Terminology 3.1 Defi nitions of Terms Specifi c to This Standard: 3.1.1 carbon steelsteel is considered to be carbon steel when no minimum content is specifi ed or required for alumi- num, chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, or zirconium, or any other element added to obtain a desired alloying effect; when the specifi ed minimum for copper does not exceed 0.40 %; or when the maximum content specifi ed for any of the following elements does not exceed these percentages: manganese 1.65, silicon 0.60, or copper 0.60. 3.1.2 Discussion In all carbon steels small quantities of certain unspecifi ed and unrequired residual elements (such as copper, nickel, molybdenum, chromium, etc.) unavoidably retained from raw materials are sometimes found. These elements are considered as incidental and are not normally determined or reported. Elements (such as sulfur and lead) may be specifi ed to improve machinability of carbon steels. 3.1.3 coarse round wirefrom 0.90 to 25 mm in diameter, inclusive, wire produced from hot-rolled wire rods or hot- rolled coiled rounds by one or more cold reductions primarily for the purpose of obtaining a desired size with dimensional accuracy, surface fi nish, and mechanical properties. By varying the amount of cold reduction and other wire mill practices, including thermal treatment, a wide diversity of mechanical properties and fi nishes are made available. Suggested wire diameters are shown in Table 1. 3.1.4 straightened and cut wirewire produced from coils of wire by means of special machinery that straightens the wire and cuts it to a specifi ed length. 3.1.5DiscussionThe straightening operation may alter the mechanical properties of the wire, especially the tensile strength. The straightening operation may also induce changes 1 This specifi cation is under the jurisdiction of ASTM Committee A-1 on Steel, Stainless Steel, and Related Alloys and is the direct responsibility of Subcommittee A01.03 on Steel Rod and Wire.

The extent of the changes in the properties of the wire after cold straightening depends upon the kind of wire and also on the normal variation in the adjust- ments of the straightening equipment. It is therefore not possible to forecast the properties of straightened and cut wire. Each kind of wire needs individual consideration. In most cases, the application of straightened and cut wire is not seriously infl uenced by these changes. 3.1.6 wire rodsrods that are hot rolled from billets to an approximately round cross section and into coils of one continuous length. Rods are not comparable to hot-rolled bars in accuracy of cross section or surface fi nish and as a semi-fi nished product are intended primarily for the manufac- ture of wire. 3.1.7 DiscussionTable 2 shows the nominal diameter for hot-rolled wire rods. Sizes are shown in 0.5-mm increments from 5.5 to 19 mm. 4. Ordering Information 4.1 Orders for hot-rolled wire rods under this specifi cation should include the following information: 4.1.1 Quantity (kilograms or megagrams), 4.1.2 Name of material (wire rods), 4.1.3 Diameter (Table 2), 4.1.4 Chemical composition grade number (Table 3, Table 4, Table 5, and Table 6), 4.1.5 Packaging, 4.1.6 ASTM designation and date of issue, and 4.1.7 Special requirements, if any_. NOTE2A typical ordering description is as follows: 50 000 kg Steel Wire Rods, 5.5 mm, Grade G10100 in approximately 600-kg Coils to ASTM A 510M-XX. 4.2 Orders for coarse round wire under this specifi cation shall include the following information: 4.2.1 Quantity (kilograms or pieces), 4.2.2 Name of material (uncoated carbon steel wire), 4.2.3 Diameter (Table 1), 4.2.4 Length (straightened and cut only), 4.2.5 Chemical composition (Table 3, Table 4, Table 5, and Table 6), 4.2.6 Packaging, 4.2.7 ASTM designation and date of issue, and 4.2.8 Special requirements, if any. NOTE3A typical ordering description is as follows: 15 000 kg Uncoated Carbon Steel Wire, 3.8 mm diameter, Grade G10080 in 1000-kg Coils on Tubular Carriers, to ASTM A 510M-XX, or 2500 Pieces, Carbon Steel Wire, 9.5 mm diameter, Straightened and Cut, 0.76 m, Grade G10500, in 25-Piece Bundles on Pallets to ASTM A 510M-XX. 5. Manufacture 5.1 The steel may be made by any commercially accepted steel making process. The steel may be either ingot cast or strand cast. 6. Chemical Composition 6.1 The chemical composition for steel under this specifi - cation shall conform to the requirements set forth in the purchase order. Chemical compositions are specifi ed by ranges or limits for carbon and other elements. The grades commonly specifi ed for carbon steel wire rods and coarse round wire are shown in Table 3, Table 4, Table 5, and Table 6. 6.2 Cast or Heat AnalysisAn analysis of each heat shall be made by the producer to determine the percentage of the elements specifi ed. The analysis shall be made from a test sample, preferably taken during the pouring of the heat. The chemical composition thus determined shall be reported, if required, to the purchaser or his representative. 6.3 Product AnalysisA product analysis may be made by the purchaser. The analysis is not used for a duplicate analysis to confi rm a previous result. The purpose of the product analysis is to verify that the chemical composition is within specifi ed limits for each element, including applicable permis- sible variations in product analysis. The results of analyses taken from different pieces of a heat may differ within permissible limits from each other and from the heat analysis. Table 7 shows the permissible variations for product analysis of carbon steel. The results of the product analysis, except lead, shall not vary both above and below the permissible limits. 6.3.1 Rimmed or capped steels are characterized by a lack TABLE 1Suggested Diameters for Steel Wire, mm 0.906.0 1.006.5 1.107.0 1.207.5 1.308.0 1.408.5 1.609.0 1.809.5 2.010.0 2.111.0 2.212.0 2.413.0 2.514.0 2.615.0 2.816.0 3.017.0 3.218.0 3.519.0 3.820.0 4.021.0 4.222.0 4.523.0 4.824.0 5.025.0 5.5 TABLE 2Sizes of Wire Rods, mm 5.512.5 613 6.513.5 714 7.514.5 815 8.515.5 916 9.516.5 1017 10.517.5 1118 11.518.5 1219 A 510M 2 of uniformity in their chemical composition, especially for the elements carbon, phosphorus, and sulfur, and for this reason product analysis is not technologically appropriate for these elements unless misapplication is clearly indicated. 6.3.2 Because of the degree to which phosphorus and sulfur segregate, product analysis for these elements is not techno- logically appropriate for rephosphorized or resulfurized steels, or both, unless misapplication is clearly indicated. TABLE 3Nonresulfurized Carbon Steel Cast or Heat Chemical Ranges and Limits NOTE1SiliconWhen silicon is required the following ranges and limits are commonly used for nonresulfurized carbon steels: 0.10 max %, 0.07 to 0.15 %, 0.10 to 0.20 %, 0.15 to 0.35 %, 0.20 to 0.40 %, or 0.30 to 0.60 %. NOTE 2CopperWhen required, copper is specifi ed as an added element. NOTE 3LeadWhen lead is required as an added element, a range from 0.15 to 0.35 % is specifi ed. Such a steel is identifi ed by inserting the letter “L” between the second and third numerals of the grade number, for example, 10L18. NOTE 4Boron Addition to Improve HardenabilityStandard killed carbon steels, which are fi ne grain, may be produced with a boron addition to improve hardenability. Such steels are produced to a range of 0.0005 to 0.003 % boron. These steels are identifi ed by inserting the letter “B” between the second and third numerals of the grade number, for example, 10B46. The UNS designation is also modifi ed by changing the last digit to “1” to indicate boron, for example, G 10461. NOTE5Boron Additions to Control Strain-Ageing BehaviorIntentional additions of Boron to low carbon steels for the purpose of controlling strain-ageing behavior during wire drawing is permissible only with the agreement of the purchaser. In such cases, the Boron content shall be reported in either a material test report or certifi cation.

A 510M 3 6.3.3 The location at which chips for product analysis are obtained from the sample is important because of segregation. For rods and wire, chips must be taken by milling or machining the full cross section of the sample. Steel subjected to certain heat treating operations by the purchaser may not give chemical analysis results that properly represent its original composition. Therefore, pur- chasers should analyze chips taken from the steel in the condition in which it is received from the producer. When samples are returned to the producer for product analysis, the samples should consist of pieces of the full cross section. 6.3.4 For referee purposes, Test Methods E 30 shall be used. 7. Metallurgical Structure 7.1 Grain size, when specifi ed, shall be determined in accordance with the requirements of Test Methods E 112. 7.2 Wire rods of the steel grades listed in Table 3, when supplied in the “as-rolled condition, shall not contain injuri- ous microconstituents such as untempered martensite.
