ASME A515 pdf free download SPECIFICATION FOR PRESSURE VESSEL PLATES, CARBON STEEL, FOR INTERMEDIATE- AND HIGHER- TEMPERATURE SERVICE
1. Scope
1.1 This specification covers carbon-silicon steel plates primarily for intermediate- and higher-temperature service in welded boilers and other pressure vessels.
1.2 Plates under this specification are available in three grades having different strength levels as follows:
1.3 The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current prac- tice normally limits the maximum thickness of plates fur- nished under this specification as follows:
1.4 Forplates producedfromcoil andfurnishedwithout heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting ofadditional test results, ofSpecification 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 result in nonconformance with the specification.

2.1 ASTM Standards: A 20/A 20M Specification for General Requirements for Steel Plates for Pressure Vessels 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 informationthatshouldbe compliedwithwhen 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.
