Historical Standard: Standard Specification for Powder Metallurgy (PM) Titanium and Titanium Alloy Structural Components
ASTM B988
Scope
1.1 This specification covers powder metallurgy (PM) structural components fabricated from:
1.1.1 Commercially pure (CP) (that is, unalloyed) titanium powder,
1.1.2 Pre-alloyed powders.
1.1.3 Mixtures of elemental powders or mixtures of elemental powders and pre-alloyed powders.
1.2 This specification covers:
1.2.1 Grade 1 PM—Unalloyed titanium,
1.2.2 Grade 2 PM—Unalloyed titanium,
1.2.3 Grade 3 PM—Unalloyed titanium,
1.2.4 Grade 4 PM—Unalloyed titanium,
1.2.5 Grade 5 PM—Titanium alloy (6 % aluminum, 4 % vanadium),
1.2.6 Grade 9 PM—Titanium alloy (3 % aluminum, 2.5 % vanadium),
1.2.7 Ti-6Al-4V PM Low Interstitial (LI),
1.2.8 Ti-6Al-6V-2Sn PM.
1.3 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, 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.
