1、Designation: A299/A299M 09Standard Specification forPressure Vessel Plates, Carbon Steel, Manganese-Silicon1This standard is issued under the fixed designation A299/A299M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of
2、 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.1. Scope*1.1 This specification2covers manganese-silicon carbonsteel plates for use in welded boilers and other pressure vessels.
3、1.2 Plates under this specification are produced in twogrades. The specified minimum yield strength decreases forthicknesses over 1 in. 25 mm.1.3 The maximum thickness of plates is limited only by thecapacity of the composition to meet the specified mechanicalproperty requirements; however, current
4、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 treatment or with stress relieving only, the additionalrequirements, including additional testing requirements and thereporting of add
5、itional test results, of Specification A20/A20Mapply.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; therefore, each system mustbe use
6、d independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.2.

8、ct specification shall con-form to Specification A20/A20M, which outlines the testingand retesting methods and procedures, permitted variations indimensions and mass, quality and repair of defects, marking,loading, and ordering information.3.2 In addition to the basic requirements of this specifica-
9、tion, certain supplementary requirements are available whereadditional 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 A20/A20M.3.3 Coils
10、 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 processing ofcoils int
11、o 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 with stress reliev
12、ing only, three test results are reported foreach qualifying coil. Additional requirements regarding plates from coilare described in Specification A20/A20M.3.4 If the requirements of this specification are in conflictwith the requirements of Specification A20/A20M, the require-ments of this specifi
13、cation shall prevail.4. Materials and Manufacture4.1 Steelmaking PracticeThe steel shall be killed andshall conform to the fine austenitic grain size requirement ofSpecification A20/A20M.5.
