Designation:A786/A786M15Standard Specification forHot-Rolled Carbon,Low-Alloy,High-Strength Low-Alloy,andAlloy Steel Floor Plates1This standard is issued under the fixed designation A786/A786M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript 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 carbon,low-alloy,high-strength low-alloy,and alloy steel hot-rolled floor plates forflooring,stairways,transportation equipment,and generalstructural purposes.While it is generally provided in theas-rolled condition,floor plate also may be provided in theheat-treated condition,depending on the material specification.Rolled floor plates have raised figures at regular intervals onone surface of the plate.1.2 Floor plate is available in dimensions that meet theclassification size limits for sheet,heavy thickness sheet coil,or plate.Maximum thickness for product delivered under thisspecification is 1 in.25 mm.1.3 When the steel is to be welded,it is presupposed that awelding procedure suitable for the grade of steel and intendeduse or service will be utilized.See Appendix X3 of Specifica-tion A6/A6M for information on weldability.1.4 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.The values stated ineach system are not exact equivalents;therefore,each system isto be used independently of the other,without combiningvalues.2.Referenced Documents2.1 ASTM Standards:2A6/A6M Specification for General Requirements for RolledStructural Steel Bars,Plates,Shapes,and Sheet PilingA36/A36M Specification for Carbon Structural SteelA131/A131M Specification for Structural Steel for ShipsA242/A242M Specification for High-Strength Low-AlloyStructural SteelA514/A514M SpecificationforHigh-Yield-Strength,Quenched and Tempered Alloy Steel Plate,Suitable forWeldingA568/A568M Specification for Steel,Sheet,Carbon,Structural,and High-Strength,Low-Alloy,Hot-Rolled andCold-Rolled,General Requirements forA572/A572M Specification for High-Strength Low-AlloyColumbium-Vanadium Structural SteelA573/A573M Specification for Structural Carbon SteelPlates of Improved ToughnessA588/A588M Specification for High-Strength Low-AlloyStructural Steel,up to 50 ksi 345 MPa Minimum YieldPoint,with Atmospheric Corrosion ResistanceA606/A606M Specification for Steel,Sheet and Strip,High-Strength,Low-Alloy,Hot-Rolled and Cold-Rolled,withImproved Atmospheric Corrosion ResistanceA635/A635M Specification for Steel,Sheet and Strip,Heavy-Thickness Coils,Hot-Rolled,Alloy,Carbon,Structural,High-Strength Low-Alloy,and High-StrengthLow-Alloy with Improved Formability,General Require-ments forA659/A659M Specification for Commercial Steel(CS),Sheet and Strip,Carbon(0.16 Maximum to 0.25 Maxi-mum Percent),Hot-RolledA709/A709M Specification for Structural Steel for BridgesA829/A829M Specification for Alloy Structural Steel PlatesA830/A830M Specification for Plates,Carbon Steel,Struc-tural Quality,Furnished to Chemical Composition Re-quirementsA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and FerroalloysA1011/A1011M Specification for Steel,Sheet and Strip,Hot-Rolled,Carbon,Structural,High-Strength Low-Alloy,High-StrengthLow-AlloywithImprovedFormability,and Ultra-High StrengthA1018/A1018M Specification for Steel,Sheet and Strip,Heavy-ThicknessCoils,Hot-Rolled,Carbon,Commercial,Drawing,Structural,High-Strength Low-Alloy,High-StrengthLow-AlloywithImprovedFormability,and Ultra-High Strength1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.02 on Structural Steel for Bridges,Buildings,Rolling Stock and Ships.Current edition approved Nov.1,2015.Published December 2015.Originallyapproved in 1981.Last previous edition approved in 2009 as A786/A786M 05(2009).DOI:10.1520/A0786_A0786M-15.2For 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 3.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,refer to Terminology A941.4.Surface Pattern4.1 Individual floor plate patterns are unique to each manu-facturer and are not identical in dimension or appearance topatterns manufactured by other manufacturers,although theremay be a close resemblance.Typical patterns are shown in Fig.1.Manufacturers generally produce only one of the patternsshown.4.
