Chemical Composition7.1 The material covered by this specification shall conform to the chemical composition requirements prescribed in Table 1.7.1.1 The elements listed in Table 1 are intentional alloy additions or elements which are inherent to the manufacture of spon

22、ge,ingot or mill product.7.1.2 Elements intentionally added to the melt must be identified, analyzed, and reported in the chemical analysis.7.1.3 Elements other than those listed in Table 1 are deemed to be capable of occurring in the grades listed in Table 1 by andonly by way of unregulated or unan

23、alyzed scrap additions to the ingot melt. Therefore, product analysis for elements not listed inTable 1 shall not be required unless specified and shall be considered to be in excess of the intent of this specification.7.1.4 When agreed upon by producer and purchaser and requested by the purchaser i

24、n his written purchase order, chemicalanalysis shall be completed for specific residual elements not listed in this specification.7.2 The manufacturers ingot analysis shall be considered the chemical analysis for strip, sheet, and plate, except for hydrogenand nitrogen, which shall be determined on

25、the finished product.7.2.1 The ingot shall be sampled in sufficient places along the side wall so that the top sample is within 5 in. 125 mm of thetop face. A minimum of three samples per ingot is required.TABLE 1 Chemical RequirementsAElementComposition, %GradesR60700 R60702 R60704 R60705 R60706Zir

28、zed for the alloying and impurity elements given in Table 1.7.2.3 Alternatively, the manufacturer may sample an intermediate or final size during processing with the same frequency andin the same positions relative to the ingot as specified in 7.2.1 to determine the composition, except for hydrogen

29、and nitrogen,which shall be determined on the finished product.7.3 Check Analysis:7.3.1 Check analysis is an analysis made by the purchaser or the manufacturer of the metal after it has been processed intofinished mill forms, and is either for the purpose of verifying the composition of a heat or lo

30、t or to determine variations in thecomposition within a heat or lot. Acceptance or rejection of a lot of material may be made by the purchaser on the basis of thischeck analysis. When requested by the purchaser and stated in the purchase order, a product check analysis for any elements listedin Tabl

31、e 1 shall be made on the finished product.7.3.2 Check analysis limits shall be as specified in Table 2. These limits are the amounts an individual result for a given elementmay vary under or over the specified limits shown in Table 1.7.3.3 Check analysis tolerances do not broaden the specified heat

32、analysis requirements but cover variations betweenlaboratories in the measurement of chemical content.7.3.4 The manufacturer shall not ship material that is outside the limits specified in Table 1 for the applicable grade.8.
