1、Designation: F2282 03 (Reapproved 2009)Standard Specification forQuality Assurance Requirements for Carbon and Alloy SteelWire, Rods, and Bars for Mechanical Fasteners1This standard is issued under the fixed designation F2282; the number immediately following the designation indicates the year ofori

2、ginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes quality assurance require-ments

3、 for the physical, mechanical, and metallurgical require-ments for carbon and alloy steel wire, rods, and bars in coilsintended for the manufacture of mechanical fasteners whichincludes: bolts, nuts, rivets, screws, washers, and special partsmanufactured cold.NOTE 1The Steel Industry uses the term “

4、quality” to designatecharacteristics of a material which make it particularly well suited to aspecific fabrication and/or application and does not imply “quality” in theusual sense.1.2 Wire size range includes 0.062 to 1.375 in.1.3 Rod size range usually includes732 in. (0.219) to4764 in.(0.734) and

5、 generally offered in164 increments (0.0156).1.4 Bar size range includes38 in. (0.375) to 112 in. (1.500).1.5 Sizes for wire, rod and bar outside the ranges ofparagraphs 1.2-1.4 may be ordered by agreement betweenpurchaser and supplier.1.6 Material is furnished in many application variations.The pur

6、chaser should advise the supplier regarding the manu-facturing process and finished product application as appropri-ate. Five application variations are:Cold HeadingRecessed HeadSocket HeadScrapless NutTubular Rivet1.6.1 Wire is furnished for all five application variations.1.6.2 Rod and bar are fur

In producing AIP and SAIP wire,rods or bars are drawn to wire and thermal treatment (followedby a separate cleaning and coating ope

24、ration) is done prior tofinal drawing to produce a softer and more ductile wire forapplications in which direct drawn wire would be too hard.Thermal treatment may also be employed when controlledmechanical properties are required for a specific application.3.2 Heat treating terms not defined in this
