Designation:A50616Standard Specification forAlloy and Structural Alloy Steel,Sheet and Strip,Hot-Rolledand Cold-Rolled1This standard is issued under the fixed designation A506;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers hot-rolled and cold-rolledalloy and structural alloy-steel sheet and strip.Alloy steel isfurnished to chemical composition requirements and is in-tended primarily for general or miscellaneous use wherebending and moderate forming is a requirement.Structuralalloy steel is furnished to chemical composition requirementsand to specific mechanical property requirements which mayinclude tension tests,hardness tests,or other commonlyaccepted mechanical tests.1.2 If material of a higher degree of uniformity of internalsoundness and freedom from surface imperfections is required,reference should be made to Specification A507.1.3 Alloy and structural alloy-steel sheet and strip are notproduced to internal cleanliness requirements.Normally sur-face imperfections are not objectionable,and a good finish isnot a prime requirement.1.4 The formability of structural alloy steel decreases withincreasing yield strength or hardness.Therefore,product de-sign in relation to the mechanical properties of the grade usedmust be considered.1.5 The material covered by this specification may befurnished in several conditions:heat treatments,surfaceconditions,and edges,as specified herein,in coils or cutlengths.1.6 The values stated in inch-pound units are to be regardedas the standard.SI units are provided for information only.2.Referenced Documents2.1 ASTM Standards:2A505 Specification for Steel,Sheet and Strip,Alloy,Hot-Rolled and Cold-Rolled,General Requirements forA507 Specification for DrawingAlloy Steel,Sheet and Strip,Hot-Rolled and Cold-Rolled3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 alloy steelalloy-steel sheet and strip furnished tochemical composition requirements and intended for general ormiscellaneous applications where normal surface imperfec-tions are not objectionable and a good finish is not the primerequirement.3.1.2 SAESociety of Automotive Engineers.3.1.3 standard steelssteel chemical compositions definedas“standard”by SAE,shown in Table 1.3.1.4 steels other than standardsteel chemical composi-tions other than those defined as“standard,”and furnished tothe composition limits shown in Table 2.3.1.5 structural alloy steelalloy-steel sheet and strip meet-ing the requirements of regular quality and also produced tospecific mechanical property requirements.4.General Requirements and Ordering Information4.1 Material supplied to this specification shall conform toSpecification A505,which includes the general requirementsand establishes the rules for the ordering information thatshould be complied with when purchasing material to thisspecification.4.2 In addition to the ordering information required bySpecification A505,the following shall also be included:4.2.1 Mechanical properties required for structural quality,when applicable,4.2.2 Surface finish,if other than standard(see 8.1),and4.2.3 Surface treatment,if other than standard(see 8.2).5.Materials and Manufacture5.1 RollingThe material shall be furnished either hot-rolled or cold-rolled,as specified on the order.5.2 Heat Treatment:1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.19 on Steel Sheet and Strip.Current edition approved May 1,2016.Published May 2016.Originallyapproved in 1964.Last previous edition approved in 2012 as A506 12.DOI:10.1520/A0506-16.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2.1 Hot-RolledHot-rolled material shall be furnished inone of the following conditions,as specified on the order:5.2.1.1 As-rolled,5.2.1.2 Annealed,5.2.1.3 Normalized,or5.2.1.4 Normalized-and-tempered.5.2.2 Cold-RolledCold-rolled material shall be fully an-nealed after cold-rolling.(Temper,skin,or roller leveling forthe control of flatness,which does not significantly affect theproperties,may be performed after annealing.)6.Chemical Requirements6.1 The heat analysis shall conform to the requirements forthe grade specified on the order.6.1.1 Alloy SteelThe grade shall be specified in accor-dan
