This specification covers five grades of zirconium strip, sheet, and plate. These are low oxygen zirconium (Grade R60700), unalloyed zirconium (Grade R60702), zirconium-tin (Grade R60704), zirconium-niobium (Grade R60705), and zirconium-niobium (Grade R60706). The materials 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 reactive metals. All processes to be done in furnaces usually used for reactive metals. The various mill products covered by this specification are formed with the conventional extrusion, forging, or rolling equipment normally found in primary ferrous and nonferrous plants. The strip, sheet, and plate shall be supplied in the recrystallized annealed condition unless otherwise specified in the purchase order. The materials shall be subjected to chemical analysis and tensile strength, yield strength, elongation, bend, and flatness tests.
