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.
Abstract
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
1.2 The materials covered by this specification are:
1.2.3 R05255, tantalum alloy, 90 % tantalum, 10 % tungsten, 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 and health practices and determine the applicability of regulatory limitations prior to use.
