1、Designation:A1035/A1035M16bStandard Specification forDeformed and Plain,Low-Carbon,Chromium,Steel Bars forConcrete Reinforcement1This standard is issued under the fixed designation A1035/A1035M;the number immediately following the designation indicates theyear of original adoption or,in the case of
2、revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers deformed and plain low-carbon,chromium,steel bars,in cut lengths and coils
3、forconcrete reinforcement.These bars are furnished in three alloytypes depending on the chromium range content.The standardsizes and dimensions of deformed bars and their numberdesignations are given in Table 1.21.2 Bars are of two minimum yield strength levels asdefined in 9.2:namely,100 000 psi 69
4、0 MPa,and 120 000 psi830 MPa designated as Grade 100 690 and Grade 120830,respectively.1.3 Barsarefurnishedtothreedifferentchemicalcompositions,designated as Alloy Type CL,CM,and CS.Chemical compositions are shown in Table 2.1.4 Plain bars,in sizes up to and including 2.25 in.57.2mm 212in.63.5 mm in
5、 diameter in coils and cut lengths,when ordered shall be furnished under this specification inGrade 100 690 and Grade 120 830.For ductility properties(elongation and bending),test provisions of the nearest smallernominal diameter deformed bar size shall apply.Requirementsproviding for deformations a
6、nd marking shall not be appli-cable.NOTE1Welding of the material in this specification should beapproached with caution since no specific provisions have been includedto enhance its weldability.When this steel is to be welded,a weldingprocedure suitable for the chemical composition and intended use
7、orservice should be used.NOTE2Designers need to be aware that design codes and specifica-tions may not recognize the use of the No.20 64 bar,the largest bar sizeincluded in this specification.Structural members reinforced with No.2064 bars may require approval of the building official or other appro

9、 for usewhere bend testing of bar designation Nos.14 and 18 43,57,and bar designation Nos.40,50,and 60 in Annex A1,isrequired by the purchaser.The supplementary requirementapplies only when specified in the purchase order.1.7 The text of this specification references notes andfootnotes which provide
10、 explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of the specification.1.8 This specification is applicable for orders in eitherinch-pound units(as Specification A1035)or in SI units(asSpecification A1035M).1.9 The values stat
11、ed in either inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may res
