1、Designation: A 489 04e1Standard Specification forCarbon Steel Lifting Eyes1This standard is issued under the fixed designation A 489; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthese
2、s indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.e1NOTESections 2.2 and 3.1.10 were editorially revised in October 2006.1. Scope*1.1 T
3、his specification covers weldless forged, quenched,and tempered carbon steel threaded lifting eyes (formerlyeyebolts) for overhead lifting.NOTE 1Lifting eyes carrying this specification number even thoughthey are liquid quenched and tempered may be processed from carbonsteel which, in the compositio
4、n range permitted by this specification,could have a fracture appearance transition temperature (50 % shear)higher than operating temperatures. Therefore, in order to minimize thepossibility of a brittle cleavage failure, these lifting eyes should never beloaded above the proof load, and should not
5、be used when surfacediscontinuities exist on the lifting eyes.1.2 The specification includes two types denoting shankpattern and one style denoting shank length (both defined inASME B 18.15) as follows:1.2.1 Type 1Plain pattern (straight shank).1.2.2 Type 2Shoulder pattern.1.2.3 Style BShort length.
6、1.3 The values stated in inch-pound units are to be regardedas the standard. The SI values given in parentheses are forinformation only.1.4 Terms used in this specification are defined in Termi-nology F 1789 unless otherwise defined herein.2.

Chemical Composition5.1 LimitsThe lifting eyes shall be manufacture
16、d fromsteels having a heat analysis conforming to the requirements inTable 1.5.2 Product Analysis:5.2.1 Analyses of finished lifting eyes may be made by thepurchaser or may be requested to be made by the manufacturer.The composition thus determined shall conform to the productanalysis requirements s
17、pecified in Table 1.5.3 Chemical analyses shall be performed in accordancewith Test Methods, Practices, and Terminology A 751.6. Mechanical Properties6.1 Proof LoadThe lifting eyes shall withstand the proofload specified in Table 2.6.1.1 The proof load shall be defined as the load that can beapplied
18、 without causing permanent deformation exceeding0.01 in. (0.255 mm) between prick punch marks at oppositeends of the diameter across the eye. The proof load shall beapplied through a mandrel having a diameter of one half thenominal inside diameter of the eye.6.2 Breaking StrengthThe lifting eyes sha
19、ll conform tothe breaking strength specified in Table 2.6.2.1 The breaking strength shall be determined by screw-ing the lifting eye to the full thread engagement into a blocksecured in one jaw of the testing machine and held to the otherjaw by means of a mandrel passing through the eye. Failure oft
20、he lifting eye below the specified breaking strength constitutesa failure.6.3 Tensile Test RequirementsA specimen machined froma finished lifting eye shall conform to the tensile requirementsspecified in Table 3.6.3.1 When the lifting eye is too small to have a tensile barmachined from it, a test sp
21、ecimen from the same heat of steeland same heat treatment lot or charge as the lifting eyes to betested shall be used to establish the tensile properties of thematerial in accordance with 6.3.6.3.2 The tensile properties shall be determined in accor-dance with Test Methods F 606.6.4 Bend TestType 1
22、straight shank lifting eyes 112 in.(36.1 mm) or less in diameter, after being screwed into a steelblock to the full thread length and bent 45 by pressure, shallnot exhibit any visible surface ruptures in the unthreadedsection of the lifting eye when examined at 103 magnification.6.5 Impact StrengthT
23、he lifting eyes shall have an averageCharpy V-notch impact strength of not less than 35 ftlbf (47 J)at 0C (32F).6.5.1 The impact strength shall be the average of threespecimens tested. Not more than one specimen shall exhibit avalue below the specified minimum average, and in no caseshall a value be
24、 less than 23 ftlbf (31 J).6.5.2 Whenever possible, test specimens shall be taken fromthe shank and shall conform to the standard 10 by 10-mmCharpy V-notch specimen shown in Test Methods and Defini-tions A 370. When lifting eyes are too small for standard-sizespecimens, subsize specimens may be used
