ASTM-B365 › Standard Specification for Tantalum and Tantalum Alloy Rod and Wire
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers unalloyed and alloyed tantalum rod and wire. The materials covered are: R05200, R05400, R05255, R05252, and R05240. These materials shall be made from vacuum-arc melted or electron-beam melted ingots or powder-metallurgy consolidated unalloyed tantalum. The chemical composition shall conform to the required contents of carbon, oxygen, nitrogen, hydrogen, niobium, iron, titanium, tungsten, molybdenum, silicon, nickel, and tantalum. Chemical analysis shall be made. Mechanical properties shall conform to the required tensile strength, yield strength, and elongation.
Scope
1.1 This specification covers unalloyed and alloyed tantalum rod and wire.
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 % niobium, electron-beam furnace or vacuum-arc melt, or both.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The following precautionary caveat pertains only to the test methods portion, Section 13, of this specification: This standard does not purport to address all of the safety problems, 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.
Significance and Use
12.1 For the purpose of determining compliance with the specified limits for requirements on the properties listed in this specification, observed and calculated values shall be rounded as indicated by the rounding method of Practice E29.
