Abstract:

This specification defines the requirements for additive manufacturing of nickel alloy (UNS N07718) using full-melt powder bed fusion such as electron beam melting and laser melting. The standard may be used by purchasers and producers of additively manufactured UNS N07718 components to specify the requirements and ensure component properties, and by users to obtain components that will satisfy the minimum acceptance requirements. The standard covers terminology and classification as well as the requirements with respect to ordering information, manufacturing plan, feedstock, thermal processing, chemical composition, microstructure, mechanical properties, hot isostatic pressing, dimensions and permissible variations, retests, inspection, rejection, certification, product marking and packaging, maintenance of a quality program, and the significance of numerical limits.

Scope:

1.1 This specification covers additively manufactured UNS N07718 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.

1.2 This specification is intended for the use of purchasers or producers, or both, of additively manufactured UNS N07718 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 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

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