    ASTM B988

    Abstract

    This specification covers powder metallurgy (PM) structural components fabricated from commercially pure (CP) (that is, unalloyed) titanium powder, pre-alloyed powders, and mixtures of elemental powders or mixtures of elemental powders and pre-alloyed powders. It addresses ordering information, materials and manufacture, chemical composition requirements, tensile requirements, physical properties, mechanical properties, dimensions, mass, permissible variations, sampling, inspection, and certification.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. 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 and health practices and determine the applicability of regulatory limitations prior to use.
