Standard Specification for Additive Manufacturing Stainless Steel Alloy (UNS S31603) with Powder Bed Fusion

ABSTRACT
This specification establishes the requirements for additive manufacturing of stainless steel alloy (UNS S31603) components by means of laser and electron beam-based full melt powder bed fusion processes. The components produced by these processes are typically used 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 specification covers Condition A and Condition B components, manufacturing plan, feedstock, processing, chemical composition, mechanical properties, microstructural requirements, thermal post-processing, hot isostatic pressing, retests, inspection and certification, product marking and packaging, and quality program requirements.
SCOPE
1.1 This specification covers additive manufacturing of UNS S31603 components by means of laser and electron beam-based full melt powder bed fusion processes. 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.  
1.2 This specification is intended for the use of purchasers or producers, or both, of additively manufactured UNS S31603 components for defining the requirements and ensuring component properties.  
1.3 Users are advised to use this specification as a basis for obtaining components that will meet the minimum acceptance requirements established and revised by consensus of the members of the committee.  
1.4 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 Supplementary Requirements S1–S16.  
1.5 The compositional requirements specified in this specification do not meet the compositional requirements for surgical implant grade UNS S31673.  
1.6 The values stated in SI units are to be regarded as the standard. Other units are included only for informational purposes.  
1.7 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.
