, the re-quirem
13、ents of this specification shall prevail.4.
