Annotation of standard text ASTM B776-12(2024) :
This specification covers the standard requirements for two grades of wrought hafnium and hafnium alloy strip, sheet, and plate: Grade R1 for nuclear applications and Grade R3 for commercial applications. The materials shall be made from ingots that are produced in a furnace by vacuum or plasma arc melting, vacuum electron-beam melting, a combination of these three methods, or other melting process conventionally used for reactive metals. The various mill products shall be formed with the conventional extrusion, forging, or rolling equipment normally found in primary ferrous and nonferrous plants. The sheet, strip, and plate shall either be hot-rolled or cold-rolled and shall be supplied in the recrystallized annealed condition. Grades R1 and R3 metal shall conform to the chemical composition requirements for aluminum, carbon, chromium, copper, hydrogen, iron, molybdenum, nickel, niobium, nitrogen, oxygen, silicon, tantalum, tin, titanium, tungsten, uranium, vanadium, zirconium, and hafnium as shall be determined by chemical analysis. Mechanical properties, which shall be determined by tension tests both in longitudinal and transverse direction, shall meet the prescribed tensile strength, yield strength, and elongation requirements. Corrosion testing in water shall also be performed to determine the corrosion resistance of the materials.
