The steelmay be either ingot cast or strand cast.5.2 A sufficient discard shall be made to ensure freedomfrom detrimental piping and undue segregation.5.3 The wire shall be cold-drawn to produce the desiredproperties.5.4 The wire shall be furnished in one of five types, asspecified5.4.1 Uncoated,5.4.2 Drawn-galvanized,5.4.3 Final-galvanized,5.4.4 Drawn Zn5/Al-MM, and5.4.5 Final coated Zn5/Al-MM.5.5 Uncoated, drawn-galvanized and drawn-Zn5 Al-MMwire can be furnished in Levels 1 through 5. Final-galvanizedand final-coated Zn5 Al-MM wire is usually furnished inLevels 1 through 4.5.6 The method utilized in the production of either drawn-or final-galvanized wire types may be by an electro-depositionor hot-dip galvanizing process at the option of the producer.5.6.1 The slab zinc used in galvanized zinc coatings shall beas specified in Specification B6.5.7 The method utilized in the production of Zn5 Al-MMwire types may be either a continuous hot-dip alloy coating ortwo step coating where the first coating is zinc followed by afinal bath having an aluminum content up to 7.2 to preventdepletion of the aluminum content of the bath.5.7.1 The bath metal used in continuous hot-dip Zn-5Al-MM alloy coating shall meet the chemical compositionlimits specified in Specification B750.6. Chemical Composition6.1 Upon agreement with the purchaser, the wire manufac-turer shall apply a steel of suitable chemical composition thatwill satisfy the properties of the material ordered.6.2 A quantitative analysis of each cast or heat shall bemade by the steel producer or his representative to determinethe percentage of the elements specified. The analysis shall bemade from a test sample preferably taken during the pouring ofthe cast or heat. The chemical composition thus determinedshall be reported, if required, to the purchaser or his represen-tative.6.3 An analysis may be made by the purchaser from thefinished wire. The chemical composition thus determined as tothe elements required shall conform to the product analysisrequirements specified in Table 3 of Specification A510 or asagreed upon between the purchaser and the manufacturer.7.

The loadingrate may be greater than that specified, depending on thenumber of tests to be carried out for the batch inspection.However, it shall not exceed the rate corresponding to a 25 elongation between anchorages in 1 min. The minimumdistance between the clamping jaws of the test machine is 4 in.100 mm. In the event of a dispute, the tensile test shall becarried out strictly in accordance with Test Methods E8,inparticular with regard to the loading rate.8.1.3 The minimum breaking forces are specified in Table 3of this specification, for wire grade Levels 1 through 5. Therange in breaking force for a given grade level is based on thecalculated minimum tensile strength requirement psi. Whileno maximum values are shown for breaking force, rope wire isgenerally produced to a tensile strength range of 30 000 psi.The resultant minimum breaking force of either uncoated,drawn-galvanized, and drawn-Zn5 Al-MM wires of variouslevels shall meet or exceed the values shown in Table 3. Theresultant minimum breaking force for final-galvanized orfinal-coated Zn5Al-MM wire is obtained by reducing the valuestated for its level in Table 3 for uncoated wire by 10 .TABLE 3 Minimum Breaking ForcesWire Diameter Minimum Torsional ValuesNumber of Twists in 8 in.Minimum Breaking ForceAin. mm Level 1 Level 2 Level 3 Level 4 Level 5 Level 1 Level 2 Level 3 Level 4 Level 5lbf N lbf N lbf N lbf N lbf N0.010 0.254 274 254 234 218 190 16 70 17 80 20 90 22 100 24 1100.011 0.279 249 231 213 196 173 18 90 21 100 24 110 27 120 29 1300.012 0.305 228 212 195 182 158 22 100 25 120 29 130 32 150 31 1600.013 0.330 211 196 180 168 146 26 120 29 140 34 150 37 170 41 1800.014 0.356 196 181 167 156 136 31 140 34 160 39 180 43 200 45 2100.015 0.381 182 169 156 145 126 36 180 39 180 45 200 49 220 53 2400.016 0.408 171 156 146 136 118 40 180 41 200 51 230 56 250 60 2700.017 0.432 161 149 137 126 111 48 200 50 230 57 260 63 290 68 3000.018 0.467 152 141 130 121 105 50 230 53 250 64 290 71 320 76 3400.019 0.483 144 133 123 114 100 56 250 62 260 72 320 79 360 85 3800.020 0.508 136 126 116 108 94 60 280 69 310 79 360 87 390 94 4200.021 0.533 130 120 111 103 90 68 310 73 340 87 390 96 430 100 4500.022 0.559 124 115 106 96 86 75 340 83 360 96 430 110 490 110 4900.023 0.584 118 110 101 94 82 80 370 91 410 100 450 120 540 120 5400.024 0.610 113 105 97 90 78 85 400 100 450 110 490 130 580 130 5800.025 0.635 109 101 93 86 75 90 430 110 490 120 540 140 630 150 6700.026 0.680 105 97 89 83 72 100 450 130 540 130 560 150 670 160 7200.027 0.686 101 93 86 80 70 110 490 130 580 140 630 160 720 170 7300.028 0.711 97 90 83 77 67 120 540 130 580 150 670 170 760 180 8100.029 0.737 94 87 80 74 65 130 580 140 630 170 760 180 810 200 8900.030 0.782 90 84 77 72 62 140 630 150 670 180 810 190 850 210 9400.031 0.787 86 81 75 69 60 150 670 160 720 190 850 210 940 220 9600.032 0.813 85 78 72 67 56 160 720 180 810 200 890 220 980 240 10700.033 0.836 82 76 70 65 57 170 780 190 850 210 940 240 1070 250 11300.034 0.864 80 74 68 63 55 180 810 200 890 230 1030 250 1120 270 12100.035 0.869 77 72 66 61 53 190 860 210 940 240 1070 260 1160 280 12500.036 0.914 75 70 64 60 52 200 890 220 960 250 1120 280 1250 300 13400.037 0.940 73 68 62 58 50 210 940 230 1030 270 1210 300 1340 320 14300.038 0.966 71 66 61 56 49 220 960 250 1120 280 1250 310 1360 330 14700.039 0.991 69 64 59 55 48 230 1030 260 1160 300 1340 330 1470 350 15600.040 1.02 67 62 57 53 46 240 1070 270 1210 310 1360 340 1520 370 16500.041 1.04 66 61 56 52 45 250 1160 290 1290 330 1470 360 1610 390 17400.042 1.07 64 59 55 51 44 270 1210 300 1340 340 1520 380 1700 410 18300.043 1.09 63 58 53 50 43 280 1250 310 1380 360 1610 400 1780 430 19200.044 1.12 61 57 52 48 42 300 1340 330 1470 380 1700 420 1870 450 20100.045 1.14 60 56 51 47 41 310 1360 340 1520 390 1740 430 1920 470 21000.046 1.17 58 54 50 46 40 320 1430 360 1610 410 1830 450 2010 490 21300.047 1.19 57 53 49 45 39 340 1530 370 1650 430 1920 470 2100 510 2270TABLE 2 Wire Diameter Tolerances Final-Galvanized or Final-Coated Zn5 Al-MM Rope WireDiameter Range, in.
