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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 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.

Overview

ASTM F3184-16(2023): Standard Specification for Additive Manufacturing Stainless Steel Alloy (UNS S31603) with Powder Bed Fusion provides comprehensive requirements for producing stainless steel components using additive manufacturing (AM) techniques such as laser-based and electron beam-based full melt powder bed fusion processes. This standard is designed to ensure that manufactured parts achieve mechanical properties comparable to those produced by conventional machining, forging, or wrought processes. Importantly, it facilitates traceability, process control, and quality assurance for manufacturers, suppliers, and end-users in sectors demanding high-performance stainless steel parts.

Key Topics

• Material Specification
  • Defines chemical composition requirements for UNS S31603 stainless steel powder and finished components.
  • Specifies requirements for powder quality, including type, size distribution, and allowable blends of virgin and used powder, supporting both laser and electron beam powder bed fusion processes.
• Manufacturing Processes
  • Covers process parameters, machine qualification, and mandatory documentation for every production stage.
  • Outlines optional and required post-processing methods, including machining, grinding, EDM, polishing, stress relief, solution annealing, and hot isostatic pressing (HIP).
• Quality and Certification
  • Establishes procedures for mechanical testing (tensile, fatigue, hardness, fracture toughness) to verify properties.
  • Details steps for inspection, retesting, rejection, as well as component marking, packaging, and certification.
• Customization
  • Allows for supplementary requirements in purchase orders to meet more stringent application-specific needs, such as enhanced mechanical performance or tightened tolerances.

Applications

This ASTM specification is vital for industries that demand stainless steel components with high strength, corrosion resistance, and consistent quality, manufactured using additive methods. Key application areas include:

• Aerospace and Defense: Production of complex, lightweight structural components that meet strict mechanical performance criteria.
• Industrial Engineering: Fabrication of parts requiring reliable mechanical properties, similar to forgings and wrought items, but benefiting from the design flexibility of additive manufacturing.
• Process Equipment and Pressure Vessels: Creation of critical parts for chemical processing, oil and gas, and power generation needing durable and corrosion-resistant materials.
• Tooling and Custom Manufacturing: Rapid prototyping and customized component production with specific surface finishes and dimensional accuracy.
• Non-Medical Applications: Note: This standard does not cover surgical implant-grade material (UNS S31673).
