31、 bars, or nomial diameter (size) of plain bars,4.1.4 Cut lengths or coils,4.1.5 Grade, and4.1.6 ASTM designation A1035 A1035M and year-date of issue.4.2 The purchaser shall have the option to specify additional requirements, including but not limited to, the following:4.2.1 Certified mill test repor

32、ts (see Section 16),4.2.2 Special package marking requirements (21.220.2),4.2.3 Other special requirements, if any, and4.2.4 Optional requirements of Annex A1.5. Materials and Manufacture5.1 The bars shall be rolled from properly identified heats of mold cast or strand cast steel using the basic oxy

33、gen,electric-furnace, or open-hearthsteel. The steel shall be made by any commercially accepted 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 s

34、amples taken 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

35、 max, %ACarbon 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 mass percentages.7. Requirements for DeformationDeformations7.1 Deformations shall be spaced along the bar at substan

36、tially uniform distances. The 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

37、axis of the bar from 45 to 70 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 s

38、pacing or distance between deformations 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 12

39、12 % of the nominal perimeter 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

40、 furthermore, the summation 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.A1035/A1035M 1438. Measu

41、rements of DeformationDeformations8.1 The average spacing 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 th

42、e first space to a corresponding point on a deformation after the last included space. Spacing measurements shallnot be made over a bar area containing bar marking symbols involving letters or numbers.8.2 The average height of deformations shall be determined from measurements made on not less than

43、two typical deformations.Determinations 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 shal

44、l not constitute cause forrejection unless 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

45、 adjacent deformations on each side of the 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), des

46、cribed in Test Methods and Definitions A370.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 yie

47、ld point (that is, yield is not characterized 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 % offs

48、et method and that the stress corresponding 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 strengthmeasured 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 Whe
