New Specification for Additive Manufacturing -- Finished part properties -- Stainless Steel Alloys made by powder bed fusion
1. Scope
This document covers additively manufactured stainless steel components using full-melt powder bed fusion such as electron beam melting and laser melting. The components produced by these processes are used typically in applications that require mechanical properties similar to machined forgings and wrought products. Components manufactured to this specification are often, but not necessarily, post processed via machining, grinding, electrical discharge machining (EDM), polishing, and so forth to achieve desired surface finish and critical dimensions.
This document is intended for the use of mechanical engineers to size equipment, purchasers or producers, of additively manufactured components for defining the requirements and ensuring component properties.
Users are advised to use this document as a basis for obtaining components that will meet the minimum acceptance requirements established and revised by consensus of the members of the committee.
User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which may include, but are not limited to, those listed in Clause
5.
The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this document.
This document 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 document to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Rationale
No such standard presently exists - this document is being developed jointly with ISO TC261, via a PSDO agreement between ASTM and ISO. WRT this specific standard, the ultimate designation will be ISO/ASTM52946.
