Scope1.1 This specification2covers five grades of zirconium strip, sheet, and plate.1.2 Unless a single
3、 unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI unitsare to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system mustbe used independently of the other. SI values cannot be mixed w
4、ith inch-pound values.1.3 The following precautionary caveat pertains only to the test method portions of this specification: This standard does notpurport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard toestablish approp

Materials and Manufacture6.1 Material covered by this
19、specification shall be made from ingots that are produced by vacuum or plasma arc melting,vacuum electron-beam melting, a combination of these three methods or other melting processes conventionally used for reactivemetals. All processes to be done in furnaces usually used for reactive metals.6.2 Th
20、e various mill products covered by this specification shall be formed with the conventional extrusion, forging, or rollingequipment normally found in primary ferrous and nonferrous plants.6.3 The strip, sheet, and plate shall be supplied in the recrystallized annealed condition unless otherwise spec
21、ified in thepurchase order.7. 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. Mechanical Properties8.1 The material, as represented by the test specimens
33、, shall conform to the tensile properties prescribed in Table 3 for roomtemperature mechanical properties.8.2 For strip and sheet, the bend test specimen shall stand being bent at ambient temperature through an angle of 105 withoutfracture in the outside of the bent portion.
