1、Designation: A 480/A 480M 04aStandard Specification forGeneral Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip1This standard is issued under the fixed designation A 480/A 480M; the number immediately following the designation indicates the yearof original adop
2、tion or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript 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.1.
3、 Scope*1.1 This specification2covers a group of general require-ments that, unless otherwise specified in the purchase order orin an individual specification, shall apply to rolled steel plate,sheet, and strip, under each of the following specificationsissued by ASTM: Specifications A 167, A 176, A
4、240/A 240M,A 263, A 264, A 265, A 666, A 693, A 793, and A 895.1.2 In the case of conflict between a requirement of aproduct specification and a requirement of this specification,the product specification shall prevail. In the case of conflictbetween a requirement of the product specification or are
5、quirement of this specification and a more stringent require-ment of the purchase order, the purchase order shall prevail.The purchase order requirements shall not take precedence ifthey, in any way, violate the requirements of the productspecification or this specification; for example, by waiving
6、atest requirement or by making a test requirement less stringent.1.3 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets, except that when A 480M isspecified, Annex A3 shall apply for the dimensional to
7、lerancesand not the bracketed SI values in Annex A2. The values statedin each system are not exact equivalents; therefore, eachsystem must be used independently of the other. Combiningvalues from the two systems may result in nonconformancewith the specification.1.4 This specification and the applic
8、able material specifica-tions are expressed in both inch-pound and SI units. However,unless the order specifies the applicable “M” specificationdesignation SI units, the material shall be furnished ininch-pound units.2.

Product Analysis7.1 The purchaser is permitted to perform a product analysis(formerly check analysis) to verify the identit
35、y of the finishedmaterial representing each heat or lot. Such analysis shall bemade by any of the commonly accepted methods that willpositively identify the material.7.2 The chemical composition determined in accordancewith 7.1 shall conform to the limits of the material specificationwithin the tole
36、rances of Table A1.1, unless otherwise specifiedin the applicable material specification or the purchase order.The allowable variation of a particular element in a singlesample for product analysis is permitted to be either above orbelow the specified range. However, percentages must exhibitthe same
37、 tendencies in all samples; that is, the severaldeterminations of any individual element in a heat shall notvary both above and below the specified range.8. Material Test Report and Certification8.1 A report of the results of all tests required by the productspecification shall be supplied to the pu
38、rchaser. This materialtest report shall reference the product specification designationand year date indicating that the material was manufactured,sampled, tested, and inspected in accordance with requirementsof the product specification and has been found to meet thoserequirements. The material tes
39、t report shall report the meltingprocess when the purchase order requires either a specific typeof melting or requires that the melting process used is to bereported.8.1.1 The report shall indicate the type of steel. If certifyingthat the material conforms to the requirements for more thanone type o
40、f steel, the manufacturer may indicate each type ofsteel on the report, or may issue a separate report for each typeof steel.8.2 A signature is not required on the report. However, thedocument shall clearly identify the organization submitting thereport. Not withstanding the absence of a signature,
41、theorganization submitting the document is responsible for itscontent.8.3 A material test report, certificate of inspection, or similardocument printed from or used in electronic form from anelectronic data interchange (EDI) transmission shall be re-garded as having the same validity as a counterpar

The content of the EDI transmitteddocument must meet the requirements of the invoked ASTMstandard(s) and conform to any existing EDI agreement be-tween the purchaser and the supplier. Notwithstanding theabsence of a signature, the organization submitting the EDIt
43、ransmission is responsible for the content of the report.8.4 When finished material is supplied to a purchase orderspecifying the product specification, the organization supply-ing that material shall provide the purchaser with a copy of theoriginal manufacturers test report.NOTE 2Notwithstanding th

45、rs test report wasprovided by EDI to the organization supplying the finishedmaterial to the purchaser, the organization supplying thefinished material shall provide to the purchaser a printed formof the original test report or shall retransmit the test report byEDI to the purchaser. In either case,
46、the test report shall becomplete with the full identification of the original manufac-turer and with all data provided on the test report of the originalmanufacturer.9. Permitted Variations in Dimensions and Weight9.1 Sheet, strip, and plate shall conform to the permittedvariations in thickness, wid
