4、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 arequirem

5、ent 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 atest

6、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 toleranc

7、esand not the bracketed SI values inAnnexA2. 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 mat

8、erial 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.

Ordering Information4.1 It is the

21、 responsibility of the purchaser to specify allrequirements that are necessary for material ordered under thisspecification. Such requirements may include, but are notlimited to, the following:4.1.1 Quantity (weight and number of pieces),4.1.2 Name of material (stainless steel),4.1.3 Condition (hot-

22、rolled, cold-rolled, annealed, heat-treated),4.1.4 Finish (see Section 11 for Sheet, Section 12 for Strip,and Section 13 for Plates). In the case of polished finishes,specify whether one or both sides are to be polished,4.1.5 Temper (if the applicable material specification re-quires this detail),4.

23、1.6 Form (plate, sheet, or strip),4.1.7 Dimensions (thickness, width, length),4.1.7.1 Thickness shall be ordered to decimal or fractionalthickness. The use of the gage number is discouraged as beingan archaic term of limited usefulness not having generalagreement on meaning. The gage number shall no

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 made by one of the followingprocesses: electric-arc, electric-induction, or other suitableprocesses.5.1.2 If a spec

28、ific 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 accordance with Test Methods, Practices, andTerminology A 751.6.2 An analysis of each heat shall be made by the steelpro

29、ducer 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,or from the in-process product later in the manufacturing flow.6.2.1 The heat analysis shall conform to the chemica

30、lrequirements 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 other than those which are specified. It is neitherpractical nor necessary to specify limits for unspecified ele-ments

31、, whether intentionally added unspecified elements, re-sidual elements, or trace elements, that can be present. Theproducer is permitted to analyze for unspecified elements andis permitted to report such analyses. The presence of anunspecified element and the reporting of an analysis for thatelement

32、 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.6.2.3 The purchaser is permitted to require in the purchaseorder a maximum limit for an individual element not specified4Available

Such a requirement for an elementnot listed in the product specification, when acknowledged inthe order acceptance, shall be treated as a specified element,w

36、elements 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 specificelements rather than groups of elements, including but notlimited to all others, rare earths, and balance, u

37、nless allelements in such a group are similar in technical effect and areassociated in typical methods of chemical analysis.6.3 The steel shall not contain an unspecified element forthe ordered grade to the extent that the steel conforms to therequirements of another grade for which that element is

38、aspecified element having a required minimum content. For thisrequirement, a grade is defined as an alloy described individu-ally and identified by its own UNS designation in a table ofchemical requirements within this specification or any specifi-cation listed within the scope as being covered by t

39、he specifi-cation.6.4 The producer is not permitted to certify that material isin compliance 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 elem

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 ana

41、lysis 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 tolerances of Table A1.1, unless otherwise specifiedin the applicable

42、 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 tendencies in all samples; that is, the severaldeterminations of

43、 any individual element in a heat shall notvary both above and below the specified range.8. 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 spec

44、ification 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 test report shall report the meltingprocess when the purchase order r

45、equires 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 of steel, the manufacturer may indicate each type ofsteel on the re

46、port, 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, theorganization submitting the document is responsible for itscont

The content of the EDI transmi

48、tteddocument 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 f
