This specification covers unalloyed and alloyed tantalum ingots prepared by vacuum-arc melting, electron-beam melting, or powder-metallurgy consolidation to produce consolidated metal for processing to various mill shapes. The materials covered by this specification are classified according to types: R05200; R05400; R05255; R05252; and R05240. The ingot metal for types R05200, R05255, R05252, and R05240 may be prepared by vacuum-arc melting, electron beam furnace melting, or a combination of these two methods. The metal for type R05400 is defined as powder-metallurgy consolidation unalloyed tantalum. The material shall conform to the chemical composition requirements for carbon, oxygen, nitrogen, hydrogen, niobium, iron, titanium, tungsten, molybdenum, silicon, nickel, and tantalum.
