3. General Requirements and Ordering Inforniation
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 Specification A 20/A 20M also establishes the rules for ordering information that should he complied with when purchasing plates to this specification.
3.3 In addition to the basic requirements of this specification, certain supplementary requirements are available where additional control, testing, or examination is required to meet end use rcquiremcnts.
3.4 The purchaser is referred to the listed supplementary requirements in this specification and to the detailed requirements in Specification A 20/A 20M.
3.5 Coils are excluded from qualification to this specification until they are processed into finished plates. Plates produced from coil means plates that have been ciii to individual lengths from coil. The processor directly controls, 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 certification.
NOTE 1: For plates produced from coil and furnished without heattreatment or with stress relieving only, three test results are reported foreach qualifying coil. Additional requirements regarding plate producedfrom 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 andmade to a coarse austenitic grain size practice.
5.Heat Treatment
5.1 Plates 2 in.[50 mm] and under in thickness arenormally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.5.2Plates over 2 in. [50 mm] in thickness shall benormalized.
6.Chemical Composition
6.1The steel shall conform to the chemical require-ments given in Table 1 unless otherwise modified in accor-dance with Supplementary Requirement S17, VacuumCarbon-Deoxidized Steel, in Specification A 20/A 20M.
7.Mechanical Properties
7.1Tension Test-The plates，as represented by thetension test specimens, shall conform to the requirementsgiven in Table 2.
