Ingot analysis may be used for reporting allchemical requirements, except hydrogen. Samples for hydrogen shall be t
30、aken from the finished mill product, and the supplier shallnot ship material with chemistry outside the requirements specified in Table 1.7.1.1 Requirements for the major and minor elemental constituents are listed in Table 1. Also listed are important residualelements. Analysis for elements not lis
31、ted in Table 1 is not required to verify compliance with this specification.7.2 Product Analysis:7.2.1 Product analysis tolerances do not broaden the specified heat analysis requirements but cover variations betweenlaboratories in the measurement of chemical content. The manufacturer shall not ship
32、material that is outside the limits specifiedin Table 1. The product analysis tolerances shall conform to the product tolerances in Table 2.7.2.2 The product analysis is either for the purpose of verifying the composition of a heat or manufacturing lot or to determinevariations in the composition wi
33、thin the heat.7.2.3 Acceptance or rejection of a heat or manufacturing lot of material may be made by the purchaser on the basis of thisproduct analysis. Product analyses outside the tolerance limits allowed in Table 2 are cause for rejection of the product. A refereeanalysis may be used if agreed u
34、pon by the supplier and purchaser.7.2.4 For referee purposes, use Test Methods, E539, E1409, E1447, E1941, and E2371 or other analytical methods agreed uponbetween the purchaser and the supplier.7.3 Samples for chemical analysis are representative of the material being tested. The utmost care must b

In cutting samples foranalysis, therefore, the operation should be carried out insofar as possible in a dust-free atmosphere. Cutting tools should be cleanand sharp. Samples
36、for analysis should be stored in suitable containers.8. Mechanical Requirements8.1 The material supplied under this specification shall conform to the mechanical property requirements in Table 3 or Table4.8.2 Specimens for tension tests shall be machined and tested in accordance with Test Methods E8
37、E8/E8M. Tensile propertiesshall be determined using a strain rate of 0.003 to 0.007 in./in./min (mm/mm/min)mm/mm/min through the specified yield andthen the crosshead speed shall be increased so as to produce fracture in approximately one additional minute.8.3 For sheet and strip, the bend test spec

The bend shall be made over a mandrel with a diameter equal to that shown in Table 4. Testconditions shall conform to Test Method E290.8.4 Number of Tests:8.4.1 Bar, Forging Bar,

Dimensions, Mass, and Permissible Variations9.1 Units of Measure:9.1.1 SelectionThis specification requires that the purchaser select the units (SI or inch-pound) to be used for productcertification. In the absence of a stated selection of units on the purchase order, this
47、selection may be expressed by the purchaserin several alternate forms listed in order of precedence.9.1.1.1 If the purchaser and supplier have a history of using specific units, these units shall continue to be certified untilexpressly changed by the purchaser.9.1.1.2 In the absence of historic prec
48、edence, if the units used to define the product on the purchasers PO, specification, andengineering drawing are consistent, these units shall be used by the supplier for product certification.9.1.1.3 If the purchasers selection of units is unclear, the units of measure shall be agreed upon between t
49、he purchaser andsupplier.9.1.2 Conversion of UnitsIf the suppliers test equipment does not report in the selected units, the test equipment units maybe converted to the selected units for certification purposes. Accurate arithmetic conversion and proper use of significant digitsshould be observed when performing this conversion. IEEE/ASTM SI 10 provides guidelines for the use of SI units. Annex A ofthat standard provides conversion tables and Annex B provides rules for conversion and significance.10. Special Requ
