    Withdrawn Rationale:

    This specification covers unalloyed and alloyed tantalum ingots prepared by vacuum-arc melting, electron-bean melting, or powder-metallurgy consolidation to produce consolidated metal for processing to various mill shapes.

    Formerly under the jurisdiction of Committee B10 on Reactive and Refractory Metals and Alloys, this specification was withdrawn in January 2018 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    1.1 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.

    1.2 The materials covered by this specification are:

    1.2.1 R05200, unalloyed tantalum, electron-beam furnace or vacuum-arc melt, or both,

    1.2.2 R05400, unalloyed tantalum, powder-metallurgy consolidation,

    1.2.3 R05255, tantalum alloy, 90 % tantalum 10 % tungsten, electron-beam furnace or vacuum-arc melt, or both,

    1.2.4 R05252, tantalum alloy, 97.5 % tantalum 2.5 % tungsten, electron-beam furnace or vacuum-arc melt, or both, and,

    1.2.5 R05240 tantalum alloy, 60 % tantalum 40 % columbium, electron-beam furnace or vacuum-arc melt, or both.
