3、ense.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 A167, A1
4、76, A240/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 r
5、equirement 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
6、a test 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
7、tolerances 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 a
8、pplicable 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.

Process5.1 The steel shall be manufactured/produced by the following or as specified in the applicable material specification.5.1.1 The steel shall be made by one of the following proc
31、esses: electric-arc, electric-induction, or other suitable processes.5.1.2 If a specific type of melting is required by the purchaser, it shall be so specified on the purchase order.6. Heat Analysis6.1 Methods and practices relating to chemical analysis shall be in accordance with Test Methods, Prac
32、tices, and TerminologyA751.6.2 An analysis of each heat shall 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 produ
33、ct later in the manufacturing flow.6.2.1 The heat analysis 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 sp
34、ecified. It is neither practical nornecessary to specify limits for unspecified elements, whether intentionally added unspecified elements, residual elements, or traceelements, that can be present. The producer is permitted to analyze for unspecified elements and is permitted to report suchanalyses.
35、 The presence of an unspecified element and the reporting of an analysis for that element shall not be a basis for rejection,unless the presence of that element causes the loss of a property typically expected for that metal, for the type and quality ordered.6.2.3 The purchaser is permitted to requi
36、re in the purchase order a maximum limit for an individual 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 a
37、nalysis and reporting of that analysis.6.2.4 The 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 maxi
38、mums, or ranges with maximums. The purchaser is not 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 g
39、roup are similar in technical effect and are associated 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 i
40、s a specified element having a required minimumcontent. 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
41、thespecification.6.3.1 Unless otherwise specified 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 tha
42、t element in another 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 is in compliance with an ASTM product specification when thepurchase order has required that the material contain as a minimum or range an el
43、ement that is neither a specified element nor anintentionally 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) t
44、o verify the identity of the finishedmaterial representing 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 specif
45、ication withinthe tolerances of TableA1.1, unless 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, percentage
46、s must exhibit the same tendencies in all samples; 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 sh
47、all be supplied to the purchaser. This material testreport 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 re
48、quirements.The material test report shall report the melting process when the purchase order requires either a specific type of melting orrequires that the melting process used is to be reported.A480/A480M 1338.1.1 The report shall indicate the type of steel. If certifying that the material conforms
49、 to the requirements for more than onetype of steel, the manufacturer 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 submitting the document is responsible for its content.8.3 A material test report, certificate of inspection, or similar document printed from or used in electronic form from anelectronic da
