The manufacturer shall make the analysis on testsamples taken preferably during the pouring of the heat. Thepercentages of carbon, manganese, phosphorus
33、, sulfur, silicon,chromium, and nitrogen, shall be determined and reported asrequired in Section 16.6.2 The chemical composition for the different Alloy Typesas shown by heat analysis shall be limited to Table 2 of thisspecification.7. Requirements for Deformations7.1 Deformations shall be spaced al
34、ong the bar at substan-tially uniform distances. The deformations on opposite sides ofthe bar shall be similar in size, shape, and pattern.7.2 The deformations shall be placed with respect to the axisof the bar so that the included angle is not less than 45. Wherethe line of deformations forms an in
35、cluded angle with the axisof the bar from 45 to 70 inclusive, the deformations shallalternately reverse in direction on each side, or those on oneside shall be reversed in direction from those on the oppositeside. Where the line of deformations is over 70, a reversal indirection shall not be require
36、d.7.3 The average spacing or distance between deformationson each side of the bar shall not exceed seven tenths of thenominal diameter of the bar.7.4 The overall length of deformations shall be such that thegap (measured as a chord) between the ends of the deforma-tions on opposite sides of the bar
37、shall not exceed 1212 %ofthe nominal perimeter of the bar. Where the ends terminate ina longitudinal rib, the width of the longitudinal rib shall beconsidered the gap. Where more than two longitudinal ribs areinvolved, the total width of all longitudinal ribs shall notexceed 25 % of the nominal peri
38、meter of the bar; furthermore,the summation of gaps shall not exceed 25 % of the nominalperimeter of the bar. The nominal perimeter of the bar shall be3.1416 times the nominal diameter.7.5 The spacing, height, and gap of deformations shallconform to the requirements prescribed in Table 1.8. Measurem
39、ents of Deformations8.1 The average spacing of deformations shall be deter-mined by measuring the length of a minimum of 10 spaces anddividing that length by the number of spaces included in themeasurement. The measurement shall begin from a point on adeformation at the beginning of the first space
40、to a correspond-ing point on a deformation after the last included space.Spacing measurements shall not be made over a bar areacontaining bar marking symbols involving letters or numbers.8.2 The average height of deformations shall be determinedfrom measurements made on not less than two typical def
41、or-mations. Determinations shall be based on three measurementsper deformation, one at the center of the overall length and theother two at the quarter points of the overall length.8.3 Insufficient height, insufficient circumferentialcoverage, or excessive spacing of deformations shall notconstitute
42、 cause for rejection unless it has been clearly estab-lished by determinations on each lot tested that typical defor-mation height, gap, or spacing do not conform to the minimumrequirements prescribed in Section 7. No rejection shall bemade on the basis of measurements if fewer than ten adjacentdefo
43、rmations on each side of the bar are measured.9. Tensile Requirements9.1 The material, as represented by the test specimens, shallconform to the requirements for tensile properties prescribed inTable 3.9.2 The yield strength shall be determined by the offsetmethod (0.2 % offset), described in Test M
44、ethods and Defini-tions A370.9.3 When material is furnished in coils, the test specimenshall be taken from the coil and straightened prior to placing itin the jaws of the tensile testing machine. (See Note 3.)NOTE 3Straighten the test specimen to avoid formation of local sharpbends and to minimize c
45、old work. Insufficient straightening prior toattaching the extensometer can result in lower-than-actual yield strengthreadings.9.3.1 Test specimens taken from post-fabricated materialshall not be used to determine conformance to this specifica-tion. (See Note 4.)NOTE 4Multiple bending distortion fro
46、m mechanical straighteningand fabricating machines can lead to excessive cold work, resulting inhigher yield strengths, lower elongation values, and a loss of deformationheight.9.4 The percentage of elongation shall be as prescribed inTable 3.10. Bending Requirements10.1 The bend test specimen shall
47、 withstand being bentaround a pin without cracking on the outside radius of the bentportion. The requirements for degree of bending and sizes ofpins are prescribed in Table 4. When material is furnished incoils, the test specimen shall be straightened prior to placementin the bend tester.10.2 The be
48、nd test shall be made on specimens of sufficientlength to ensure free bending and with apparatus that provides:TABLE 3 Tensile Properties RequirementsType A1035 CL A1035 CM A1035 CSGrade Grade 100 690 Grade 120 830 Grade 100 690 Grade 120 830 Grade 100 690 Grade 120 830Tensile strength, min, psi MPa 150 000 1030 150 000 1030 150 000 1030 150 000 1030 150 000 1030 150 000 1030Yield strength (0.2 % offset), min, psiMPa100 000 690 120 000 830 100 000 690 120 000 830 100 000 690 120 000 830Elongation in 8 in. 200 mm, min, %:Bar Designation No.3 through
