1、Designation: A480/A480M 14Standard Specification forGeneral Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip1This standard is issued under the fixed designation A480/A480M; the number immediately following the designation indicates the yearof original adoption
2、or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. 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 A167, A176, A240/
4、A240M,A263, A264, A265, A666, A693, A793, and A895.1.2 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 arequirement of
5、 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 atest requir
6、ement 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 A480M isspecified, Annex A3 shall apply for the dimensional tolerancesand n
7、ot the bracketed SI values in AnnexA2. 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 applicable material
8、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.

Process5.1 The steel shall be manufactured/produced by the follow-ing or as specified in the applicable material specification.5.1.1 The steel shall be
28、made by one of the followingprocesses: electric-arc, electric-induction, or other suitableprocesses.5.1.2 If a specific type of melting is required by thepurchaser, it shall be so specified on the purchase order.6. Heat Analysis6.1 Methods and practices relating to chemical analysisshall be in accor
29、dance with Test Methods, Practices, andTerminology A751.6.2 An analysis of each heat shall be made by the steelproducer to determine the percentages of the elements specifiedin the applicable material specification. This analysis shall bemade from a test sample taken during the pouring of the melt,o
30、r from the in-process product later in the manufacturing flow.6.2.1 The heat analysis shall conform to the chemicalrequirements for each of the specified elements for the gradeordered, as listed in the applicable product specification.6.2.2 All commercial metals contain small amounts ofelements othe
31、r than those which are specified. It is neitherpractical nor necessary to specify limits for unspecifiedelements, whether intentionally added unspecified elements,residual elements, or trace elements, that can be present. Theproducer is permitted to analyze for unspecified elements andis permitted t
32、o report such analyses. The presence of anunspecified element and the reporting of an analysis for thatelement shall not be a basis for rejection, unless the presence ofthat element causes the loss of a property typically expected forthat metal, for the type and quality ordered.5Available from Autom

Such a requirement for an elementnot listed in the
35、 product specification, when acknowledged inthe order acceptance, shall be treated as a specified element,with determination of chemical analysis and reporting of thatanalysis.6.2.4 The purchaser is permitted to make the requirementsfor any element more stringent, that is, require higher mini-mums f
36、or elements having minimum requirements or rangeswith minimum requirements, or requiring lower maximums forelements having specified maximums, or ranges with maxi-mums. The purchaser is not permitted to make chemicalrequirements less stringent.6.2.5 Analysis limits shall be established for specifice
37、lements rather than groups of elements, including but notlimited to all others, rare earths, and balance, unless allelements in such a group are similar in technical effect and areassociated in typical methods of chemical analysis.6.3 Except as permitted in 6.3.1, the steel shall not containan unspe
38、cified element for the ordered grade to the extent thatthe steel conforms to the requirements of another grade forwhich that element is a specified element having a requiredminimum content. For this requirement, a grade is defined asan alloy described individually and identified by its own UNSdesign
39、ation in a table of chemical requirements within thisspecification or any specification listed within the scope asbeing covered by the specification.6.3.1 Unless otherwise specified to lower maximum limitson the purchase order, maximum allowances for unspecifiedelements will be established for Cu, M
40、o, Ti and Cb for thespecified grade if the amount of that element present in thematerial conflicts with composition limits for that element inanother grade. These allowances are: Cu, 0.75 %; Mo, 0.75 %;Ti, 0.10 %; and Cb, 0.10 %.6.4 The producer is not permitted to certify that material isin complia
41、nce with an ASTM product specification when thepurchase order has required that the material contain as aminimum or range an element that is neither a specifiedelement nor an intentionally added unspecified element for theordered grade in accordance with the definitions of TestMethods, Practices, an
42、d Terminology A751.7. Product Analysis7.1 The purchaser is permitted to perform a product analysis(formerly check analysis) to verify the identity of the finishedmaterial representing each heat or lot. Such analysis shall bemade by any of the commonly accepted methods that willpositively identify th
43、e material.7.2 The chemical composition determined in accordancewith 7.1 shall conform to the limits of the material specificationwithin the tolerances of Table A1.1, unless otherwise specifiedin the applicable material specification or the purchase order.The allowable variation of a particular elem
44、ent in a singlesample for product analysis is permitted to be either above orbelow the specified range. However, percentages must exhibitthe same 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
45、. Material Test Report and Certification8.1 Areport of the results of all tests required by the productspecification shall be supplied to the purchaser. This materialtest report shall reference the product specification designationand year date indicating that the material was manufactured,sampled,
46、tested, and inspected in accordance with requirementsof the product specification and has been found to meet thoserequirements. The material test report shall report the meltingprocess when the purchase order requires either a specific typeof melting or requires that the melting process used is to b
47、ereported.8.1.1 The report shall indicate the type of steel. If certifyingthat the material conforms to the requirements for more thanone type of 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
48、 on the report. However, thedocument shall clearly identify the organization submitting thereport. Not withstanding the absence of a signature, theorganization submitting the document is responsible for itscontent.8.3 Amaterial test report, certificate of inspection, or similardocument printed from
49、or used in electronic form from anelectronic data interchange (EDI) transmission shall be re-garded as having the same validity as a counterpart printed inthe certifiers facility. 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 EDItransmission is responsible for the content of the report.8.4 When finished material is supplied to a purchase orders
