This specification covers UNS R60001, R60802, R60804, and R60901 wrought zirconium and zirconium alloy bars, rods, and wires. All material grades covered should conform to the required chemical composition requirements. Elements that are intentionally added to the melt should be identified, analyzed and reported in the chemical analysis. The zirconium and zirconium alloys should be made from ingots produced by vacuum or plasma arc melting, vacuum electron-beam melting, a combination of the three methods, or other melting processes conventionally used for reactive metals. All processes should be performed in furnaces specifically for reactive metals. Mill products included in this specification should be formed with conventional extrusion, forging, or rolling equipment that is used in primary ferrous and nonferrous plants. The cold worked and annealed materials should be in fully annealed condition unless otherwise specified. Hot worked shapes should be furnished in not descaled, mechanically descaled, or mechanically descaled and pickled finish, while cold-worked shapes should be furnished in cold-worked, ground, or pickled finish.1.1 This specification covers four grades of wrought zirconium and zirconium alloy bars, rod, and wire as follows:1.1.1 R60001—Unalloyed grade,1.1.2 R60802—Zirconium-Tin alloy (Zircaloy 2),1.1.3 R60804—Zirconium-Tin alloy (Zircaloy 4), and1.1.4 R60901—Zirconium-Niobium 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 units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. 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 not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Flat-rolled electrical steel master coils are usually slit into narrower coils. Usually these slit coils are punched or sheared into laminations of various shapes. The laminations are then uniformly stacked to become the cores of magnetic devices such as motors and transformers. Stacking of many laminations exhibiting excessive taper causes assembly problems and poor appearance. Nonuniform stack lengths in motors cause imbalance and noise. When the laminations are interleaved in transformers, taper causes air spaces within the core resulting in increased noise, increased exciting current, and higher core loss.1.1 This test method provides a procedure for measuring edge taper and crown of flat-rolled electrical steel coils as produced at the steel mill.1.2 The values and equations stated in customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within this standard, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard.1.3 The following material specifications include requirements for edge taper or crown: A677, A683, A726, A876, and A1086. Specification A840 also includes requirements for edge taper or crown, but it has been withdrawn and reference to it is included for historical purposes.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the standard for cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The sheet shall be produced from aluminum killed steel and shall undergo continuous annealing to austenitic temperatures and then be water quenched. Cast or heat analysis shall conform to the prescribed chemical composition requirements in carbon, manganese, phosphorus, sulfur, and aluminum. Tension test shall be done on the point immediately adjacent to the material to be tested and properties shall conform to the specified tensile strength. The sheet shall have a matte surface finish texture and shall have cut edges. Unless otherwise specified, the sheet shall undergo oiling.1.1 This specification covers a cold rolled ultra high strength carbon steel sheet in coils or cut lengths. The product is available in five strength levels. The steel's strength is obtained by water quenching from an austenitic temperature resulting in a martensitic microstructure. This product is intended for miscellaneous applications where ultra high strength, weight saving, and good weldability are important.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
