1、Designation: A 752 04Standard Specification forGeneral Requirements for Wire Rods and Coarse RoundWire, Alloy Steel1This standard is issued under the fixed designation A 752; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers general requirements for alloysteel rods and uncoated coarse round alloy wire in coils
3、 that arenot required to meet hardenability band limits.1.2 In case of conflict, the requirements in the purchaseorder, on the drawing, in the individual specification, and inthis general specification shall prevail in the sequence named.1.3 The values stated in inch-pound units are to be regardedas

Terminology3.1 Description of Terms Specific to This Standard:3.1.1 alloy steel steel is considered to be alloy steel whenthe maximum of the range given for the content of alloyingelements exceeds one or more of the following limits: manga-nese 1.65 %, silicon 0.60 %, copper 0
7、.60 %; or in which adefinite range or a definite minimum quantity of any of thefollowing elements is specified or required within the limits ofthe recognized field of constructional alloy steels: aluminum,chromium up to 3.99 %, cobalt, columbium, molybdenum,nickel, titanium, tungsten, vanadium, zirc
8、onium, or any otheralloying elements added to obtain a desired alloying effect.Note that aluminum, columbium, and vanadium may also beused for grain refinement purposes.3.1.1.1 Boron treatment of alloy steels, which are fine grain,may be specified to improve hardenability.3.1.1.2 Other elements, suc
9、h as lead, selenium, tellurium, orbismuth, may be specified to improve machinability.3.1.2 coarse round wirefrom 0.035 to 0.999 in. (0.89 to25.4 mm) in diameter, inclusive, wire produced from hot-rolledwire rods or hot-rolled coiled bars by one or more coldreductions primarily for the purpose of obt
10、aining a desired sizewith dimensional accuracy, surface finish, and mechanicalproperties. By varying the amount of cold reduction and otherwire mill practices, including thermal treatment, a wide diver-sity of mechanical properties and finishes are made available.3.1.2.1 Coarse round wire is designa
11、ted by common frac-tions or decimal parts of an inch, or millimetres.3.1.3 wire rodsrods that are hot rolled from billets into anapproximate round cross section and into coils of one continu-ous length. Rods are not comparable to hot-rolled bars inaccuracy of cross section or surface finish and as a
12、 semi-finished product are primarily for the manufacture of wire.3.1.3.1 Rod sizes from732 to4764 in. (5.6 to 18.7 mm) indiameter, inclusive, are designated by fractions or decimalparts of an inch as shown in Table 1.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainl

All others are normallymanufactured by the basic open hearth or basic oxygen p
23、rocesses but may be manufactured by a basic electric furnace process. If the electric furnaceprocess is specified or required for grades other than those designated above, the limits for phosphorus and sulfur are respectively 0.025 % max.NOTE 2Small quantities of certain elements, which are not spec
24、ified or required, are present in alloy steels. These elements are considered asincidental and may be present to the following maximum amounts: copper, 0.35 %, nickel, 0.25 %, chromium, 0.20 %, molybdenum, 0.06 %.NOTE 3Where minimum and maximum sulfur content is shown it is indicative of resulfurize
25、d steel.NOTE 4The chemical ranges and limits shown in Table 2 are produced to check, product, or verification analysis tolerances shown in Table 4.NOTE 5Standard alloy steels can be produced with a lead range of 0.15 to 0.35 %. Such steels are identified by inserting the letter “L between thesecond
26、and third numerals of the Grade number, for example, 41L40. Lead is reported only as a range of 0.15 to 0.35 % since it is added to the moldas the steel is poured.UNS Desig-nationGrade No.Chemical Composition, Ranges and Limits, %Carbon ManganesePhos-phorus,maxSulfur,maxSilicon Nickel ChromiumMolyb-
