3、of Defense.1. Scope*1.1 This specification2 covers a group of general requirements that, unless otherwise specified in the purchase order or in anindividual specification, shall apply to rolled steel plate, sheet, and strip, under each of the following specifications issued byASTM: Specifications A2

4、40/A240M, A263, A264, A265, A666, A693, A793, and A895.1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the productspecification shall prevail. In the case of conflict between a requirement of the product specification or a require

5、ment of thisspecification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase orderrequirements shall not take precedence if they, in any way, violate the requirements of the product specification or thisspecification; for example, by waiving a test

6、 requirement or by making a test requirement less stringent.1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets, except that when A480M is specified, Annex A3 shall apply for the dimensional tolera

7、nces and not thebracketed SI values in Annex A2. The values stated in each system are not exact equivalents; therefore, each system must be usedindependently of the other. Combining values from the two systems may result in nonconformance with the specification.1.4 This specification and the applica

8、ble material specifications are expressed in both inch-pound and SI units. However, unlessthe order specifies the applicable “M” specification designation SI units, the material shall be furnished in inch-pound units.2.

Heat Analysis6.1 Methods and practices relating to chemical analysis shall be in accordance with Test Methods, Practices, and TerminologyA751.6.2 An analysis of each heat s

31、hall be made by the steel producer to determine the percentages of the elements specified in theapplicable material specification. This analysis shall be made from a test sample taken during the pouring of the melt, or from thein-process product later in the manufacturing flow.6.2.1 The heat analysi

32、s shall conform to the chemical requirements for each of the specified elements for the grade ordered, aslisted in the applicable product specification.6.2.2 All commercial metals contain small amounts of elements other than those which are specified. It is neither practical nornecessary to specify

33、limits for unspecified elements, whether intentionally added unspecified elements, residual elements, or traceelements, elements that can be present. The producer is permitted to analyze for unspecified elements and is permitted to reportsuch analyses. The presence of an unspecified element and the

34、reporting of an analysis for that element shall not be a basis forrejection, unless the presence of that element causes the loss of a property typically expected for that metal, for the type and qualityordered.6.2.3 The purchaser is permitted to require in the purchase order a maximum limit for an i

35、ndividual element not specified inthe product specification. Such a requirement for an element not listed in the product specification, when acknowledged in the orderacceptance, shall be treated as a specified element, with determination of chemical analysis and reporting of that analysis.6.2.4 The

36、purchaser is permitted to make the requirements for any element more stringent, that is, require higher minimums forelements having minimum requirements or ranges with minimum requirements, or requiring lower maximums for elements havingspecified maximums, or ranges with maximums. The purchaser is n

37、ot permitted to make chemical requirements less stringent.6.2.5 Analysis limits shall be established for specific elements rather than groups of elements, including but not limited to allothers,rare earths, and balance, unless all elements in such a group are similar in technical effect and are asso

38、ciated in typicalmethods of chemical analysis.6.3 Except as permitted in 6.3.1, the steel shall not contain an unspecified element for the ordered grade to the extent that thesteel conforms to the requirements of another grade for which that element is a specified element having a required minimumco

39、ntent. For this requirement, a grade is defined as an alloy described individually and identified by its own UNS designation ina table of chemical requirements within this specification or any specification listed within the scope as being covered by thespecification.6.3.1 Unless otherwise specified

40、 to lower maximum limits on the purchase order, maximum allowances for unspecified elementswill be established for Cu, Mo, Ti and Cb for the specified grade if the amount of that element present in the material conflictswith composition limits for that element in another grade. These allowances are:

41、 Cu, 0.75 %; Mo, 0.75 %; Ti, 0.10 %; and Cb,0.10 %.6.4 The producer is not permitted to certify that material is in compliance with an ASTM product specification when thepurchase order has required that the material contain as a minimum or range an element that is neither a specified element nor ani

42、ntentionally added unspecified element for the ordered grade in accordance with the definitions of Test Methods, Practices, andTerminology A751.7. Product Analysis7.1 The purchaser is permitted to perform a product analysis (formerly check analysis) to verify the identity of the finishedmaterial rep

43、resenting each heat or lot. Such analysis shall be made by any of the commonly accepted methods that will positivelyidentify the material.7.2 The chemical composition determined in accordance with 7.1 shall conform to the limits of the material specification withinthe tolerances of TableA1.1, unless

44、 otherwise specified in the applicable material specification or the purchase order.The allowablevariation of a particular element in a single sample for product analysis is permitted to be either above or below the specified range.However, percentages must exhibit the same tendencies in all samples

45、; that is, the several determinations of any individual elementin a heat shall not vary 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 product specification shall be supplied to the purchaser. This material t

46、estreport shall reference the product specification designation and year date indicating that the material was manufactured, sampled,tested, and inspected in accordance with requirements of the product specification and has been found to meet those requirements.The material test report shall report

47、the melting process when the purchase order requires either a specific type of melting orrequires that the melting process used is to be reported.8.1.1 The report shall indicate the type of steel. If certifying that the material conforms to the requirements for more than onetype of steel, the manufa

48、cturer may indicate each type of steel on the report, or may issue a separate report for each type of steel.8.2 A signature is not required on the report. However, the document shall clearly identify the organization submitting thereport. Not withstanding the absence of a signature, the organization

49、 submitting the document is responsible for its content.A480/A480M 16a38.3 A material test report, certificate of inspection, or similar document printed from or used in electronic form from anelectronic data interchange (EDI) transmission shall be regarded as having the same validity as a counterpart printed in thecertifiers facility. The content of the EDI transmitted document must meet the requirements of the invokedASTM standard(s) andconform to any existing EDI agreement between the purchaser and the supplier. Notwithstanding the absence of a
