Designation: A615/A615M - 20 Standard Specification for Deformed and Plain Carbon-Steel Bars for ConcreteReinforcement1'1. Scope*1.1This specification covers deformed and plain carbon-steel bars in cut lengths and coils for concretc reinforcement.Annex A2 of this specification covers deformed bars for use forother applications. Steel bars containing alloy additions.suchas with the Association for Iron and Steel 'Technology and theSociety of Automotive Engincers series of alloy steels，arepermitted if the resulting product meets all the other require-ments of this specification.The standard sizes and dimensionsof deformed bars and their number designations are given inTable 1.1.2 Unless specified for use for other applications in AnnexA2. bars are of four minimum yield strength levels: namely.40 oo0 psi [280 MPa]. 60 o0o psi [420 MPa]. 80 OO0 psi [550MPa]. and 10o o00o psi [690 MPa].designated as Grade 40[280], Grade 60[420]. Grade 80 [550], and Grade 100[690].respectively.NonE 1—Grade 10O[690]reinforcing bars were introcluced in thisspocification in 2015.In contrast to the lower grades,which have rutios ofspecified tensile strength to specified yield strength than range from
