Scope1.1 This specification covers four grades of wrought zirconium and zirconium alloy bars, rod, and wire as follows:1.1.1 R60001Unalloyed grade,1.1.2 R60802Zirconium-Tin alloy (Zircaloy 2),1.1.3 R60804Zirconium-Tin alloy (Zircaloy 4), and1.1.4 R60901Zirconium-Ni
4、obium alloy.1.2 Unless a single 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 oth
5、er. SI values cannot be mixed with 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 t

24、nregulated or unanalyzed scrap additions to the ingot melt. Therefore, product analysis for elements not listed inTable 1 shall not be required unless specified in the purchase order and shall be considered to be in excess of the intent of thisspecification.6.1.2 Elements intentionally added to the

27、ions relative to the ingot, as specified in SpecificationB350/B350M, to determine the composition, except for hydrogen, oxygen, and nitrogen, which shall be determined on the finishedproduct.6.3 Check Analysis:B351/B351M 1326.3.1 Check analysis is an analysis made by the purchaser or the manufacture
28、r 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 lot or to determine variations in thecomposition within a heat or lot.6.3.2 Check analysis limits shall be as specified in Table 2.6.3.3 Check analysis toleranc
29、es do not broaden the specified heat analysis requirements but cover variations betweenlaboratories in the measurement of chemical content.6.3.4 The manufacturer shall not ship material that is outside the limits specified in Table 1 for the applicable grade.7. Mechanical Properties7.1 The material,
30、 as represented by the test specimens, shall conform to the tensile properties prescribed in Table 3 when testedat ambient temperature.
