(C) The requirements for chemical coniposition. grain size wherc applicable), hardness, final heat treatment and mechanical properties shall be identical to the requirements of the ASME material specitication.
(d) \Vhen a material does not meet a wrought material specification in ASME Section II. the Additive Manufacturer may request approval of a new material from ASME in accordance with the requirements of Appendix S of ASME BPVC Section II. Part D Ill.
(e) All material processing and testing shall meet the requirements of the Additive Manufacturing Specification and these criteria.
Commentary
The material for the AM component is the additively manufactured component in its final heat-treated condition. The Additive Manufacturer shall select a listed wrought ASME material specification from ASME HPVC Section Il for the AM component material. The selected ASME material specification shall be identified in the Additive Manufacturing Specification. The AM Committee reviewed data generated by several additive manufacturers and determined that AM component propenies are appropriate to meet wrought specifications 121 when the additive manufacturer has achieved control of the AM process through rigorous qualification testing (see Section 8). Specifying the use of wrought material for AM component material follows the same direction used for the recent additions to ASME Code for components manufactured using powder metallurgy/hot isostatic pressing technology. The AM material shall meet the ASME material specification requirements for chemical composition, grain sire. hardness, final heat treatment and mechanical properties. When a material for use in an AM build does not meet a wrought material specification in ASMF. Section II. the Additive Manufacturer may request approsal of a new material from ASME itt accordance with the requirements of ASME Section 11. Pan I.). Appendix 5 III. As additive manufacturing becomes more common, the need will eXist for new material with thermal treatments opunuzed br the powder bed fusion process, and thus, new materials will he needed for Code application.
