Description

ASTM F3635-23

Active Standard: Standard Specification for Additive Manufacturing – Finished Part Properties – Standard Specification for Niobium-Hafnium Alloy UNS R04295 via Laser Beam Powder Bed Fusion for Spaceflight Applications

ASTM F3635

Scope

1.1 This specification covers additive manufacturing of parts manufactured via laser beam powder bed fusion (PBF-LB) processing of niobium-hafnium alloy used in spaceflight applications. Parts made using this processing method are typically used in applications that require mechanical properties like wrought products. Products built to this specification may require additional post-processing in the form of machining, polishing etc. to meet necessary surface finish and dimensional tolerances.

1.2 This specification is intended for the use of purchasers or producers, or both, of PBF-LB R04295 parts for defining the requirements based on classification methodology. These requirements shall be agreed upon by the part supplier and purchaser.

1.3 Users are advised to use this specification as a basis for obtaining parts that will meet the minimum acceptance requirements established and revised by consensus of committee members.

1.4 User requirements considered more stringent may be met by the addition to the purchase order.

1.5 Units—The values stated in SI units are to be regarded as the standard. Other units are included only for informational purposes.

1.6 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.

1.7 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.
