A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers low-carbon, chromium, steel bars, de
3、formed and plain for concrete reinforcement in cut lengthsand coils. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. The text of thisspecification references notes and footnotes which provide explanatory material. These notes and footnotes (excl
4、uding those intables and figures) shall not be considered as requirements of the specification.21.2 Bars are of two minimum yield strength levels as defined in 9.2: namely, 100 000 psi 690 MPa, and 120 000 830 MPadesignated as Grade 100 690 and Grade 120 830, respectively.NOTE 1Caution: Designers ne
5、ed to be aware that typical design standards limit the design strength to 80 000 psi 550 MPa, except for prestressingsteel and for spiral transverse reinforcement. Members reinforced with bars with yield strengths that are considerably above 80 000 psi 550 MPa mayexhibit behavior that differs from t
6、hat expected of conventional reinforced concrete members or may require special detailing to ensure adequateperformance at service and factored loads.1.3 Deformed bars shall have a minimum yield strength and other tensile properties in accordance with Table 2. Hot-rolled plainrounds in sizes up to a
7、nd including 2.25 in. 57.2 mm in diameter in coils or cut lengths when specified for dowels, spirals,structural ties or bar supports shall be furnished under this specification and shall also meet the tensile properties requirements ofTable 2. Ductility properties for plain rounds shall be those of
8、the nearest smaller nominal diameter deformed bar size in Table2. Requirements covering deformation dimensions and marking are not applicable to plain rounds.NOTE 1Welding of the material in this specification should be approached with caution since no specific provisions have been included to enhan
9、ceits weldability. When this steel is to be welded, a welding procedure suitable for the chemical composition and intended use or service should be used.1.4 Requirements for alternate bar sizes are presented in Annex A1. The requirements in Annex A1 only apply when specifiedby the purchaser (see 4.1
10、.10).1.5 This specification is applicable for orders in either inch-pound units (as Specification A1035) or in SI units (as SpecificationA1035M).1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shownin brackets. The values
11、 stated in each system are not exact equivalents; therefore, each system must be used independently of theother. Combining values from the two systems may result in nonconformance with the specification.2. Referenced Documents2.1 ASTM Standards:3A6/A6M Specification for General Requirements for Roll

Such requirements shall include but are not limited to the following:4.1.1 Quantity (weight) mass,4.1.2 Name of material: low-carbon, chromium, steel bars for concrete reinforcement,4.1.3 Size,4.1.4 Cut lengths or coils,4.
31、1.5 Deformed or plain,4.1.6 Grade,4.1.7 Packaging (see Section 21),4.1.8 ASTM designation and year of issue, and4.1.9 Certified mill test reports, and4.1.10 Optional requirements of Annex A1, if applicable.5. Materials and Manufacture5.1 The bars shall be rolled from properly identified heats of mol
32、d cast or strand cast steel using the basic oxygen,electric-furnace, or open-hearth process.6. Chemical Composition6.1 The chemical analysis of each heat shall be determined in accordance with Test Methods, Practice, and Terminology A751.The manufacturer shall make the analysis on test samples taken
33、 preferably during the pouring of the heat. The percentages ofcarbon, manganese, phosphorus, sulfur, silicon, chromium, and nitrogen, shall be determined and reported as required in Section16.6.2 The chemical composition as shown by heat analysis shall be limited by the following:Element max, %ACarb
34、on 0.15 %Chromium 8.0 to 10.9 %Manganese 1.5 %Nitrogen 0.05 %Phosphorus 0.035 %Sulfur 0.045 %Silicon 0.50 %A Maximum unless range is indicated percentages refer to weight percentages.7. Requirements for Deformation7.1 Deformations shall be spaced along the bar at substantially uniform distances. The
35、 deformations on opposite sides of thebar shall be similar in size, shape, and pattern.7.2 The deformations shall be placed with respect to the axis of the bar so that the included angle is not less than 45. Wherethe line of deformations forms an included angle with the axis of the bar from 45 to 70
36、 inclusive, the deformations shall alternatelyreverse in direction on each side, or those on one side shall be reversed in direction from those on the opposite side. Where theline of deformations is over 70, a reversal in direction shall not be required.7.3 The average spacing or distance between de
37、formations on each side of the bar shall not exceed seven tenths of the nominaldiameter of the bar.7.4 The overall length of deformations shall be such that the gap (measured as a chord) between the ends of the deformationson opposite sides of the bar shall not exceed 1212 % of the nominal perimeter
38、 of the bar.Where the ends terminate in a longitudinalrib, the width of the longitudinal rib shall be considered the gap. Where more than two longitudinal ribs are involved, the totalwidth of all longitudinal ribs shall not exceed 25 % of the nominal perimeter of the bar; furthermore, the summation
39、of gaps shallnot exceed 25 % of the nominal perimeter of the bar. The nominal perimeter of the bar shall be 3.1416 times the nominal diameter.7.5 The spacing, height, and gap of deformations shall conform to the requirements prescribed in Table 1.8. Measurements of Deformation8.1 The average spacing
40、 of deformations shall be determined by measuring the length of a minimum of 10 spaces and dividingthat length by the number of spaces included in the measurement. The measurement shall begin from a point on a deformation atthe beginning of the first space to a corresponding point on a deformation a
41、fter the last included space. Spacing measurements shallnot be made over a bar area containing bar marking symbols involving letters or numbers.A1035/A1035M 13a38.2 The average height of deformations shall be determined from measurements made on not less than two typical deformations.Determinations
42、shall be based on three measurements per deformation, one at the center of the overall length and the other twoat the quarter points of the overall length.8.3 Insufficient height, insufficient circumferential coverage, or excessive spacing of deformations shall not constitute cause forrejection unle
43、ss it has been clearly established by determinations on each lot tested that typical deformation height, gap, or spacingdo not conform to the minimum requirements prescribed in Section 7. No rejection shall be made on the basis of measurementsif fewer than ten adjacent deformations on each side of t
44、he bar are measured.9. Tensile Requirements9.1 The material, as represented by the test specimens, shall conform to the requirements for tensile properties prescribed inTable 2.9.2 The yield strength shall be determined by the offset method (0.2 % offset), described in Test Methods and Definitions A
45、370.In addition, the stress corresponding to a tensile strain of 0.0035 shall be a minimum of 80 000 psi 550 MPa for Grade 100 and90 000 psi 620 MPa for Grade 120.NOTE 2The stress-strain curves for bars meeting this specification do not have a well-defined yield point (that is, yield is not characte
46、rized by a sharpknee or discontinuity similarly to stainless steel bars). The provisions of 9.2 require that the yield strength (minimum 100 000 psi for Grade 100 690MPa and minimum 120 000 psi for Grade 120 830 MPa, respectively) be measured by the 0.2 % offset method and that the stress correspond
47、ing toa strain of 0.0035 be a minimum of 80 000 psi for Grade 100 and 90 000 psi 620 MPa for Grade 120. Experimental results for concrete beams reinforcedwith bars meeting this specification show that the flexural strength of under-reinforced members is conservatively predicted based on the yield st
48、rengthmeasured using the 0.2 % offset method. The minimum stress corresponding to a tensile strain of 0.0035 is required to ensure that the specified steel isat least as stiff at lower strains as lower-strength reinforcing bars.9.3 The percentage of elongation shall be as prescribed in Table 2.10. Bending Requirements10.1 The bend test specimen shall withstand being bent around a pin without cracking on the outside radius of the bent portion.The requirements for degree of bending and sizes of pins are prescribed in Table 3.
