3. General Requirements and Ordering Information 3.1 Material supplied to this product specification shall conform to Specification A20/A20M, which outlines the test- ing and retesting methods and procedures, permissible varia- tions in dimensions and mass, quality and repair of defects, marking, loading, and ordering information. 3.2 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 requirements. The purchaser is referred to the listed supplementary requirements in this specification and to the detailed requirements in Specification A20/A20M. 3.3 If the requirements of this specification are in conflict with the requirements ofSpecification A20/A20M, the require- ments of this specification shall prevail. 3.4 Coils are excluded from qualification to this specifica- tion 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 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.
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 A20/A20M.
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 improve- ment 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 requirements given in Table 1 unless otherwise modified in accordance with Supplementary Requirement S17, Vacuum Carbon-Deoxidized Steel, in Specification A20/A20M.
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.ASME SA-516 pdf download.
