1.4 Forplates producedfromcoil andfurnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results of Specification A 20/A 20M apply. 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 systemmustbe usedindependentlyofthe other. Combining
values fromthe two systems may resultin nonconformance with the specification. 2. Referenced Documents 2.1 ASTM Standards: A 20/A 20M Specification for General Requirements for Steel Plates for Pressure Vessels A 435/A 435M Specification forStraight-BeamUltrasonic Examination of Steel Plates A 577/A 577M Specification for Ultrasonic Angle-Beam Examination of Steel Plates A 578/A 578M Specification forStraight-BeamUltrasonic Examination of Plain and Clad Steel Plates for Special Applications 3. General Requirements and Ordering Information 3.1 Plates supplied to this product specification shall conform to Specification A 20/A 20M, which outlines the testing and retesting methods and procedures, permissible variations in dimensions and mass, quality and repair of defects, marking, loading, and so forth. 3.2 SpecificationA 20/A 20M also establishes the rules forordering informationthatshouldbecompliedwithwhen purchasing plates to this specification. 3.3 In addition to the basic requirements ofthis specifi- cation, certain supplementary requirements are available where additional control, testing, or examination is required to meet end use requirements. 3.4 The purchaser is referred to the listed supplemen- tary requirements in this specification and to the detailed requirements in Specification A 20/A 20M.
3.5 Coils are excluded from qualification to this speci- fication until they are processed into finished plates. Plates produced from coil means plates that have been cut to individual lengths from coil. The processor directly con- trols, or is responsible for, the operations involved in the processing of coils into finished plates. Such operations include decoiling, leveling, cutting to length, testing, inspection, conditioning, heat treatment (if applicable), packaging, marking, loading for shipment, and certifi- cation. NOTE 1: For plates produced from coil and furnished without heat treatment or with stress relieving only, three test results are reported for each qualifying coil. Additional requirements regarding plate produced from coil are described in Specification A 20/A 20M. 3.6 If the requirements of this specification are in con- flict with the requirements of Specification A 20/A 20M, the requirements of this specification shall prevail. 4. Materials and Manufacture 4.1 Steelmaking Practice—The steel shall be killed and shall conform to the fine austenitic grain size requirement of Specification A 20/A 20M. 5. Heat Treatment 5.1 Plates 1.50 in. [40 mm] and under in thickness are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.
5.2 Plates over 1.50 in. [40 mm] in thickness shall be normalized. 5.3 When notch-toughness tests are required on plates 1 1 ⁄ 2 in. [40 mm] and under in thickness, the plates shall be normalized unless otherwise specified by the purchaser. 5.4 If approved by the purchaser, cooling rates faster than those obtained by cooling in air are permissible for improvement of the toughness, provided the plates are subsequently tempered in the temperature range 1100 to 1300°F [595 to 705°C]. 6. Chemical Composition 6.1 The steel shall conform to the chemical require- ments given in Table 1 unless otherwise modified in accor- dance with Supplementary Requirement S17, Vacuum Carbon-Deoxidized Steel, in Specification A 20/A 20M. 7. Mechanical Properties 7.1 Tension Test—The plates, as represented by the tension test specimens, shall conform to the requirements given in Table 2.
