ASME SA516:2021 pdf free download SPECIFICATION FOR PRESSURE VESSEL PLATES, CARBON STEEL, FOR MODERATE- AND LOWER-TEMPERATURE SERVICE
1.Scope
1.1 This specification covers carbon steel plates intendedprimarily for service in welded pressure vessels where im-proved notch toughness is important.
1.2 Plates under this specification are available in fourgrades having different strength levels as follows:
Grade U.s.[SI]
Tensile Strength,
ksi [MPa]
55[380]
55-75[380-515]
6o[415j
6o-80 [415-550]
65[450]
65-85[450-585]
7o[485j
7o-9o [485-620]
1.3 The maximum thickness of plates is limited only by thecapacity of the composition to meet the specified mechanicalproperty requirements.
1.4 For plates produced from coil and furnished withoutheat treatment or with stress relieving only,the additionalrequirements, including additional testing requirements and thereporting of additional test results of Specification A20/A20Mapply.
1.5 The values stated in either inch-pound units or Sl unitsare to be regarded separately as standard. Within the text, theSl units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.
1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards，Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.

3. General Requirements and Ordering Information3.1 Material supplied to this product specification shallconform 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 Inaddition to the basic requirements of thisspecification, certain supplementary requirements are availablewhere additional control, testing, or examination is required tomeet end use requirements. The purchaser is referred to thelisted supplementary requirements in this specification and tothe detailed requirements in Specification A20/A20M.
3.3 If the requirements of this specification are in conflictwith the requirements of Specification 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. 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 processing 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.
