1、Designation: A299/A299M 09 (Reapproved 2014)Standard 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 rev
2、ision, 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.1. Scope1.1 This specification2covers manganese-silicon carbonsteel plates for use in welded boilers and other
3、pressure vessels.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;
4、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 treatment or with stress relieving only, the additionalrequirements, including additional testing requirements and th
5、ereporting of additional 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
6、system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.2.

The purchaser is referred to thelisted supplementary requirements in this specification and tothe detailed requirements in Specification A20
10、/A20M.3.3 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 process
11、ing 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 wit
12、h stress relieving 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
13、of this specification shall prevail.4.
