Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 carbon steelsteel is considered to be carbon steel (1)when no minimum content is specified or required for alumi-num, chromium, cobalt, columbium, molybdenum, nickel,titanium, tungsten, vanadium, or zirconium
7、or any otherelement is added to obtain a desired alloying effect; (2) whenthe specified minimum copper content does not exceed 0.40 %;or (3) when the maximum specified content for any of thefollowing elements does not exceed these percentages: man-ganese 1.65, silicon 0.60, or copper 0.60.3.1.2 alum
8、inum-coated (aluminized) wirealuminum-coated (aluminized) wire is produced by passing individualwires through a bath of molten aluminum, after first beingproperly preheated, cleaned, and pickled.3.1.3 temperas applied to aluminum-coated (aluminized)wire, pertains to stiffness or resistance to bendin
9、g. It hascustomarily been expressed by tensile strength as shown in thethree ranges given in Table 1. The temper of a given chemicalcomposition can be controlled by the use of a different thermaltreatment for each temper. Different properties can also beobtained by varying the chemical composition f
10、or a giventhermal treatment. A thorough understanding of the end use ofthe wire, which involves both tensile strength and ductility,should be reached between the user and the manufacturer of thealuminum-coated (aluminized) wire. Requirements for bothchemical composition and mechanical properties may
11、 betechnologically impracticable.4.

16、.5. Materials and Manufacture5.1 The steel rod from which the wire is produced shall bemanufactured by any commercially accepted steel makingpractice.5.2 The ingot or pig aluminum used for coating shallconform to the following impurity limits:max, %CopperIron0.100.506. Mechanical Properties6.1 The a
17、luminum-coated wire shall meet the tensilestrength in accordance with Table 1 when tested in accordancewith Test Methods and Definitions A 370.6.2 Test specimens containing a weld or an obvious defectshall be discarded and another test specimen obtained to verifyconformance to the tensile strength r
18、equirements.7. Dimensions and Tolerances7.1 The permissible variation in diameter of the aluminum-coated wire as represented by the test specimens shall be inaccordance with Table 2.8. Weight of Coating8.1 The aluminum-coated wire as represented by the testspecimens tested in accordance with Test Me
19、thod A 428, shallhave a minimum weight of aluminum coating in accordancewith Table 2.9. Adherence of Coating9.1 The aluminum-coated wire as represented by the testspecimens shall be capable of being wrapped in a close helix ata rate not exceeding 15 turns/min around a cylindrical steelmandrel having
20、 a diameter equal to three times the nominaldiameter of the coated wire under test, without cracking orflaking the aluminum coating to such an extent that anyaluminum can be removed by rubbing with the bare fingers.9.2 Loosening or detachment during the adhesion test ofsuperficial, small particles o
21、f aluminum formed by mechanicalpolishing of the surface of the aluminum-coated wire shall notbe considered cause for rejection.10. Workmanship10.1 The aluminum-coated wire shall be free of slivers,scale, and other imperfections not consistent with good com-mercial practice. The coating shall be cont
22、inuous and reason-ably uniform. To ensure large continuous length coils, weldsmay be present in the finished wire.11. Number of Tests and Retests11.1 Alot shall consist of all of the coils of wire of the samesize, type and class, and shall be offered for inspection at onetime. A wire sample of suffi
23、cient length, approximately 4 ft.(1.2 m), shall be cut from either end of each coil selected fortests described in Sections 6, 8, and 9.11.2 The number of test specimens taken from the ends ofcoils during production to assure compliance with Sections 6and 7 varies with the quality control procedures
24、 and themanufacturing facilities of each manufacturer, but is generallynot less than 10 % of the coils produced. For the purpose offinal product testing, one specimen from every ten coils orfraction thereof in a lot shall be selected at random, or a totalof seven specimens, whichever is less.11.3 Sh
25、ould one or more of the wire specimens fail anyrequirement, the lot shall be subjected to retest. For retestpurposes the original lot shall be regrouped into 50 coil lots orfractions thereof. Each lot shall be tested for the property inwhich the original sample failed to comply at a frequency of10 %
26、 or more so that the total number of tests is at least doublethe original. Any lot that exhibits a failure shall be rejected. Ifduring retesting an additional quality parameter is observed tobe defective, the lot of 50 is subject to rejection for that cause.The manufacturer may test each coil in the
27、 failed lot for theproperty in which failure occurred and reject only the noncon-forming coils.12. Inspection12.1 Unless otherwise specified in the contract or purchaseorder, the manufacturer is responsible for the performance ofall inspection and test requirements specified in this specifica-tion.

If the tolerancesshown in this table are rigidly appl
33、ied to such irregularities that are inherent to theproduct, unjustified rejections of wire that would actually be satisfactory for usecould occur. Therefore, it is intended that these tolerances be used in gaging theuniform areas of the aluminized wire.A809082order, the manufacturer may use his own
